Bambu Lab is abusing the open source social contract (jeffgeerling.com)

Full disclosure: I've never owned a Bambu because I've never loved the idea of a "closed" ecosystem 3D printer, however I have used them, and am very familiar with the 3d printing space beyond Bambu.

For anyone considering alternatives: You should know that almost all other 3D printers expect you to know a little more about how they actually work than Bambus. Bambus are as close as you can get to a "just works" type experience, but modern alternatives from others are nowhere near as hard as they used to be.

The closest "easy" alternative is probably Prusa, but you'll pay significantly more for a Prusa machine than you would a Bambu. They're an excellent company, and the complete opposite of Bambu when it comes to Openness. If money is no object, Prusa is highly recommended.

Beyond Prusa, there's a lot of other options. https://auroratechchannel.com/#section2 This list is a good one.

I personally run an old Elegoo Neptune 4 pro - but my needs are quite low. If I were buying today, a Snapmaker U1 or the Creality K2 Plus is probably where I'd end up going.

Prusa are pretty much plug and play these days, especially the Core One line-up.

You're right that they're expensive but you get free human support 24x7, you get an open platform, lots of contributions to open source (even Bambu Studio is a fork of Prusa Slicer), and they pretty much go on forever.

My Core One+ started its life as an original MK3 and went through each iteration of upgrades, and it works like new. I'm now waiting for an INDX upgrade for it.

IMO the main drawback of consumer Prusa offerings is the lack of good chamber heating for more advanced materials. I can print PC on my Core One+ in the summer with the chamber at 45℃ (good enough for most uses, but 60 would be better), but in the winter it becomes a lot harder.

The Core One L is supposedly better in that regard but I've seen reports that it's still not ideal.

Other than that, I feel the extra cash pays itself back in the long run.

DoctorOetker 19 hours ago

Is there any guidance on improving the Core One chamber? I would like to add some thermal insulation around the chamber, but I'm not sure if the firmware will properly detect unexpected thermal insulation in problematic scenario's, if it blindly assumes its a stock Core One... the more you modify a printer, the more it operates in terra incognita.

Could too much thermal insulation cause the bed temperature to lower (to avoid overheating chamber temp) to the point the print no longer adheres? etc.

If you could recommend some articles on the subject I would highly appreciate it.

How do you upgrade a Mk3 to a Core One?

Wow, that’s a lot of money on upgrades. I also got the MK3 and upgraded it once.

Full upgrade to the core one will be AUD$2k

I can keep my current printer alive for a long time. But it’s hard to justify the cost.

Prusa is still the most 'open source-ish' choice, but they're no longer a polar opposite to Bambu, in 2023 they started making efforts to stop commercialization of their designs, stopped sharing source/design material for their PCBs, etc.

Then in 2025 they changed their 'open community license' to say users may not:

“Sell complete machines or remixes based on these files, unless you have a separate agreement…” and “The Restriction: You cannot commercially exploit the design files…”

https://blog.prusa3d.com/core-one-cad-files-release-under-th...

Maybe this is more a comment on how open source has had to change in the face of commercial exploitation of the vulnerabilities traditional open source licenses create for the businesses doing the R&D.

Aurornis 18 hours ago

I've been a Prusa defender for a long time, including when they added the break-off tab to enable custom firmware which caused a lot of upset.

They're doing what it takes to be a business. I was glad when they moved to more injection molded parts instead of trying to 3D print their own parts. It was a cool idea at the start but the time for that was long past.

My only slight objection is that you can tell they're trying to have it both ways: They want all of the good will and reputation of being open source, but they're also trying hard to put as many limits on this as they can. Like all projects trying to walk the line between open and closed source, I think they're at their best when they're honest about what they're doing. The moves they made with their open license are completely reasonable and I support them, but that blog post was a bit of a letdown when they tried to make it about fighting patent trolls for the community or something. When you reach Prusa scale you have to be honest that you're no longer one and the same with the community. You are the medium-ish size business that people rely on. Taking away the right for others to sell the products is a reasonable business move, but please be honest about it rather than trying to tell us it's for our own good.

scottbez1 19 hours ago

It’s rough but I understand it.

You can be entirely in favor of the open source ethos, even as a commercial entity, but then certain actors can take advantage of that ethos and just directly commercialize your R&D investment and take all the proceeds of your investment, whether or not they comply with attribution or share-alike requirements.

It’s tough seeing an open source project you’ve poured tons of care and effort into (and WANT people to share and remix and build cool things) get more or less “extracted” for profit without contributing back (code or money).

At the end of the day, none of it really matters unless you’ve got money and time to actually try to enforce your licenses, or have enough customer mindshare to effectively change the behavior of bad actors without needing legal action.

I’ll probably use licenses like Prusas in the future for similar reasons, even though I generally prefer to use less restrictive ones. Bad actors, or even just non-benevolent actors, can really sour the open source ethos, and it sucks but there’s no way to legally enforce “don’t be a jerk” without restricting a legal document in slightly unpalatable ways.

Basically every "AWS ate open core company lunch thread" is filled with people arguing that releasing your products under an open source license is immoral because the company didn't foresee that a hosting provider is going to swallow them in 8 years to the point where the project would have to be abandoned. However, the immorality doesn't lie in the death of the project, no. The immorality lies in the continued existence of the project under a slightly more restrictive license.

It's always a headscratcher when you try to eeke out a living and are told that you have to work for a company writing proprietary software to have the right to work on an open source project. Wouldn't it be better if you made your living off the open source project? Apparently not. If the project was proprietary from the start, there would be no complaints.

This hardliner stance basically means there is no continuum between proprietary software and open source software. That lack of continuum will mean that the vast majority of software will always be 100% proprietary.

It’s not problematic to restrict people from selling the thing you designed, made and sell without permission.

If I make an open source car, I don’t want someone else taking my design work, and then selling a cheaper version of my product, I want my consumers to build their own parts.

If you decide to get a Bambu anyway, let me heartily recommend against an H2D.

It did "just work" for a while, but then the print cooling fan went bad. On my home Voron, this would be a 5 minute fix. On the H2D, it is this [0]. You basically have to take the entire toolhead apart, removing the mainboard inside it with no less than 11 very tiny and fragile custom ribbon cables that connect to it, plus 5 more connections on a second board that goes on top of it. Most minor fixes are like this. Another time, I had to remove a stuck piece of filament, which involved taking apart the whole front of the toolhead and dealing with even smaller and more fragile flex PCBs.

You're not the target market for Bambu customers.

This is like complaining that on your dirt track racer it's a trivial process to swap the rear end spur and change final drive ratios. Someone who has their dealership do the oil changes on their leased BMW does not care.

