I did my searches and reading and need to get confirmation from somebody smarter than me that I am on the right track.
It's for a Taig Mill/G540 system. I am going to wire the limit switches in series and connect one end to Pin #1 and the other end to Pin #12 being the GRND. This will be a normally closed (NC) system. I am going to use the same limit switches at the home positions for all 3 axis and they will be connected to Pins # 2, 3 and 4 and Pin #12 GRND. This will be an normally open (NO) system.
Then I will configure Mach3 accordingly with active lows for the NC and active highs for the NO system.
I've being looking and looking for schematics to confirm my wiring but haven't found anything useful. Have I got things setup properly so far?
