One more question....coming out of my cnc port on my plasma one of the pins is called a ground its for the work piece lead but its actually positive polarity. Where would i hook this up on my THCAD 10 board? Or does it hook up somewhere on my 7i96 board? Dont want to smoke something this close to having it fully work.

Nowhere.

Can you post a scan or pic of the page from your manual link to the manual?

Tommy's right. Its not needed at all. Instead I would use shielded cable connected to one of the centre pins on the THCAD but leave that unconnected at the plasma cutter end.

That will get to 300V positive refferenced to ground or earth, so not healthy at all for the electronics.
On plasma cutter with no divider that will be the + to the THC.
Yours has a divider so that is not used.