Maybe they should care a little, because the long-term repairability of their BMW or Bambu is going to put a real dent in their resale value. But they're not the ones dealing with tweezers and ZIF connectors and flex PCBs, so it's mostly just not their problem.

3D printers used to be exclusively the domain of people who enjoyed doing all this work themselves, who loved a well-designed machine that was a joy to work with like a Voron. That's no longer the case, Bambu is offering unrepairable black boxes that "just work" for enough time that some people can afford not to think care how it's made.

Sounds like RC quadcopters society -- everyone knows DJI, but they make fan guards a part of the frame. Guards and props are the most fragile parts, a consumable really. Something an enthusiast often carry spares for, to quickly swap on the field for any other RC quad, but with DJI you need what, send the whole frame to factory?

I like my H2D, but it definitely hit a brick wall. I replaced it, and had the same issue with one of the nozzles not printing consistently.

This was after around 700 hours, which isn’t terrible, but working with their support is exhausting. I don’t think I’m going to touch it again until winter, unfortunately.

I don’t know if bambu is easier than Prusa. Bought myself a Prusa core one, having absolutely no idea whatsoever what is 3D printing, plugged in, the included filament in, just as the 10 pages manual says, click click, and I made my first print (no internet connection, no wifi, no registration, no app).

Then I installed the app (open source in github) and started using the “cloud” services. I consider myself pretty stupid with such things, and it was absolutely the easiest thing I’ve done in 10 years.

The price is very high though. But at least you OWN the damn thing.

Given how I'm not sure there are 2D printers that really "just work" and don't throw opaque hard to track down errors at random - I actually like open 3D printers that do break, but you can be sure any issue is fixable & you will learn something new in the process. :)

I know it's popular to shit on 2D printers, but other than very often being very slow and running out of ink (or rubber rollers hardening after 20 years of use) - I actually didn't have any issues with them? But then I actually didn't really use them for 20 years either.

Im not sure what problems people are even envisioning having. I got a diy Anet8 that was badly assembled by somebody else years ago that they gave to me for free. I tightened up some fittings and strapped down some loose wires and it still just works. If newer and supposedly better printers were more difficult I would consider them junk, in operation they aren't that complicated of machines. The most complicated thing I gotta do is usually change the print temp up or down 5 degrees for different company filaments.

Last time I checked you don’t have to pay that much more for a Prusa than a similar spec Bambu printer.

And in any case, Bambu’s well-publicized abuse of open source has driven me off of ever using their printers. I know that only nerds care about this, so I hope Prusa keeps pushing to build a straightforwardly better product.

I do the same.

Ender 3 V2 that I paid <$250 for about 5 years ago. It paid for itself on the first print job where I repaired some Samsung stove knobs where replacements were $400 a set.

I'm now considering an upgrade and I'll likely just go with the Ender 3 V3 Plus (bigger bed, auto leveling, still an offline printer) and < $450 for cost.

It's been a fantastic printer for me.

I use Cura, stick with standard settings, use Sun PLA+ for all my prints, and the only thing I really need to do is level the bed sometimes.

marcus_holmes 5 hours ago

I upgraded from the 3 to the 5, and had some great experiences with it. My Ender 3 was such a Printer of Theseus; I think I'd replaced everything except the extruded aluminium frame by the time I upgraded.

But that's part of the hobby, surely? Like, just having a printer and having it print things first time, and never taking it apart or replacing chunks of it to see if that would work better, seems kinda dull to me ;)

Oh, and fuck Bambu. Never touching their shit.

Creality has printers that are straight-up clones of the Bambu printers and are just as easy to use, but they've historically been somewhat okay at working in the open source ecosystem, unlike Bambu.

Prusa is, of course, the gold standard, and their more recent printers are super easy to use, too.

Dusting off my HN credentials to plug Qidi.

If you can afford to pay more for less printer, get a Prusa Core One. I almost did, but at the time the cost would have included four months of waiting, and that was just too much.

But the Qidi Plus 4 has been just a beast for me. It had some growing pains, and the Internet is forever, so if you read up on it you'll see some scary-looking problems involving the heating element which have been completely fixed for more than a year. From everything I've been able to determine, the QC issues with the Plus 4 are over, and the newer printers like the Q2 and Max 4 have never had them.

I think the intersection of "reads HN" and "needs that tiny delta of convenience between Bambu and Qidi" is empty, basically. Qidi are good open source citizens, and you get a lot of bang for your buck, especially handling high-temp filaments. It's _possible_ to print nylon and ABS on Bambu hardware, but realistically you want something a little better.

Also they're cheaper than Bambu. Thought that was worth mentioning as well.

I'd seriously consider the Snapmaker U1 also, but not the K2 Plus. For one thing, Creality has had to be bullied several times to meet GPL obligations, and I don't like to reward that kind of behavior. For another, the Qidi Max4 is bigger, prints hotter, is more precise, and costs less. Pareto improvement on the K2 Plus.

I'm holding out on the Snapmaker because a) my Qidi Plus 4 is a great piece of hardware and at only 700 hours it's got a lot of life left in it, and b) The Prusa + Bondtech INDX is right around the corner. That's probably going to be my next printer. I find the waste and extreme slowness of AMS-style multimaterial too distasteful to invest in, and I think that entire paradigm will end up in the dustbin as tool-changing consumer FDM matures.

Chinese printers, like Chinese drones, Chinese PV equipment, and Chinese electric cars are inexpensive but that's because the Chinese Communist Party loves to pick winners.

They subsidise the living heck out of designated national champions, dump oceans of cheap product onto the international market, kill off international competitors, and then seize control of markets. It is neither legal, nor morally defensible.

Want a printer that happens to not be made in China? Good luck. Pay more, or knuckle under, and accept Chinese control of your technology, and increasingly, what you are allowed to say and think.

I don't think Prusa and Bambu compare well. Prusa printers aren't as cleanly designed as Bambu and they are more than twice the price. I consider them really poor value for money. And Bambu printers aren't clones. The AMS is something they came up with.

Also, Prusa copy from Bambu too. Like their own material switcher (much less sophisticated than the AMS) and the new Core printer is really more a Bambu copy than the other way around, honestly. In fact other brands are copying Bambu too.

I really like them, they are fair to me as a consumer. Spare parts are cheap, there's no consumable restrictions or subscriptions for their cloud service.

And they're really as plug and play as you can get right now. I don't really need that, I've owned printers since the first generation so I know how to deal with issues. But really they happen rarely. The worst I get is stuck filament in the AMS and I found I can prevent that by removing the bit of filament with gear bite marks after it's been through. It absorbs more water then and gets brittle.

Also I've learned from earlier printers not to mix materials in the same nozzle so I switch them too.

