I am struggeling during upgrading my Ultimaker-Clone with the below mentioned setup:
Setup: BigTreetech SKR2 RevB, TMC2209 steppers, TFT35 V3.0.1, X and Y: mechanical endstops, Z: hall-endstop.
The Z axis is driven by a belt drive.
After wiring and setting up the firmware for NOT using sensorless homing, the following problems appaers:
By homing the Z axis, the bed moves up correctly, but after triggering the hall endstop, the bed falls down about 120mm and then goes upwards again towards the endstop. This would be done continiously if I would let him go…
Any idea where I missed something? The config files are attached. Thanks a lot!
