Thanks for the reply. As you can see, I am pretty much desperate to get some sort of answer to my plight.

So basically, it is like milling a part rather than an actual plasma burn? I run mostly 16 ga, sheet stock for my projects, up to 3/16", so THC is pretty much essential. I am looking into Proma THC, and also capacitive sensing THC, but no decisions made as of yet.. Neutron never answered back both of my tech emails, so they are out.

Oh-btw, what is OHMIC?

I wonder if I can ask you where the plasma trigger is located in the G code you posted? How did you accomplish this with the Acorn board? My machine is a Thermal Dynamics Cutmaster 101, and I have a built in trigger that the previous system used for firing the torch. Is this sequence done through Sheetcam? Please let me know. And thanks again for your help.

I use M3 to turn on the relay for the plasma and M5 to turn it off.

I don't use sheetcam but M3/M5 should be the default for the plasma torch on/off.

So if you are not using SheetCam, are you plotting your parts with a cad system, saving the DXF, then manually entering your M3/5 points? Sorry to be redundant, just trying to get a better idea as to how you are going about things. I mostly trace bit maps of JPEG images, and will use SheetCam to generate my tool paths, sort of speak. Thanks again for your help.

I am using Fusion360 to generate the gcode. I wrote a post specific to my setup.
