Help, I have 2 closed loop vexta stepper motors on a machine I have just bought. The machine has no drivers, I am looking for a 3 axis driver system, now can these closed loop steppers be run by a Bipolar or unipolar driver? or does it have to be a closed loop controller? I am not that bothered about the feedback system working as with the closed loop system, I just want to run the machine.
