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?

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.

Hello sdirkx,

Check the pulleys on motors X Y Z (if they are fixed well with setscrew: sometimes it’s loose).

Then Reset the main board:

Push on rotary knob to open the menu:
Go to SETTINGS
Restore failsafe
Initialize EEPROM
Store Settings
go to Vertex Calibration
Auto Home
Calibrate Height
Auto Calibration
after message “Calibration OK” => Store Settings.

Hope this will help.

Best regards,