No idea about the filament swirchers, but calling core XY designs bambu clones is really funny.

The core XY design that all manufacturers are now centering around has been around long before Bambu existed as a company.

I think the Bambu social contract is pretty clear:

- they benefit from open source software work

- we benefit from their dirt cheap top performing machines

As long as they remain the lowest priced and the best, they can do whatever they want if you ask me. They provide insane social value through accessibility. Before them, it was Creality with the Ender 3.

My problem with Pruša as an European is that it turns us into the equivalent of being a Chinese citizen who can't afford the Temu product they make at work. Their machines are priced more or less only for US export, and not really something most people here can reasonably buy. They even refuse to use injection moulding out of some self righteous principle, which drives the price per unit up further all the while selling less durable machines cause they're half RepRap. I take it sort of as a personal insult and I will never buy one even though I can afford it, I see it as bad value. Like buying a gold plated watch or something.

I just finished building a Core One+. It has a number of printed parts, but it also does have a bunch of injection molded ones, and they've just replaced another printed one with injection molding. Most of it is metal though, with the printed parts mostly used as relatively simple brackets to hold stuff in place that doesn't need great precision, and replacing those probably wouldn't save much on cost. I think these days they do the printed parts thing mostly to dogfood their print farm solution and I wouldn't be surprised if the next generation had only one or two printed parts for bragging rights. I wasn't a big fan of that either, the Mini I got in 2000 had a few critical parts printed and that did impact performance somewhat, but the Core One+ is fine in that regard.

From a hobbyist perspective, I find it's a much better designed machine than a friend's Bambu that recently broke down and turned out pretty much unfixable. Performance is at least on par, but the entire Prusa can be taken apart with basic hex and torx keys, it's highly serviceable and repairable, lots of fairly standard parts, not very highly integrated. I consider that a feature, but that will cause higher sourcing and assembly costs. It's built like a tank, lots of attention to detail, I expect it to last for a long time with minimal servicing.

That also means it's not targeting the same niche as Bambu's printers. That's not a personal insult, that's just a consequence of how things are right now. No European company is going to undercut a ultra high scale Chinese market dominiation vehicle, that's just not happening. Prusa is doing lots of R&D on much lower sales, they don't have the kind of access to Chinese industry that Bambu has, obviously the Bambu will be cheaper even if Prusa tried to compete in the same segment. But once the market domination thing is far enough along I expect Bambu will disallow non-chipped filament, lock everything into their cloud and jack up their prices. That's how these schemes usually end if they work out, but if they did that now, companies like Prusa would see record sales, so they don't do that just yet.

I'm pretty happy we still have some trace amounts of viable B2C tech industry in Europe. Companies like Prusa provide insane social value too by keeping skills and production in the EU. That's something we sorely need more of (not that companies are to blame, but we still do). Not sure how things will play out, and I'm not too optimistic, but perhaps with everyone else going all-in on dark patterns and pumping out disposable low cost crap, there is an emerging niche for reasonably open high-quality products that serve the owner first and don't data mine them for every last private detail.

So it's a problem that their printers are popular, and they can't be bothered to scale their infra, so let's gate everything based on USER AGENT STRING! This is so crazy of an excuse that I don't believe it.

That’s good in theory but there are also plenty of counter examples of companies forcing features and still making it by just sheer brand reputation or market share (HP still has DRM’d ink, Keurig is still going after “hacks”) or just money (OpenAI promised to open source their model).

I’m not saying we shouldn’t shame those companies for not abiding to their words, but there is more to it than outrage. Suing them (or the threat of) might also work here if they really went against the license.

Also, LAN mode is NOT a substitute for the functionality you bought the printer with.

My biggest annoyance is that I can no longer use OrcaSlicer to interact with my printers (e.g. sync filaments) and start prints remotely. I am still very annoyed at Bambu Labs for this stupid move, as it directly impacts my usage.

What most people seem to be missing in these discussions is that some of us have printers in remote workshops, not next to us. So all the "LAN" or "Developer" options aren't great, especially if you have to pick between those OR the cloud.

I have no issues with OrcaSlicer and interacting with my printers or starting prints remotely as long as I have LAN and Developer mode turned on. The only catch is that you need something like Tailscale set up for remote printers so you can access them over your "local" network. You can also get remote management/monitoring on your phone with apps like Openbu or Lanbu.

I am an outsider on the details of the Bambu software requiring users to go through their servers in China and the closing of their software.

Still I suspect it is about spying in wartime, Bambu printers are at the core of the Ukrainian war effort, the main reason even Ukraine is winning since januari 2026.

First China prevented Ukraine from using any of the drones that they sold in millions to Russia while exercising the built in kill switches in Chinese drones used in by Ukrainians.

Suddenly Bambu, another Chinese company started listening in on the 3D printing on a massive scale in secret factories all over Ukraine that make the drones to replace the Chinese drones. Very suspicious.

Whatever is the reason Bambu locks down software or firmware on their 3D printers, now is the time for programmers to change the situation. We need to put up money like Louis Rossmann did [1], not to fight legal battles but for a assembly language programmer to reverse engineer the Bambu firmware and make a free and open source version.

This firmware replacement will cost a couple of months to write so we all should send that programmer a little money so he/she can release it for free.

A free Bambu firmware will allow the Ukranians to continue producing another few million drones and save over a hundred thousands lives by ending the war.

Now is the chance for us outsiders to help Ukraine, by freeing Bambu firmware.

[1] https://www.youtube.com/watch?v=qLLVn6XT7v0

P.S. I would be willing to do the reverse engineering but I would need at least 35 euro per day (to eat) to build a new firmware for all Bambu models from scratch. I would need a few different models of printers on loan for a few weeks to test the new firmware. I estimate it would take 5-9 months to rebuild firmware for all models from zero and release it. Maybe Rossmann and Geerling could use their influence and coördinate this freeing of the firmware?

I just emailed Rosmann and Geering to see if we together can free the Bambu firmware. Anyone who wants to help, please contact me trough my HN profile.

I'm not up to date with their latest printers, but the Bambu printers used during this timeframe have easy ways to enable LAN only mode. You can leave it disconnected from the network entirely and use an SD card, too.

The app lets you enable root access and install firmware mods. There are multiple efforts to reverse engineer the firmware.

Or just put your file on an sd card and plug it physically into the printer?

In practice Ukrainians have long moved to custom built drones for pretty much everything.

Picking up 3D printers that don't spy on you, modding them or even building custom ones is much easier than designing and building millions of custom drones, so I am sure they solved this long ago.

