Finally got my Proma THC working and looking for some help dialing in the settings. I have a Thermal Dynamics Cutmaster 38 plasma cutter, cutting 12 ga hot rolled steel. It seems to cut best right around 90v on the THC display but it seems to be constantly adjusting up and down so that the cuts are kind of wavy. Do I need to adjust the voltage range of the THC, the voltage output of the cutter or what? Using Mach3 software with the THC plugin and cut height of 0.060.
Thanks!

Re: Proma THC settings
Try adjusting the THC speed on the Mach3 screen, slow it right down so height adjustments are barely noticeable and then play with the `up & down` voltage buttons on the Proma on the fly, while cutting, for best height. Proma works well for general cutting but would struggle over corrugated sheets, too jerky at speed but great for entry level THC, works great for me on 3 different plasma cutters connected over time, with very little adjustment to suit each.
Hope this helps

Re: Proma THC settings
I have the HYS set at 2. I can't change the THC settings in MACH3, it keeps reverting back to the default.

Re: Proma THC settings
The above example states it should be higher, do some test cuts and increase the setting to what happens.
