I have checked everything i can think of connection wise, it all checks out ok from the touch plate through the control box and to the computer.

Is there some way of telling on the diagnostic screen of mach 3 if a signal is being received when the puck is pressed.

Mach 3 senses the puck being plugged in and sets the input to pin 15 port 1 in the auto settings but detects nothing from the puck being pressed.

None of the input status leds change when the puck is pressed