Like, really - a FDM printer is just a MCU board with a bunch of stepper drivers, a power supply, some frame, motors, thermistors & heating elements.

bityard 18 hours ago

I'm an open-source advocate (some would say zealot?) but I ended up buying a Bambu P1S a few months back because my research indicated that there were ways use it normally without creating a Bambu account, or using their slicer, or having to send all of your prints through their servers.

I don't have my notes in front of me, but I managed to do all of that with hardly any trouble at all. IIRC, you only had to change one setting on the printer itself, and optionally block the printer from Internet access via the firewall to prevent automatic firmware updates and telemetry. I have only used OrcaSlicer to tweak my models, mess with parameters, and send the prints to the printers.

So other than Bambu getting all heavy-handed with a legitimate open-source fork of their slicer software (which is definitely not okay), I'm not sure I'm clear on what the kerfuffle is about. Are their printers now MORE locked down than before? Or maybe only certain models?

switchbak 18 hours ago

"you only had to change one setting on the printer itself, and optionally block the printer from Internet access via the firewall to prevent automatic firmware updates and telemetry" - "only" is doing a lot of work here. Yes, this is easy for us, but that part alone is beyond most users.

I have a P1S myself, and I find Bambu to be a strange company. They're one that has benefited tremendously from OSS while sometimes violating both the ethos and licenses.

They specifically engineer it such that your prints need to go through an intermediary even when it could send it right to your device on a simple network. That'd be like a laserjet routing through the cloud instead of going to your device. With nothing much in the way of encrypting your designs and protecting your data, it feels like this was done on purpose. Given the shameless track record of many (most?) Chinese companies on IP, my assumption is that they're mainly doing this to steal designs. The juxtaposition of their poor track record on OSS, what seems like a shady approach to privacy and IP protection, and the aggressive legal posturing - all sum up to what I think is a very untrustworthy organization.

Luckily my designs are in the "look at this trash" territory, so I don't have anything to worry about, but I certainly wouldn't use this for important work.

pimterry 18 hours ago

As far as I can tell, they're just objecting to use of their cloud service. You can fork their software and use it with your own printer just fine, they just don't want you to use it with their cloud service, which its own terms of service for access.

I think it's an odd hill for them to die on, but it's not a totally unreasonable position - the cloud is other people's computers, other people can have rules about what you can do with their computers. Just because a client is open-source, doesn't mean you're allowed to use the server.

If you're using developer mode running everything locally (or remotely over your own VPN, like the author here) then I think this makes zero difference.

amiga386 16 hours ago

They're objecting to use of their cloud service, and they're also disabling local-only mode thus forcing use of their cloud service, and their software is required to be AGPL (because that's how they themselves received it) so they're required to allow you to clone it and modify it but they just don't want you to.

It's "I would like to take this free software so I don't have to write it, oh and by the way I want to make everyone dependent on me now for enshittification reasons, so kindly fuck off and let me use this software just by myself. I take, you no take. Understand?"

Before: user can print via cloud or locally with custom slicer at the same time easier.

Some time in 2025: firmware updates make user choose between cloud XOR locally. Enabling local mode allows using custom slicer, but disables cloud printing or monitoring. Folks were up in arms because they wanted both, and openness.

Latest fork: a specific new custom slicer impersonates UA to submit print via bambu cloud, so it gives the pre-2025 experience.

Bambu sues this new fork. Actual OrcaSlicer working locally is fine.

dangus 18 hours ago

Bambu didn’t sue, they sent a cease and desist letter. Just to be pedantic.

I don’t know what the fuss is about. This whole issue has nothing to do with the open source ecosystem.

It has everything to do with the part where Bambu does not authorize 3rd party programs to contact their cloud servers.

I totally agree that Bambu has their head up their ass here, but still, it’s not an issue that would make me want to choose another inferior or more difficult to use printer at this time.

I own a Bambu printer precisely because it’s the iPhone of printers. It’s a tradeoff.

If it ever enshittifies to the point of becoming a paperweight I’m personally not that worried about it. I paid under $300 multiple years ago for this printer. I know that’s not nothing and I don’t want to be wasteful but it’s not something I’ll be particularly upset about. It’ll be Bambu’s loss when I don’t buy their next products or when I stop buying their replacement parts and filament.

simplyluke 16 hours ago

I'm in a similar boat to you. I understand the current drama, but for my intended use case (an occasional-use tool sitting on a workbench in my garage) LAN mode has been fine and entirely removed from the drama.

I don't want an open source slicer sending prints through their cloud services, because I don't want their cloud services. The value of being able to check on a print or start it from my phone is near-zero. I shoot it off a laptop in my office and check on it intermittently during the print from that same laptop. This has worked fine to-date on my machine, but the concern is clearly that Bambu's corporate interest is not in that use-case, it's getting as much of the ecosystem in-house as possible. They want to control the model side via markerworld, and have everything flow through the cloud.

One doesn't need to assume bad intent, there's pretty clear financial and UX incentives here that mirror a lot of Apple for example. But I don't think I'm out of line for not wanting to move towards that world under a company with Chinese ownership and in an environment where many western lawmakers are pushing for strict control of what the machines can be used for. It's a lot easier to implement DRM, copyright protections, and restrictions on what can be printed in a cloud-only world than one where open source software is sending gcode to a local printer.

I've got no need or intent to replace my machine, but the next one likely won't be a bambu. They're not the only ones who are now making a machine where it works as a tool and you don't need to have 3d printing be your hobby to be productive with it.

GZGavinZhao 18 hours ago

My understanding is that you got your printer when the firmware was not blocking you from doing all of that. Right now if you want to remote print (and don't want to do it via sending models to Bambu Cloud), you can get away if you enable LAN only and developer mode. However, what if the newer firmware forces you to create an online account and connect to Bambu cloud to do the setup? What if Bambu decides to limit the features you can use if you print using a SD card? It has been quite a worrying trend, and now the company is trying to legally threaten an open-source developer building on top of Bambu's AGPL code trying to make remote print without going through Bambu servers possible. Other ppl more knowledgeable on the issue, please correct me if I'm misunderstanding the situation.

I bought a Bambu Labs A1 Mini. It cost $199, on sale. I plugged it in and started printing excellent prints.

Previously I bought an Ender printer for around the same amount. Never did get it to work. I'm not an engineer or a mechanic. I have other technical hobbies, astronomy for example. I tried making a telescope mirror with results similar to the Ender printer. I buy ready made telescopes, not telescope kits.

I have immense admiration for those who can and will make telescopes and 3D printers. I'm very interested in the base technology. But when I want to print something, or look at a faint fuzzy, I just want the system to work.

(Interestingly, I actually like star hopping, the process of finding an observation target with a finder scope and star charts. Go to telescopes have no interest for me. Go figure ...)

