I have just finished building my power supply. I think my breakout board is bad. I can turn it on But when the computer is on the motors just pulse and move a little. I have to turn the gain all the way down for the fualt light to go off and the motor not to pulse and move. But when the computer is turn off I can turn the gain all the way up. I had ordered the breakout a couple years ago when I first thought of building it, so I don't know who's it is. Before I order another one could someone tell me what they think.
