Craig, thanks for the reply. It is something I've been considering, but wasn't to happy with the idea.
This is an issue I've been pondering for several months. After posting the question, I realized I was worried about voltage loss with a 5VDC input, but the drives will support a much higher voltage through the opto isolators, so adding a 12vdc supply will resolve any voltage drop. Now I'm considering using the higher voltage to hold a relay transferred and with a drop use the NO points to hold a + signal to Mach3 E-stop inactive and a drop to trigger it
I don't like the idea of some dozen or more inputs, when one will do. I think I caught this one soon enough that I don't need a Revision 3 of my BOB wiring, Hope so anyway.
Don
