Flashforge's recent threats to the 3D2A community have revived the discussion around privacy in printing. How do we ensure that our printers aren't spying on us, blocking us from printing and tattling on us to the feds?

I made a video reviewing three techniques you can use to protect your privacy and keep yourself safe when using Bambu printers. These techniques can extend conceptually to other printers too.

Good info for those who already have Bambu printers. For those that don't, it's worth mentioning that the best solution to avoiding privacy issues with Bambu is avoiding Bambu. Bambu has made it abundantly clear that they do not accept or support your right to decide how to use the printer that you paid for. This isn't about them being Anti-2A, it's about them being anti-user-freedom.

Bambu isn't the only game in town. QIDI, Elegoo, and others make good printers that actually respect your freedom and privacy, integrate seamlessly with Orca Slicer, and won't force you to sneakernet your g-code on fragile SD cards. You can set up your router to block all internet traffic to/from these printers and they'll continue to work perfectly - no mysterious "LAN mode" needed.

Yes, the Bambu printers are marginally easier for the chronically lazy to get decent prints out of. But we've come a long way from the days when the alternative was spending hour-after-hour trying to beat an Ender into submission. And yes, in some cases they will produce prints that are aesthetically better (though the difference is becoming more and more marginal). So if your primary goal is getting likes on Instagram, by all means continue to support the erosion of your right to own your devices. But for me, freedom is a big part of what we do here. If you value that, consider supporting the companies that respect that and avoiding those that don't.

As an X1C user, I agree wholeheartedly. I'd also advise those of us who have X1s to run the x1plus custom firmware, as it enables more freedom to manipulate your printer and lets you actually have faith in LAN Mode.

Lil annoyed there’s no cfw for P1s/p1p yet, seems like the platform is perfect for it

It has to do with the compute. They may speak the same protocols to Bambu network services and have similar underlying drivers, but the X1 has a full fucking ARM Linux board in that head unit where the P1S runs a random microcontroller. x1plus is a custom Linux distro with an ARM bootloader, not too dissimilar to a RasPi.

I didn’t know that the x1c was powered by a sbc, nvm I fully understand it now
