I have setup my formbot voron 2.4 R2 pro+ with m8p + cb1 and sb2209 can. I have added my .config files. When running klipper, all motor test works (STEPPER_BUZZ STEPPER=stepper_x), heater and temerature works, lights and leds works, endstops work as intented, inlcuding tap (QUERY_ENDSTOPS). When homing X or Y, the front 2 Z Moters (Motor Z0 (Motor 3A) and Motor Z3 (Motor 6)) move up and the back Z motors do not move, making the gantry racked. Then the Y homing continues as expected. Is there something wrong with my klipper config files, or would this be a fysical problem (Belt tensioning, etc.). FYI: I have the formbot 300x300 kit and I have turned the Z0 (Front left Z motor 90 degrees as mention by this guide).

This might be a direction problem? My motors are coreclty wires as in the comments of my .cfg files, i have tested this with motor buzz test

Are you sure you did the full buzz tests, as shown in the startup guide?

#

(Which explicitly calls out which direction each motor should buzz. Not just that it buzzes)

No, it was a direction problem. It is fixed now, hopfully my voron gantry has not taking to much dmg from being racked by this
