Hello,
I'm using a plasma CNC since 2-3 years and would like to add it a THC. Connection seems fine but have a problems with mach3 that I can not understand.
First I'm using the "test mode" of my THC. (command up and down for 1sec each to move the spindle)
During the test I can see on the THC the commands UP/DOWN.
I receive the signal in MACH3 but my spindle does not move.

Anyone has already face this problem? and solved it

There is also some of my configurations:
Plasma : hypertherm powermax 85
THC : compact THC controller from PROMA elektronika
Motor command : Box CNC-shop with board TB6560
A SmoothStepper to convert USB to parallel port