To me this seems like a failure of the U.S. corporate/economic system. We should be able to make a 3D printer that simply works. We should be able to make a drones that work as well as the DJI drones. (My understanding is that Bambu Labs was started by a group of former DJI engineers.).

I don't have any solutions here. Not buying a Bambu Labs printer means I don't get to print things in 3D. I would pay more, but whenever I look into the various alternatives that I'm assured are turnkey, they turn out to not be turnkey. And if my Bambu printer breaks I can generally buy a new one cheaper than paying someone who knows what they are doing to fix it.

I'll admit this kind of offends my geek sensibilities. I actually agree, at least emotionally, with Geerling. But I also agree that the U.S. military industrial complex should be able to make excellent consumer facing 3D printers.

If I were doing commerce with the 3D printer I almost certainly would be using something else. Maybe. For what its worth, I'm basically printing out puppet mechanisms and art figures. Occasionally a wall hook or missing part for something that I happen on a STL file for.

Here's what I don't get. How is infra load any different between someone using their slicer build, and someone using their code in another slicer (or a fork)? It's still (ultimately) the same human making the same requests. If they can't handle the load then the solution is to obviously carefully manage the supply of the printers, if your infra is incapable of handling more than 3 users (accurate figure going by the tone of their blog post), then don't have more than 3 of your printers in the wild at any single time. Problem solved.

daemonk 19 hours ago

I don't disagree with Bambu from an operational standpoint, but disagree with their handling of this.

They are offering a cloud infrastructure that allows users to remote control the printer via their software. If they don't want users to use a non-approved software to access their cloud, they should just build auth around it and explicitly tell people that. The accessibility for users to utilize the printer without going through official software and cloud is a whole other can of worms of course.

This whole fiasco could have been avoided by not being so confrontational, giving their user base ideological ammo.

The license isn't the issue. It's the User Agreement. Bambu is claiming that the fork is allowing, enabling, (and/or promoting, encouraging, etc) users to violate the agreement with Bambu to not use their cloud with third party software.

I'm fairly certain user agreements have been used for suing makers of game cheats and other similar things. Certainly in the industry I work in, there was a company making third party software and integrating it with the industry standard tool without going through the official channels, which caused people to violate the user agreement when used.

Like when you think of the App/Play store lockdowns, the new ReCaptcha attestation stuff, and other things that have a more authoritarian angle to it as of late, you can at least see how it happens: most of their consumers aren't technical and don't even know how to argue against it or why they should care.

With Bambu on the other hand, I'd think a good portion of its customers do actively care about this kind of thing. 3D printing just doesn't have the same market reach as computers and smartphones.

Also, it seems to me like there's eventually going to be a turning of the tide on all of these pushes (app stores included) and companies that are making these kinds of moves aren't seeing that writing on the wall.

Good article, but I'd like to ask about two small technical details (I've used Bambu before, but I'm not very familiar with the 3D printing ecosystem).

1. OrcaSlicer: so it's a fork of Bambu's official client, Bambu Studio - but it apparently still goes through Bambu's servers for printing? How exactly does that work? Does it also "impersonate" the User-Agent, and Bambu was okay with that?

2. OrcaSlicer-bambulab: if the goal of this fork-of-a-fork is to bypass Bambu's cloud servers, why would it still need to "impersonate" the UA and communicate with Bambu's servers (as Bambu claimed)? Wouldn't the whole point be to avoid doing that in the first place?

nyrikki 19 hours ago

Orcas Slicer is a fork of Bambu Studio, which is a fork of PrusaSlicer, itself a descendant of Slic3r.

Orca Slicer was forked to improve usability and features, not to get around any cloud printing requirements, Bamboo added those later and removed the ability to print locally.

It has to impersonate to transfer a gcode file locally, which is another open standard.

Bamboo restricted LAN printing, that is the issue.

I finally got to the bottom of this; there is a cloud-based RPC method called `bambu_network_start_local_print` where Bambu's Cloud would authorize a print using (ostensibly) only locally transferred data. The goal of this project was basically to pretend to be the Bambu plugin in order to authorize this method, which is otherwise locked behind Bambu's auth system.

The alternative is to run the printer in LAN mode (which OrcaSlicer has always supported) where the client connects natively over MQTT, but after Bambu added their cloud authentication, this requires putting the printer in Developer mode and severing the Cloud features.

Bambu has the slicer (orca, bambu) download a plugin (owned and written by bambu, closed source.) which is what the controversy is about.

misnome 17 hours ago

Orcaslicer is a perfectly legal fork, and in the past downloaded the official (closed source) binary blob to talk to the servers.

Bambu doesn’t want to serve people who reverse engineer the new (again, closed source) binary blob.

All of this being about the AGPL is just disingenuous ragebaiting.

One aspect of this may be Chinese laws, which I am assuming if they don't already require the ability to monitor or even censor what gets printed, they will soon. Even in the US we are starting to have legislation related to blocking firearm component printing, but this doesn't necessarily mean central servers do it or have access to everything printed. Yet.

I think the primary problem is actually more than just Bambu's behavior, it's that China is an authoritarian country, and most of the population not only accepts the idea of central servers monitoring and "moderating" behavior but largely may embrace it as a sensible thing to do. It's probably beyond Stockholm Syndrome to the point of much of the culture genuinely not completely even understanding the idea of why privacy and personal control is important.

Much of the United States is so far on the other side that they can't begin to understand the position Bambu is in. Large companies in that country just do not have the option to allow their users to bypass censorship and monitoring.

I do think it's actually great that this type of issue gets in everyone's face though and it's great people are fighting back. But realize that the problem is deeper than one company. It's the whole type of government and attitude towards it and technology.

Here is my perspective as someone who has not started 3d-printing yet, but is interested to give it a try:

I'm a confused about the whole "3D printer sends prints to its manufacturer's server" issue. Because I wouldn't want to connect hardware device like a 3D-printer to a network in the first place.

Can I buy a Bambu Lab printer and just never hook it up to any network?

Will I be able to print from sd-card just fine?

Can I update the firmware from an sd-card?

If these two are possible, I would not have any problems with such a device. If they are not, I would not even think about getting such a device.

And when it comes to slicing software: Can I use any slicing software and all I have to do is load the hardware info of the Bambu Lab printer I want to use? Or do I have to use Bambu Lab Studio or a fork like Orca Slicer for some reason?

And while we are at it: Does command line slicing software exist? I wouldn't want to dabble with a GUI. I would want to define the parameters of a print job in a yaml or json file and then slice it like "./slice.sh config.yaml myobject.stl"

CarVac 15 hours ago

You hook it up to the network to use monitoring features like a remote camera view to make sure your print is going smoothly.

