General Mach Discussion / Issue with THC in Mach3
« on: February 09, 2012, 01:25:14 PM »
The position of my torch proximity switch determines whether the THC-Up or THC-Down signal is high.  In testing my system, I have a switch to signal THC-On and cutting starts after meeting the conditions: a) reach M3 in my code and b) THC-On switch turned on.

I am still unable to to use the the THC-Up and THC-Down signals to control the Z-axis.  What is the protocol for using the THC-Up and THC-Down signals? I initially set the Z-axis value to a number somewhere between THC max and THC min.  After turning on the Torch-On switch and cutting starts, and after I place metal near
the proximity switch, the THC-Up and THC-down signals switch state but there is no output from Mach3 to my z-axis. The THC button is green.

Thanks for any assistance in figuring out what I am missing here.
