For current owners who want to avoid Bambu's servers entirely, consider LAN mode with OrcaSlicer and this open source reverse engineered networking plugin: https://github.com/ClusterM/open-bamboo-networking
I have verified that my P2S in LAN mode never attempts to make external connections at all (blocked it anyway, of course) and OrcaSlicer + this plugin never attempts to connect to any of Bambu's servers.
My P2S is easily the best printer I've ever had, they really do make incredible machines, it's a shame they have created this ridiculous situation just to (as far as I can tell) collect telemetry.
I think the Bambu case is a good one to litigate the AGPL but perhaps should start in the Court of International Trade. That court has the power to block imports as part of a TRO which would shut down a lot of their revenue from the US at least. Doing something similar in Europe would also help apply pressure. Takes lawyers and money though, of which there is certainly not enough of the latter.
Not to be too glib here, but its one of the paradoxes of "free software" which is there isn't any money generated by the licenses that keep it free. Where as "licensed" software has a revenue stream that is used to enforce the license against people who fail to honor it. The FSF can only do so much with their budget here.
The article says the SFC had a fundraiser and raised over $250,000 to hire a lawyer.
There's a confusing part of the article where he says that what he believes is a violation is something that a judge isn't going to care about. I don't know if he's implying that the judges aren't capable of interpreting the AGPL properly, or if he's admitting that the legal argument isn't as solid as they thought it was when they started. It's a confusing thing to say next to the broad claims about violations.
That confused me as well. I interpreted as judges not having (much) precedent and potentially unable/unwilling to interpret along lines of the license intent. But that’s what courts in this process are there for IMO. If a well written license and a good case, then you need to start somewhere to set precedent.
We just purchased a brand new top of the line Bambu with all the accessories, only for it to be defective on arrival. Their front panel display uses such thin fonts, it makes it almost impossible to read without glasses, and their error codes just send you in infinite loops that make you want to pull your hair out. They really spin themselves as the end all and be all to turn key professional 3d printing, and the reality has been anything but. We are currently waiting on a new part from China that will show up when whomever knows and at best, and all they could offer us a minor credit towards spending more money that doesn't even equal an hours pay.
I wish I could talk better about them, but what a let down. I really hope someone really figures out how to put the screws to them over this GPL violation.
That hasn’t been my experience, for me their software and hardware makes them the Apple of 3d printing. It’s something my mother could use, and everything works out of the box and is simple to maintain. The H2 series is awesome
It's been pretty weird and disappointing to see the way Bambu has taken over with these practices.
If you go on social media where people are talking about 3D printing, a lot of folks are not developers and don't know anything about software licensing. It is hard to explain this problem to them, or why anyone should care. Meanwhile for many of these people, Bambu is totally synonymous with 3D printing.
Prusa has attracted its own valid criticisms, but I think they are closer to being right on these issues. They can't compete with Bambu on price.
Haven't these (A)GPL violations been there for most of the company's history? It's the context around them that changed.
While the ecosystem was open few people cared about the network plugin, and apart from that plugin the Bambu Studio slicer is open source. Similarly there was little interest in calling out the suspected violation of their online slicer - it's probably just a headless variant of Bambu Studio. But when Bambu started closing their ecosystem and claiming that user agent headers are DRM everyone got justifiably upset, and this is a just outlet for that
It's a shame because the Bambu product line is genuinely first class. They don't need to play these games to compete, and could have won a lot of genuine good will by giving a little back to the community.
> Kühn said; they often rely on mechanisms that an actual judge is not going to care about. In this case, Bambu Studio would pop up a request to download "a little more stuff" with the classic choices of "Yes" or "Ask me later"; users eventually figure out that some functionality in the slicer does not work until they click "Yes". The extras that are downloaded are two .so files built from C++ source. Those shared-library files are dynamically loaded into the slicer—as can plainly be seen from the dlopen() calls in the source code that was released.
This seems to be the main complaint: They ship a separate .so as a plugin.
Saying that an actual judge is not going to care about it is confusing. Is this or is it not consistent with the license? Why wouldn't a judge care about something that is a license violation? I don't get it.
> violating GPLv2 by not providing the source for a Buildroot-based Linux (and other copyleft components) used in the firmware of some 3D-printer models. He downloaded the 300MB firmware image from the Bambu Lab web site, but was unable to find the source or an offer to provide it.
Is there some other technicality that I'm missing?
> Bambu Lab needed a slicer, of course, so it started shipping a modified PrusaSlicer (as Bambu Studio), which it was able to get via the AGPLv3, but without shipping any source code or an offer to provide it. That continued up through 2022 or 2023, Kühn said, until the pressure from the 3D-printing community effectively forced Bambu Lab to make a source release, which was, as is almost always the case for a first release, not the actual corresponding source code.
I googled Bambu's first Kickstarter. It shows July 2022 as the estimated ship date.
So the repo was public and available around the time that the Kickstarter ended. Seems fair? He acts like they were refusing until the community forced them to do it a year later, but the repo was live and open when the printers shipped.
I get that Bambu is supposed to be the enemy and we're not supposed to defend the enemy unless we want a lot of downvotes, but the reporting on this issue seems lacking any fact checking. I didn't try very hard but found contradictory evidence in the first Google link for several of the claims. This is coming from someone speaking from memory to an audience so mistakes are understandable, but I would at minimum expect some cursory fact checking for someone reporting on it
I am gleeful at the idea that courts can't actually enforce open source compliance.
If your response is "Let's force TPP-style international trade courts to force AGPL compliance", well, you're the globalist that Bernie Sanders rightfully warned about and people like trump pretended/lied about being against as justification for why they get elected. I hope you never get what you want. The same crap will be used to patent surgical procedures and other IP in ways that are horrible for society.
You want to do fake software viral communism that's incompatible with how the legal system operates? You're poor as shit and can't hire good lawyers vs business because capitalism isn't favorable to you? That's why you're supposed to engineer something better than crapitalism. This is a grand challenge for the FOSS movement and why I am still broadly supportive of the reasons why someone like RMS votes/voted for the green party (and yes I know they are these days loony/crazy/compromised by the FSB)
Real FOSS is MIT. Learn to make your fake viral communist license have teeth or forever persist in this doomed world you have created.
FWIW the AGPL (which is a nonfree EULA trying to masquerade as a copyright license) has never been tested in court, so the fact that it is nonsensical has yet to actually be adjudicated.
Software and services aren’t the same, and the anticapitalist zealots at the FSF can’t square this circle no matter how hard they try.
Yup. IP abolitionism it turns out is a sword that can slay yourself too. I support abolishing it even to the point of making all EULA unenforceable for good.
It is so much worse than "just" AGPL, YouTube happened to rec this to me yesterday: https://youtu.be/mAm-kpiHRcw. Granted, there are much worse and more pressing evils in our world, but Bambu is just pure and utter evil.

There is no way to stop it beyond getting CBP to block imports, which effectively amounts to shunning.

Or they can pay statutory maximum copyright violations of $120000 per copy violated.
Per copy.
