I'm in the planning stages of a repstrap. I've been checking the surplus sources available to me and I note a glut of cheap steppers with only one issue, the stock voltage is either 24 or 36 volts.
I was looking at the controller boards, and I was thinking I could lift a trace that's used to feed the steppers 12 volts and then just bolt a 24 volt power supply right next to the ATX, I could make use of these motors. The driver chip seems to be able to handle 36 volts. I know I'd have to make sure the current stayed below 2 amps
Aside from the fact that I'll need to source a second power supply, does anyone see any issues with taking this route?
