Now it does sounds like one stepper is shared between two machines. Does it?? or it just me. One stepper per ballscrew per machine on X axis. I have 2 CNC machines and each one have it's own set of motors and drivers. One is for "wet" another is for "dry" job. I use PM752 from zapp. Motors on X axis are not linked together by any mechanical way apart of Yaxis on my wet machine- 2 steppers, one driver common timing belt. Please see my post no.23
