Motor Drive / X stepper only works manually

Issue Description:
We can only change the Z height of the engraver head by using the manual lever. When we attach the motor module and use the “Up” “Down” control switches on the cabinet, the galvo head is unresponsive. We checked all the cables and connecting parts, and they are connected properly. Not sure what is wrong, please advise.
