General Mach Discussion / Re: Probe wiring

If you have Probe configured active low and configured to pin 10 and enabled then connecting pin 10 to GND (pins 18 - 20 of the parallel port) will light the Digitize LED.
Perhaps you are not connecting pin 10 to GND (the machine spindle or machine frame may not be GND).
Perhaps what is labeled pin 10 on your BoB is not actually pin 10 (check continuity of wiring).
Perhaps pin 10 on your parallel port has died (try another input pin#).
Tweakie.
