Ohmic sensor and Mach3

[NB Forrest]

On my DIY table I have installed an ohmic sensor and I'm using my floating head switch as a limit switch. It was working wonderfully for several months and one morning I came out to the shop and it wasn't working. When I would touch the torch to the table Mach3 didn't register on the Digitizer light. I ended up putting on a new relay and rewiring it all, new wires and everything. Now Mach3 registers when I touch the torch to the table but doesn't respond and travel to the pierce height. Instead, it continues downward until the limit switch on the floating head triggers. I have active low selected for the probe in Ports and Pins input signals. When it touches ground digitize lights up as it should. Why doesn't Mach3 go to pierce height?

I have a feeling acourtjester may be able to help you on this one, hopefully he is able to chime in or send him a PM

Yes, he is helping me. I am in contact with him. He is actually the one who taught me how to install the ohmic sensor and like I said it was working just fine and now it is not.
