Relevel the bed?

I assume this is with a Ender 3 pro (as per your signature) with a single Z axis?

Ok thank you.

post your config and homing files for verification please.

Or flip the connector on the board.

Unfortunately no such damage is not covered by warranty, since it's akin to a wiring fault.
However, we may be able to offer a refurbished unit on exchange at reduced cost. Please contact roland@duet3d.com to inquire about availability. Include a link to this thread.

Thanks a lot for the support, troubleshooting/preventive hints and the suggestion with a refurbished unit!
And thanks a lot for your guy’s effort and contribution to this community of additivist enthusiasts!
