I seem to be able to probe ok with mach4, but having problems with mach3 the probe led signal is always flashing haven't been able to get it to work correct if I set it to signal high the led is always on and of course mach3 thinks the probe is triggered active low and the led flashes constant in mach4 I have it set to active high and works fine not triggered but seem to work the opposite in mach3, I do see that emulated is checked in mach3 but I can't turn it off to see if that helps it always turns right back on..

Any suggestions
sorry if this is a repost but the search function doesn't seem to be working anymore..

Thanks gary
