I am using Mach2 and I am installing Bob Campbell"s THC300 box. I built a floating head for my torch head and mounted a switch on it for a probe. I have it hooked up to sensor board, probe lugs. I have Digitize bock checked, port 2 pin 13 on Input Pins screen. Digitize LED is lit up on Diagnostics page. When I trip the switch by hand, the LED doesn't change, is there a way to check to see if Mach2 is picking it up?
I was also checking the fine and coarse adjustment knobs on THC box. I had the jumper across TP5 and TP8 like user guide said. Turned coarse knob CW and the UP LED lit up on Diagnostics screen and THC box. Turned it CCW and the Down LEDs lit up. The user guide said it should of worked the other way. Does any one have any ideas?
Thanks
Chuck
