Does this mean that we cannot use a N/C end stop wires in to the end stop pins? If so what do we have to change in the software. I have purchased one of these boards and have flashed the regular cnc software in it . When hooking up the stops They show as hooked up by way of the led next to the motor connector. But when they are activated there is no effect on running the motor from the control panel. (Great control panel by the way).
