Hi.
I have a problem. I took 2 piece OEM750 (used) on ebay. First OEM750 perfect working not a problem. But second OEM750 not working. I used same setting and same stepper motor both driver. Stepper motor not turn. At the same time stepper motor shaft be locked i give energy on the OEM750 (for not working OEM750) and green led (POWER) on red led (FAULT) off. What problems?
I am using Mach3.
Thanks
