How to setup probe on Mesa 7i96

The input common _must_ be connected or none of the 11 inputs will work properly.

If you ground input common (TB3 pin 12), then apply +5 through +36V
to input 10 (TB3 pin 11) it should:

1. Light the yellow LED next to TB3 pin 11
2. Set hm2_7i96.gpio.010.in true = yellow in halshow
(check with halshow or "Machine Show Hal configuration" in axis)

I think I have it wired that way now. All I know to do now is pull the board back out to be sure it is wired that way. I will probably change pins from #1.

PROBE IS WORKING!!! Moved positive wire to pin 10. Thanks for bailing me out again.
