G32 Error: Bed calibration :

979044817

Hello everyone, recently I'm doing 3Z, automatic leveling, but I don't know how to solve the problem, please give me some advice

Because I don't know much English, so I use the translation software. If there are some wrong words inside, please forgive me. Thank you!

It will not be automatically leveled after 3 coordinates are detected

Have you see the examples and instructions here?

Why do you start at P2 P3 P4. Should be P0 P1 P2

@phaedrux
Thank you for your advice! After modification, the altitude can be compensated, but the direction of compensation is reversed. The compensation of P0 should be downward but upward

@phaedrux What should be changed?

Phaedrux

The order of the points probed must match the order of the motors making the adjustment.

Note: If you are experiencing the Z axis compensating in the opposite direction needed, that means your Z motors are swapped. You can either swap the X values in the M671 command, or swap the stepper motors plugged into the Duet.

@phaedrux Thank you for your help. 3Z auto leveling is working now
