[Mini Miller]

Hey guys, I have done so much research that my head is spinning. I have purchased a set of Superior Electric Slo-Syn series M092-FD08 steppers for my Grizzly mini-mill cnc project. The motors are rated at 3 volts, 4 amps and I will be using a 48 volt, 10 amp power supply.

I am looking for a low cost stepper drive that can take 50 volts or more and handle 4 amps per phase. I have looked at most of the drive makers that we know of and a lot of them only handle 2.5 or 3 amps, or the voltage is not high enough. Is my only choice to go with Gecko 201 drives?

From what I have read here, the recommendation is to go with a half-winding wiring scheme for fast stepping and higher power output. Is it not a good idea to go with a full-winding scheme and get a lower power drive? How about some of the unipolar drives with less features? They seem to have the right current handling capacity.

Thanks for any help that you can offer.
