I have an error that popped up suddenly on my Y axis. I've unplugged all limit switches. I've unplugged everything, checked all connections and done everything i can think of with no luck. While unplugged, I've rebooted the box and the light goes off. I plugged it in and the lights comes back on. I then tried same procedure with the Z & X into the Y axis, same results. So.......is it the box? Because no matter what i plug in it, the light comes on, but only on the Y. I've switched all wires back and forth with same results.........HELP!!!!!
