I have gecko g540 and Mach4.

I have a home/limit switch at the top of my Z. When I ref all, the axis goes up to switch, then backs off, works correctly.
I just bought a Z probe off of Amazon

Here is my question, can I connect the wires from the probe to the wires on my Z limit switch? Then can I activate the same pin in Mach4 for the probe function? It’s no different than having 2 limit switches on the same axis.

The reason I need to do this is because I have a burned out input on my g540. The other 3 inputs in use are limit/home for X,Y,Z. I do not have a BoB( don’t want to get one unless I absolutely have to.)

Hope that makes sense

If the limit switch and probe are both normally open, I would think that connecting the leads in a "Y" configuration would allow the current to flow when either were triggered.
