X1Plus: Custom Firmware for Bambu Lab X1 and X1 Carbon 3D Printers

Saw this mentioned on the big thread about Bambu Labs recent “security” update. The project hadn’t been submitted in several months, so I figured time to resubmit.

Since the project was started, TeachingTech put the X1Plus devs in touch with Bambu Labs corporate. Apparently as a result, Bambu released tool that allows you to downgrade your firmware to a version X1Plus can exploit to sideload community firmware.

Here’s how it works:

As far as I can tell, this is exclusively for the X1C. There is not yet an equivalent for the P1S, correct?

Correct - the P1S and other machines do not run a full Linux AFAIK.

One third-party manufacturer is looking at making replacement control boards.

Does this still allow use of the lidar + laser leveling systems?

Yes it does.

The bed levelling/tramming process is even better and gives you more information/control over things.

So far, I have had it for a week, printed about 36+ hours and not a problem - seems smoother than before.
