    How do the connections on limit switches labeled C NO NC match up with the 3 pin connectors on the Black Box (GR L D)?

    I am trying to add 3 additional 2 wire limit switches that I have to the 3 wire connections that are hooked to the Black Box. So can I hook the C to the GND and the NO to the SIG for a normally open setting? Is the 3 wire connection configuration at the Black Box a normally open configuration for the new GND - V+ - SIG limit switches ?

    Ignore the V+ pin. The link I sent you says "TIP: To use Normally-Open switch wiring, ensure that $5=1 in your Grbl settings". In other words, the BB will work with either NO or NC wiring. You just need to make sure you set $5 in grbl correctly.
