I wonder, my THC and all other commonly used one with Mach, I would imagine just send a signal out for Up or Down. So if I were to have a Z axis on the plasma but in addition have a small servo on the torch that could raise or lower the torch via a second small slide, I could possibly control that servos drive via my THC Up/Down signals.
In the screenshot below you can see I can configure the drive to presets, basically what that means is when a signal is seen it will do the RPM configured.
As you can see I have just entered a number of 1000rpm for Preset 1 and -1000rpm for preset 2, (Preset 0 is the default when no inputs are active, thus it is set to 0rpm) Accel and Decel can also be set there.
Will try and test this theory out in the next while but before I waste my time does anyone see anything wrong with my thoughts?
