Hi, I am partway converting an orac lathe to Mach3. However I am having a bit of a problem finding suitable motors for the axis. So far it looks like a nema 34 size motor fits, but the only ones I have found have all been 8 wire, I need 4 wire motor. The original shalf dia is 9.5mm, I can increase the diameter of the motors belt pulley a bit, but think that the nema 14mm shalf maybe pushing it a bit. So what motors have you used to replace the originals ones. Thanks.
