Hi I have Hobbycnc EZ board and i am looking for 3 Nema 23 motors 2/4 phase max amps/phase is 3.00amps and maximum of I believe 4.20 volts. I checked everywhere and it looks like the cheapest is on http://www.kelinginc.net/NEMA23Motor.html and I was also wondering. is 305 oz unipolar the biggest i can go on a Hobbycnc board? I know that the stepper is rated at 425 oz but that is bi-polar and I guess that is all that Hobbycnc board can do. Any suggestions? Would it not be worth buying steppers for my crappy board instead, buy new drives such as kelinginc. kl-4030?
