Needless to say it was working before.
When I connect the probe wiring to the work piece or the bit in the spindle using an alligator clip I now get a random blink as if the probe has touched the work piece. (Used to stay on during testing until I disconnected it)
I've not made any changes to the system.
I've checked the wiring with a multimeter for continuity from the wiring right up to the Gecko 540's pin 11.
I tried adding a 1k resistor, a 68k resistor, 150 ohm and 220 ohm resistors to no avail.
I even tried to emulate and still got no response in Mach.
I'm wondering if the Gecko's gone bad. Everything else seems to be okay.
I do have another parallel port with a BOB and may trying different Ports & Pins for it tomorrow just to see.
I've loaded other screensets and that didn't work either.
Like I said, I've changed no wiring or settings, just tested it before probing down (as I always do) and discovered that today it didn't want to play ball.
Any insight for other items to check would be appreciated.
