There no wires to the pierce terminal only Torch, OK to move and Start. When the controller is on there is a green and amber light on. is the amber light the input status indicator? Just to clarify we have the blue AVHC box and the compact (one piece) controller. I jump torch and it starts pulsing looking for ground. Jumping start with my Fluke ohm meter mimics the same actions as clicking start in the computer program, drops down starts arc, the OK to move switch closes and then it just sits there with arc burning and times out. When I jog the X axis 1st and third light on the controller lights and moving on the Y axis lights the second lamp. and when I hit start in the program all three light up until the cutter is in place drops lights and and times out. I have jumped the controller's OK to move terminals with no results and have held the OHM meter leads on the start terminals and still didn't move. Is it possible it could be a computer or software problem? When the controller is on there is a green and amber light on. is the amber light the input status indicator?
