Hi All, Years since I have been on the forum. I have an RNR motion controller that I'm using on my plasma machine and x,y,and z control is working ok. when running a gcode file the torch on triggers fine but the thc zup and zdown do nothing? I checked on the rnr board connectors and the relevant inputs are triggering ok but giving no z control. How do I assign an action to an input signal? Set thc ports to 3 and signals to 10 11 and 12 in  ports etc config file.

Hi,
I don't think the RnR board supports THC.
