Hi there Boyan.
I just want to know if the PMDX controller is good for mycnc6040 with standard motors and or the Nema 23 Bipolar (Holding Torque 3Nm) (425oz.in) 4.2A 57x57x114mm 4 Wires better for it with the PMDX to move fast and do I need a switching psu of 36v~40vdc for the Nema 23 or can I use the same 24v dc that is in the blackbox already?
