I think people are making a big nothing burger out of this. Bambu is patching a security issue. Personally I don't want any device or application to send any old G-code to my printer. Like say command the printer to basically destroy itself. Could this lead to completely locking it down in the future? Yes. But they could do that anyways. I think this is a way to stop getting their pants sued off. If they really wante…

Why not implement some kind of open authentication? One that other slicers can implement.

I am angry at the bait-and-switch Bambu is pulling. I bought one of their printers in the Black Friday sale on the understanding it was reasonably hackable and open. Now they're trying to lock it down so I can't print on my own printer without using their approved software and DRM chain. It's outrageous. More info on the hacking (the first in what may be a long stupid fight): https://hackaday.com/2025/01/19/bambu-con…

bait-and-switch? We, those who advocate for open source 3D printers, saw it coming from miles away. This has very very clearly been their plan all along, they themselves said as much (e.g. they are doing the "apple model"). They have been very transparent about this, yet people still fell for it.

As someone who recently bought a bambu printer, I have to agree: I am not surprised. Still disappointed, but in no way surprised. The "apple experience" is why I went for a bambu device (along with the price, and some excellent recommendations from friends). I was even surpised that the "LAN Mode" actually works somewhat good. Should have got a prusa...

I wasn’t really sold on the 4/4S, but I recently upgraded a 3S+ to a 4S and am amazed how much improved. The new touchscreen LCD is a huge improvement over the old two line monochrome LCD. Remote access and wife printing is a nice plus — I don’t even run OctoPi anymore. Automatic bed leveling and no more Live Z tweaking for each sheet has been a major quality of life upgrade and eliminates one of the major pain point…

wife printing sounds nice!

the future is now

I wish Prusa weren't asleep at the wheel, then we would have bought a core one (that is, the hypothetical variant with large build volume and same quality as bambulab). Instead, we bought a P1S, which is, technically speaking, a fantastic machine.

Not really asleep at the wheel. More like they invented the wheel, produced the open source slicer (a fork of the original slicer but vastly improved), which was then used by Bambu who could manufacture a printer for less in China rather than in the EU.

Prusa themselves run 600 printers. They are commercial grade. If I was using a printer for commercial design or prototyping I would go with Prusa. Not only because I would prefer my designs were not sent overseas by an always cloud connected printer.

Come on even makerbot wasn’t that blatant. I believe a lot of us haven’t seen it coming.

I have Bambu, Qidi and Creality printers. Qidi is a good compromise between open and 'print-quality-out-of-the-box'. My Q1 pro is easy to hack, but I have not done anything to it because it prints pretty much as well as Bambu.

Doubt it 2D printers are not open source and you can still print pretty much anything

I don't think you can print cash/paper money.

That is covered by "pretty much anything." That doesn't mean absolutely everything.

Are regular printers that bad, if buy brother? I bought a B/W laser printer and have been generally impressed with the lack of BS that came a long with it. It did ask for toner once, so I bought something from a third-party.

Some are good, some are bad, buyer beware. No direct experience, but I recently read[1] Brother HL-L3220CW counts printed pages, and refuses to print after a set number of pages, even if there's still toner in the cartridge. Some models have a way to reset the page count but this one apparently does not. [1] https://spicausis-lv.translate.goog/2025/01-brother/?_x_tr_s... (I also use a Brother B/W laser printer, got i…

Does the printer also refuse to print when using toners not part of the EcoPro subscription, though? Or is this just another case of people expecting their subscription toners/cartridges to last beyond their payment? I can't blame them, the marketing is sneaky about it, I just see it often on threads about HP.

The post did mention the other toners that came with the printer also locked, but I think I remember reading elsewhere that those printers are cheaper precisely because they come with EcoPro-only toners in the box.

I got my first 3d printer, an MK3S+ a year ago. Pretty late in its lifecycle, but I wanted to spend more time printing than fixing issues.

And it definitely worked! I got the kit and built it within 10h or so (very enjoyable time actually, like building LEGO as a kid) and have printed lots of stuff ever since. During that entire year I only had a clogged extruder one time and had to take that apart a bit. Any other issues I've had were either due to bad filaments or my own errors (not taking long overhangs or low adhesion seriously while slicing).

And all this time I have been using it completely offline with OctoPrint on an RPi.
