Hello
I have a Denford Minimill (aka Sherline in the US). I have fried the main control board (long story) and despite replacing lots of the components I'm still not making any progress in getting the thing moving again.
Since the mechanics, motors and power supply are all in good order, I'm wondering about the feasibility of replacing the electronics with new driver boards. But I am not sure what I need. The steppers are sanyo denki 103h7123-0440. They have 6 wires and I think they are unipolar rated at 2A. Does this sound ordinary enough that I can use cheap generic driverse, and if so - any recommendations?
