Re: [CAD_CAM_EDM_DRO] Choosing Power/Volts on Stepper Motor

Robert,

I am referring to the amount of volts the driver can handle.
If I can get away with 30 volts max. on a driver and still get
the needed IPM out of the motors, then the driver does not need
to be rated so high. Certainly Geckodrives are the ones to use, but I
am trying to minimize cost on the first CNC I make.

So I am trying to decide if this driver will serve my purpose since it
is 4 axes and only $129.00.
