Thanks for that, the motors are double stack, 76mm long and are (i think) based on nema23's the motion king website states that the current rating is 4.2 amps, i dont know if thats per winding (per phase ?). Can you recommend suitable drivers for these ? I have already started building the table and gantry with bearings made from alli angle and skatebord bearings, i would like to get these motors turning and download some software, just to get thing moving along (no pun intended). lots to think about. Thanks for your help.
