cnc limit and home switches

meant different pins at the end of the vid not "ports", and my breakout board is at the maximum ammount of inputs right now so I cant put any home switches on the meachine until I figure out what I can either combine or remove to make more space for more switches. Or get something to expand my number of inputs

Also did you have a good explanation how to set a probe?

[jamesmorgan]

You can use the same switch for a limit and home switch with a properly configured Mach 3

What different ports are you talking about? There is only ONE port, which is port 1.
