@phaedrux said in Z Motors not moving:
I believe you're missing an M584 command to specify how your z axis motors are bound.

According to the doc "Any M584 commands used to remap drivers must come before M350 and M906 commands." M584 is only used to override defaults. I believe as long as X is 0 Y is 1 and Z is 2 you don't need to specify.