SD cards work but it's extremely less convenient than just printing straight from the slicer.

You can use any slicer you want but Bambu wants only their slicer to directly connect.

CLI slicing is not something you want in general. Visual confirmation of the toolpaths is very important to making prints as successful as possible.

I'll play devil's advocate. What is Bambu Lab's motivation to provide lifetime free cloud services for a onetime revenue transaction? They could demand a subscription. But they probably know for casual users this would be unwelcome. They could seek to monetize via other means like ads or cross and up-sell. Third party clients are a risk to these.

I don't see the ground the OSS community are standing on to demand Bambu provide free services.

Serious question: why not just release whatever you want but not tie it to your identity? Bambu demands OcraSlicer make changes under threat of litigation? OK, cool.

Hell, post a notice that they were compelled to remove the feature, and that they're thereform removing the release x.y.z, with the sha256 hash of "...".

Now OrcaSlicer has complied, and the community has an semi-official way to make sure that the commits that were removed aren't modified when they get them from other sources.

IDK anything about 3d printing, but is their online service so complicated that people can't create an open source self hosted alternative? If they can already take the LAN version and send spoofed requests to their servers, they can do the same to a new fully open server.

Surely people can check the traffic and build a server to answer similarly, no? Or is this much more than job management?

Maybe this is impossible and I'm talking out of my ass, but for me it seems like a perfect opportunity to completely remove the problematic party from the equation.

New product launches by them feel less exiting (I don't want/need laser engraving capabilities in my 3D printer) and I agree with other commenters that these days, there are good alternatives. Unfortunately I have to say that wasn't around the time I bought the printer. When you just wanted to print things without making 3D printing a hobby, their machines were a no-brainer!

But yeah, bye bye Bambu Lab.

Same! I was burned by Chamberlain, twice. In my case I had bought a $40 retrofit device (it connected to the MyQ cloud and simply used RF to emulate a remote to open any brand of opener).

First, there was their debacle where they broke HA connectivity just for fun, meaning I couldn't use HA or Apple HomeKit anymore. Then, after a pretty routine reset of the opener (I needed to clear out some old remotes and re-learn them) I found that in some recent update of the 'app' or whatever, they'd deleted my brand of opener from their supported list, due to some IP dispute of some kind, leaving it unable to learn the same remote it had learned the year before. So, as peeved as I had been to have to use their ad-laden app, the myQ device itself was completely useless to me.

Never again.

Irony is I just moved to a house with a brand new MyQ cloud-connected door. I bought a RatGDO anyway and will never buy any of the devices in the myQ ecosystem, even though some look attractive. Closed system on purpose = never buy.

I bought one a few months back when it was weirdly cheap (£260 delivered!) and it's been really very solid. I've only had a couple of issues:

1. One of the bed temperature sensors reported a fault, this was a loose connection and took about 10 minutes to open and reseat, which was nice

2. I sometimes get an error in Chinese that blocks a print and requires pressing a continue button on the touchscreen. I've tried translating this and I have no idea what it's on about, so if anyone does know what it is then lemme know. Doesn't cause me much trouble though

Overall I'm really pleased with it - it's pretty much a bargain. Mine has never been connected to the internet and very rarely has print failures (and they're nearly all my fault when I have had them). I've ordered the multi-filament addon which they've just announced, and I was pleased to see them offer that as an upgrade for purchasers of the first model.

scottbez1 19 hours ago

I have the original CC. It’s a fine budget machine for single color - plenty fast and good quality prints.

They rubbed people the wrong way launching the CC2 with multi-color support before they developed the multi-color add-on that was promised for the original CC. I didn’t plan on multi-color with the CC, so that didn’t personally bother me too much.

I recently got a Snapmaker U1 for multi-toolhead prints and love it so far - much less waste than a filament changer and I’m using it for more exotic prints like a mix of conductive and regular PLA in a single part that wouldn’t work well in a filament changer single toolhead printer.

And I still use my CC for occasional single color prints (recently it’s been dedicated to TPU but I’m probably going to move that over to the U1 so I can do “over molded” TPU+PLA prints).

In short, if you’re willing to spend more I’d highly recommend the U1 if you know you’d benefit from the toolchanger. CC is probably a fine budget machine but there are a lot of other similar budget corexy machines to consider these days as well (I got CC when it was groundbreaking for features at its price but competition has caught up by now).

That said none of this is surprising. Bambu Labs have been very candid about their playbook which is following Apple's lead. They want to be the Apple of printers, a very walled garden with high integration good UX and not a lot of freedom because they want to tightly control the full experience.

And that is going to alienate a lot of people and endear a lot of others. The only reason they've even paid lip-service to open source or open hardware is simply to get a foothold in an industry that had strong roots in that area. Now that they're a more established brand we should expect them to start bricking in the garden and adding controls.

Fortunately I think they've been a net-good for the printer landscape, they shook things up pretty hard and I think there's now more competitive models from other brands.

What did `orcaslicer-bambulab` actually do?

My understanding is that right now, you can run your printer in LAN or USB mode without Bambu's cloud, and this is supported natively by OrcaSlicer (or any slicer using USB), but you lose some of the Cloud monitoring features.

You can also use Bambu's cloud with their Cloud Connect app and gain those monitoring features while using a third-party slicer, but at the expense that you send your prints through their cloud.

Or, you can use Bambu Studio and get the "fully integrated" experience.

My understanding is that this plugin just replicated their Bambu Studio communication with the Cloud, and that it _enabled_ you to send your prints to their cloud, not _disabled_ it. Is there something I'm missing that made this valuable? (ie - did it do some hybrid where it could hack in the Cloud monitoring without sending the prints through the Cloud?) Otherwise, I think what Bambu are doing are distasteful but I don't understand all of the Chinese espionage hand-wringing or "stealing our files" commentary around this.

EDIT: I finally got to the bottom of this; there is a cloud-based RPC method called `bambu_network_start_local_print` where Bambu's Cloud would authorize a print using (ostensibly) only locally transferred data. The goal of this project was basically to pretend to be the Bambu plugin in order to authorize this method, which is otherwise locked behind Bambu's auth system. This makes more sense.

I'm supportive of Jeff's general philosophy towards open source, but this feels a little disingenuous. Did Bambu mishandle the situation? Absolutely. But we need to stop vilifying companies for being cloud-first. The reality is that 99% of their users set up the printer and app using the cloud service. It's easy and convenient. The slicer is still open source, and you can still use their printers without the cloud. (Yes there was some fighting after their security issue in 2025, but they did put in an effort to maintain compatibility with third party slicers even if it was misguided and/or out of touch.

