RE: [CAD_CAM_EDM_DRO] Voltage for Full Stack NEMA 23 stepper?

Current Pac Sci motors are rated with a do not exceed voltage assuming
you are using a current limiting drive. So with this motor you can use
up to 65 vdc. If you want to figure out the rated voltage that most
motors would be marked with you need to measure the resistance of a half
coil and use Ohm's law V = 1.75 * R (this is for your motor
specifically, plug in the proper amperage on other motors). My guess is
you will get a voltage in the 2 - 4 v range.

I think you bagged yourself a trophy in this case.
