TP-
I was able to play with the table some tonight, and I am not having any luck.
Here is what I know.
1. Everything is working on the table except the probe to determine TOM.
2. when I watch the diagnostic page on Mach for CandCNC boards, I can watch the bottom row row of LEDS and one of the middle ones turns on and off when I manually toggle the switch.
3. I wrote a simple program just like you have suggested. Turned the speed way down, and as the z is moving down looking for the TOM, I manually toggle the probe switch. Nothing happens.
4. I have also tried changing the ports and pins for the probe for both HI and LOW.
5. I have also tried enabling the toggle switch for THC. The indicator for THC flashes a green LED. If I remember correctly, I thought this stayed either on or off. Not flashing?
There has to be something in Mach that tells it to either use the HOME SWITCH or the PROBE for the G31. A macro or something
Any other ideas??
I promise this did work last year!!!:)
Thanks
