Auto Flow Dynamics and Rate Calibration No Longer WOrking

I recently had to change my TH board and Lidar. Accidentally pulled out one of the small connectors when swapping the hotend. I had an older TH board, so I had to get the dual laser Lidar as well. Installation went fine, no errors. Ran a few prints without issues. Went to calibrate some new filaments and received a “Part of the calibration failed! You may clean the plate and retry. The failed test result will be dropped.” message. I checked the printer and the screen had a message saying calibration was successful. However, there was nothing printed. Tried it again, but the actual print isn’t even running. Restarted and ran device test and printer calibration. Got it to work once after that before it returned to the same issue. Any ideas?

Are you able to print other things such as the benchy included with the printer?

I haven’t tried what’s stored on the printer, but everything has been printing fine. It’s just been the auto calibrations. I’ll give the built in bench a try when I get home.

Its a firmware error…We need to wait for a fix.

The manual is working, you can try !

Oh really, has that been confirmed? I got to work randomly once or twice over the weekend, then it stopped again.

yes, confirmed !

Another user got an response from Bambu.

Mine works for an entire day, after an restart, stops again

Awesome! Good to know I didn’t screw something up with the Lidar install. Thanks for letting me know!

When will this get fixed? My Lidar is failing every calibration.
