K8800 vertex delta 3d printer stuck on home position

K8800 printer looks to be stuck on the auto-home position. After it homes it doesn’t move no matter what I do. Any ideas?

See attached video.

Bump. I’m desperate here. Nobody knows what to do? :cry:

It won’t calibrate on the XYZ-Axis and level the bed or move the printhead while it’s printing.
It doesn’t move from its position after auto-homing during those actions.
