Hi
is this the same issue but posted in Deutsch?
I am having similar issues. No activity from the Z axis for the bed height, no movement or activation. All wires look correct, no visible damage. LED says z-switch error, however z-switch is clear and 'clicks'.
This has happened while i have been trying to fix a short on the heating wires, but have no idea why the bed z movement has now failed!!!
Additionally, main board is super hot to touch?
How do i check to see if the motor is getting power?
