Question #: 15621

Question: Mach 3 USB motion card: what two pins do I use for the limit switches and E stop button? One of the wires pulled lose and I don't remember what the other contact was.

Current Solution

You can use any of the inputs on the mach3 controller. If there is a free terminal input terminal, use that one. You will need to modify the input number in the inputs tab in config->Ports&pins to assign the limit to the correct input number. When adding the pin number, make sure that the port number is 3.