Bambu has every right to restrict or limit how their cloud service is used, even if they do it in a completely insecure and trivially reproducible way (a user agent).

I'm curious from a legal perspective - the user agent in the Bambu slicer is AGPLed, so copyright wise it seems anyone could put it in their own slicer too. Nonetheless, something feels wrong to me about saying you're a Bambu slicer when you're actually not. Bambu is going after it because of the user agreement, but is there any other legal standing for complaint?

airport_barfly 16 hours ago

I think it's more disingenuous to call "trying to ruin a guy's life" "mishandling the situation". Also

* user agent spoofing has been common practice on the web for decades * Bambu's customers were bait and switched here. They bought a printer that works locally, and Bambu wants to remove features from the product they paid for. And it's the _customer_ who's actually running this slicer and impersonating Bambu.

Imagine if you bought a car with Carplay/Android Auto. A year later, the manufacturer pushes an OTA update that locks Carplay behind a subscription. But they have terrible security, just trusting the car itself to say if it has a subscription, so you use use pirate software to bypass the restriction and get free Carplay.

This is a far more financially damaging outcome for the car manufacturer, closer to stealing than user agent impersonation, but I would still argue that its morally justified. Consumers should have a right to fight rug-pulls, especially a physical product. This behavior from companies would never have been acceptable before the internet.

Part of me thinks that the particular kind of enshittification we've come to see with devices, where something that certainly needs no cloud has a hard cloud dependency baked in, is partly an accident of the networking environment everything has grown up in.

When broadband and then especially Wi-Fi caught on, using NAT was so practical, solving both the "how do we properly configure a firewall to only route good traffic" problem, and the "we don't have enough routable IPs for every smart toaster or baby monitor to get one."

Only after this reality and assumption had been completely baked into every home network and the devices used to build those networks, then we started to see IoT devices, which really benefit from remote access. Companies added cloud because it was the only way to make that work - and most of them didn't want to implement and support a different protocol for LAN usage when that wouldn't sell any more devices.

I wonder if we had started out with ipv6 before the wi-fi boom happened, and every device had a routable address, and wi-fi routers always had good firewalls, and UPNP had not launched with immediate security issues... I wonder if we would have seen much more direct connectivity enabled by companies who given the choice, would rather sell a device that didn't need anything from them to support, instead of a device they're obligated to run servers for (at least for a few years).

This is not necessarily true. There are technical solutions to preserve privacy, end to end encryption being a very common one. That being said, Bambu strikes me as a very competent 3D printer designer, but not so much a competent software designer.

> rental model

I don't think this really applies to a hardware company selling 3D printers. You can always still use SFTP or SD cards to print. A big selling point for them is the ecosystem and being able to, for example, find a model on the app while you're on the road, send it to your printer, and have it be done by the time you get home. If this weren't cloud enabled, most of their customers wouldn't be able to get it to work because things like VPN or tailscale are well beyond them.

Every step they take pushes them closer to fully locking their printers down to be either subscription based or use their (always out of stock) filament.

To me, this looks like state pressure rather than a normal business decision. I cannot see a convincing reason for it otherwise. If these printers are used in professional settings, users may be unknowingly sending prototypes, designs, and internal project data to China. That kind of access would be extremely valuable, especially if the company can identify the buyer, their location, and their field of work. Given the relationship between Chinese companies and the Chinese state, corporate espionage seems like the most plausible explanation.

Don't forget that you are having the cloud hosted services generate and send executable code to a device inside your corporate firewall. I can see all kinds of potential issues corporate security would have just based on that fact alone.

Do such people really exist? Are there actually people who are comfortable blindly starting a robot in their home, with a part that heats to 150 C, and then hope that everything will work out and when they get home the part will be waiting for them, instead of the firefighters?

jrflo 19 hours ago

Yes, very common use case. I print things remotely from home on the printers at the office all the time, as do many of my colleagues. Probably not a common use case for people with at-home printers, but if you use them professionally people do it all the time. That said, you probably don't want bambu's cloud if you're working on protected IP...

Closer to 200C. But the gantry constraints movement, the 200C nozzle can only really touch its holder, the print bed, the filament and some metal or silicon cleaning surfaces. None of those are flamable at those temps.

Maybe if it knocks itself down to the ground? But I worry much more about faulty wiring or stuff like that. And that's more a function of the brand and model

m4rtink 15 hours ago

It could be enough if the nozzle just stops moving while touching the model being printed - based on the type of material, it might start burning.

And if you want to be outright malicious, you can disable maximum temperature control and do the same with much hotter nozzle rammed into the model - and even print an extra burnable model when you are at it!

Or count on the power supply or the wiring catching fire instead due to overload.

colechristensen 19 hours ago

All of the fires I've heard about 3d printing involved sketchy power supplies in some of the printers or DIY builds out there. Thermal runaway protection is really easy code to write and very common in firmware and the thermal design of the heated parts makes it hard to get there.

Not saying fires don't happen that way but let's say it's a failure mode that is a challenge to achieve intentionally much less accidentally.

I would have never done this 10 years ago with the garbage printers that were pieced together like science projects rather than finished products.

But a modern enclosed bambu printer is a much better engineered device. Bambu is mature enough as a company that they've issued formal recalls for device issues before. This would never happen with the aliexpress specials that used to dominate the market.

Bambu printers (and other reputable modern printers) are being run unattended at scale all the time without issue.

awakeasleep 19 hours ago

That isn’t a significantly different risk from how you are required to use a FDM printer, regardless of circumstance.

Prints regularly take ten+ hours to complete. No one is vigilantly guarding their printer during this time. Fire spreads so quickly in a house that a smoke alarm is often just a signal to get out, you don’t necessarily have the time to grab a fire extinguisher and put it out.

And how big is the risk, really? The materials that you use do not ignite so close to their melting point.

m4rtink 15 hours ago

We built an enclosure fort our printers from a metal storage rack & added active ventilation that suck out any fumes outside the building. Still, you need to physically get there, check the bed is clean & start the print manually.

There are are also regular software checks for overheating or thermistor wiring failing & we know they are there and are enabled as we built the Marlin firmware ourself from source (which is quite easy once you properly configure it). Not to mention we are sure we are the ones in control over the firmware.

We also have a bunch of web cameras watching the printers print that we can monitor remotely.

The main board of my 3D printer short-circuited and caught fire once. I don't know what would have happened if I wasn't around, but I'm not leaving my printer running on its own without supervision.

Kirby64 19 hours ago

3D printers aren't the fire hazards of yore. They're quite reliable, fused, with multiple interlocks for various conditions (mainly around heating not matching expected rate) that will kill power.

The main potential problem these days (in my view) is whether a print finishes without crashing or delaminating from the print plate, which also has workarounds... but that's only potential printer damage, not a fire.

