Hello,
i am experiencing a problem with my K8400. The extruder motor stutters and cant load the filament. Its moving back and forth very fast and i have no idea why. I hope somebody can help me.

Make sure the pulley on it is at the correct measurement.
Check the driver make sure it is in the correct orientation.
Try swapping it between the X or Y driver to see if the problem moves with the driver.
If all of Wrong Way’s options are OK check the driver reference voltage (should be about 0.9V).
