      I'm installing a latching e-stop on my machine, and I've plugged it into the two reset pins, but it turns out the operation is inverted - the contacts of the switch are NC, but the board needs NO... Is there a configurable way to invert the board, so it accepts NC?

      Cheers

        You can invert the pin by prefixing the pin name in M950 with an !.

          What's the pin name for the reset pins? I can't see it listed here:

          Any suggestions?

            Doesn't have one, its a hardware reset pin directly to the microcontroller.