Pretty common for us to leave the printer unattended. The prints are 8 h or more at times and I’m definitely not watching the device. During that time I might be asleep or out of the house. I’ve never actually started a print from outside but that’s not from a safety standpoint just I’ve never needed to.

At worst the sprinklers above it will wash it but that’s in a catastrophic instance.

My P1S has a camera built into it. If the print begins to fail, I can stop the printer and turn off the heat immediately before anything spirals. Very easy and convenient to remote control from my phone.

Does your house have an HVAC system? Water heater?

Ccecil 19 hours ago

I would never compare an inexpensive 3d printer to a household device which is designed to last decades.

It is closer to a toaster or an oven than a water heater or HVAC.

Also...my last lease specifically said that I was not allowed to use the washer/dryer or oven when I was not home. So it is not a stretch to believe that the property owners will use those types of agreements to go against you when the insurance company denies your claim (this does and has happened with 3d printer fires).

All that being said...I have run 135hr prints unattended on my printers (not bambu). The risk may be low but it is not zero and it certainly higher than a water heater or HVAC.

I own a H2C and have been a huge fan of bambu for a few years, full disclosure.

I don't really see why everyone is up in arms about this. You are able to print in LAN mode or directly through USB drives without going through bambus servers.

Their slicer is open source but it downloads a plugin once you launch it if you choose to which is closed sourced that interacts with their APIs.

Someone reverse engineered the plug-in and put it into orca slicer and then claimed that the plugin should have been GPLed to begin with which I find dubious. I don't really see it being much different than downloading closed drivers on Ubuntu but I'm also not a open source lawyer.

To me, the problem with all of this is that it seems strange to want the plugin when bambu will just shut off their resources to unsigned versions of the network plugin if the orca slicer dev got their way.

I'm open to being convinced but I just don't think the cross-section of people who want this would actually want prints going through bambus cloud so this effort really feels vain.

It also feels like bad framing as well because every post I see about this thing really tries to blur the line and claim this plugin and orca slicer are one and the same.

The plugin wasn't reverse engineered. The interface with the plugin was AGPL so you can freely use it in any other AGPL software.

> Someone reverse engineered the plug-in and put it into orca slicer and then claimed that the plugin should have been GPLed to begin with which I find dubious. I don't really see it being much different than downloading closed drivers on Ubuntu but I'm also not a open source lawyer.

The GPLv3 specifically was written to address a problem called "TiVo-ization", which is when a hardware vendor uses some trick (DRM, proprietary blobs, whatever) to prevent users from actually running modified versions of the software.

The AGPL, the license of this particular software, extends the GPLv3 with protections for users of network services:

> Simply put, the AGPLv3 is effectively the GPLv3, but with an additional licensing term that ensures that users who interact over a network with modified versions of the program can receive the source code for that program. In both licenses, sections four through six provide the terms that give users the right to receive the source code of a program.

https://www.fsf.org/bulletin/2021/fall/the-fundamentals-of-t...

And on TiVo-ization: https://en.wikipedia.org/wiki/Tivoization

The Linux and proprietary drivers situation is more complicated, but proprietary drivers on Linux are generally restricted to interfaces that Linux chooses to expose to them for that purpose. But the Linux kernel seems to take a narrower view of what constitutes a derivative work than was likely intended by the FSF in writing the GPL. Under a "traditional" reading of the GPL, those proprietary drivers are meant to be illegal. Whether some or all of the linking done by proprietary drivers in the Linux kernel is really allowed by the GPL or not is somewhat untested, I think.

Doesn't it sounds weird to you? I mean, what the reason they have to blur the line? Are they just clueless? Or maybe they fight for some political reason, like an anti-corporate stance, and Bambu is just a convenient target for them?

I'm asking, what you think of them, because I can't understand you. Your take on the conflict is incompatible with behavior of the people opposing Bambu. Or rather it leaves no good explanations for their behavior. When I notice it, I start digging, because if the situation doesn't have a good explanation, it means I do not understand the situation. But you just accept your understanding, so you have some good explanation for people's behavior?

It is very dubious way to subvert GPL, even GPL2, not to mention [A]GPL3.

It was discussed many times that you cannot have close-sourced plugin for GPL host program, as loading plugin is linkage and it is covered by full GPL (only LGPL has linkage exclusion).

This is in no way equivalent. You can't sync filaments, you can't monitor printers in your slicer, you can't monitor prints from your phone. This is like going backwards at least 5 years.

I find this shallow take really annoying, as it tends to derail most discussions ("you have LAN mode, so what are you complaining about").

colechristensen 19 hours ago

Regardless of the license if they only want their own software interacting with their cloud API, I don't really care because USB and LAN are there. That is ample ability to interact with the machine.

socalgal2 7 hours ago

Wow, I'm surprised how much I disgree with the HN consensus here. This feels to me, (almost) entirely in Bambu's side here. I'd say their security sucks and they should have implemented some kind of secure accounts so random person without account can't interact with their service like 1000s of other services. But, otherwise, they're right that you don't have a license to their service, only to the AGPLed software.

dperfect 19 hours ago

Bambu Lab has made plenty of mistakes, but I don't think this is one of them. And I'm a big supporter of open-source software.

Their cloud infrastructure obviously has real costs associate with running it, and I don't understand why any software other than their own should be entitled to use those resources.

If you buy something and then significantly modify it, you generally tend to void the warranty - and that's not because companies are just greedy; there are real limitations when it comes to a company's ability to support the endless ways a product could be modified.

Publishing something as open-source does not imply that you must operate an optional-but-complementary service at a loss for charity.

dns_snek 19 hours ago

> I don't understand why any software other than their own should be entitled to use those resources

That's not a genuine argument, nobody "feels entitled" to anything. Bambu made a deliberate choice to architect the product this way, deliberately placed themselves in this gatekeeping position, and they're deliberately working towards removing any other form of access to our hardware.

dperfect 19 hours ago

> they're deliberately working towards removing any other form of access to our hardware

Maybe I'm mistaken, but I don't think that's what is happening. They aren't doing anything to block OrcaSlicer or any fork from working with the printer using LAN-only mode. It's only if you want to use Bambu Lab's servers for essentially a remote-access solution (which, by the way, kind of defeats the privacy-oriented purpose of running some of these forks) that they're saying you should use their own software.

Thought experiment: the core of macOS (Darwin) is open source. Does that mean everyone running Darwin or a fork of it should be able to use iCloud services for free?

All this outrage essentially sounds like "since Bambu Lab's slicer is open-source, the open-source community should be able to point any slicer at Bambu Lab's servers to get free remote monitoring services". And I don't think that's right.
