STEP 4: Test the Wiring and Configuration: 

  • Press the knob three times to enter test mode in the THC and observe the ARC OK signal activate.
  • Turn the knob up or down to move the axis and observe the Torch UP and Torch Down LEDs activate when moving in each direction.  The Z-Axis should also move to adjust the position.
  • To exit test mode, press the knob once.



  • If the height adjustment is not smooth or overshoots the position, lower the % of correction speed.

  • Make sure MACH3 is properly licensed, and THC does not work on DEMO Mode.
  • If you do not see action on the signals coming from the THC, try tracing them by measuring them at the output of the THC, the input of the breakout board, the LEDs of the breakout board, the Software Diagnostics, the software function, etc...  You need to understand where you are losing them.
