I am having difficulty setting up my touch plate and would appreciate any sound advice.  I have enabled the probe, port 1, pin 15 active low. The touch test light immediately comes on. When I cancel active low the light goes out.  
My PMDX pin 15 light will light up as it should when I ground the touch plate, however this does not communicate to the Mach software. I have tried different cabling and different inputs with the same results. I have checked the grounds which seem fine.

Does this appear to be a communication error and would (should) a smoothstepper possibly rectify this situation?  Or am I likely to be overlooking a Mach setting?


Thank You

Greg

What PMDX board?

I'd give PMDX a call or email, they should be able to get you straightened out right away.

Gerry;

Thanks, this is an older 122. I will give them a call. Does this sound like a board issue?

By the way I  love your dovetail software, just have not had much time to use it.
