Okay,so Z axis is not working. I tried swapping Y axis cable with Z axis on the stepper motor, the motor moves down but doesn't go up!Next I swapped, the X axis(not Y axis because it was little hard to unplug and X was easy to unplug) with Z axis on control board and in this scenario too the X axis moves and Z doesn't! Voltages seems to be okay aroung 0.56, so I can assume that I have a faulty control board?
