Bed leveling not working (TMC2130/PINDA sensor)
March 13, 2022 02:40PM
Hi Internet!

I had to change my Bear-PrusaMK3s´s mainboard and decided to go with a "BTT002"-32bit drop-in replacement board for the original Prusa Einsy Rambo board. I prefer Marlin anyway ;-)
Ok, so I took the MK3s- default config from the marlin configs and made it work with the new mainboard. There were some TMC2209-specific entrys which I changed to TMC2130-values like the endstop stall sensitivity, as well as SPI-Endstop settings.

But, my Bed leveling does not work, neither bilinear nor UBL.

When I do a G28, everything works fine, the head moves to the left and touches the frame, the bed moves to the back and touches the frame, then the head moves to the center of the bed and lowers until the LED on my Pinda probe goes off, so clearly everything related to G28 seems to work.
When doing a G29, however, the bed and head heat up (I configured it that way), the head touches the left frame, then the bed again the back, and then all of a sudden the leveling stops. Both with Bilinear and UBL.

I have made a detailled bed level log (M111 S32) and included it. It showas what I have decribed above, so, G28,G29. I also have included my config.h and config_adv.h.

It would be awesome If anybody has an idea whats wrong here.

I don't think that the leveling commands are the problem. Both UBL and BILINEAR worked properly on my printer. For BILINEAR I used the commands in your log.

I think the problem may be that Z_PROBE_LOW_POINT may be set too conservative (one of the settings in configuration.h). Your log says Error Probing Failed which means it failed to get a signal from the probe before reaching the Z_PROBE_LOW_POINT position.
