Hey Everyone! I picked up one of the sainsmart 3 axis boards to replace a very old hobby cnc board. I tried searching on this but i didnt come up with anything. I have everything hooked up right, the axis lights work as they should showing the board is getting a signal from Mach3. However my motors do nada! The steppers im using right now are some 70oz steppers that i got with my hobbycnc board. They are unipolar, but my understanding is i can use them as bipolar motors by not using the center tap on the coils.... just using A+ A- and B+ B-.. The board powers up fine and lights as Mach3 sends the step/dir feed but the motors will not turn... anyone else have this issue?
This is the exact board...
