okay I have a problem...going through the brains on the torch up and down comand the Z axis is very jumpy.
also have up and down Leds on screen set with THC enable button & led and none seem to do anything...have not tried it with g code just on test bed...Maybe Scott AKA poppabear can help with this? if he has time...
If I use the shuttle All axis are smooth and liner....it is only when the brain turns on the torch up or down...
Thanks for any help
Dave

hi, on the mach plasma main screen , under the thc on button, there is a setting to control how fast mach moves the z axis. i have mine set to 5.
