Y axis on usb controller not working. The motor gets power and holds but will not turn. I tried switching the same wires, driver, and motor over to the A axis on the controller and it works fine like

This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.
