Hello, looking for help in a way to hook up a Z touch pad, however my machine has no limit switches.

The board has no provisions for limits or other plugs, many empty holes to soldier wires to the board.

I did find a program that works with Mach3 for setting everything up and finding the proper pin once hooked up, but recommends pin 15....I tried ringing it out with my meter, but find nothing without power that has continuity.

Any help appreciated
