Hi guys.
Please help. I have latest Mach version, license, touch sensor, which give me 2 signals Up and Down.
I didn't connect computer to breakout board yet, and try to turn Mach, by keyboard emulation.
I had assigned UP signal to "U" button and for "Down" signal - key "D" (Ports & pins -> Input sig) of course THCon too(key "O").
Ok. Questions:
1. Why Mach doesn't do anything when I press "U" or "D" key, but in the Diagnostic screen LEDs are works. But Z axis doesn't move.
2. I've make brain for those buttons, and it work, but it doesn't move when G-code executed. When I push the "O" key, brain don't work too. When i push-Up "O" key, brain allow move Z axis.

Please Help, who know why THCUp/Down don't move Z axis. What I do wrong?

And one more. Up/Down("U" & "D" keys) and "Probe"("P") key don't do anything when brain is off. So without any tricks THC do nothing.
