No Arc Detected

I am just testing out PlasmaC and I am using a Hypertherm 65 and a MESA 7i96 and a MESA THCAD 5 to control my plasma cutter. My settings are in this image
I tried to do a Single cut and when I pressed Start Cut it probed down went up to the price hight and struck the arc and held it for a few seconds then waited and tried again. This happened three times and it gave me this errorWhen the arc was on I looked at my Arc Voltage and it said it was at 173V. The Arc OK single was not on. I have configured PlasmaC in mode 0 so all of the THC stuff is done by the MESA THCAD 5. Some help would be greatly appreciated.

Is the ArcOK signal from the Hypertherm wired to the 7I96?

I really think you are setting up for failure if you choose to use a synthesised acrOK signal when your machine has a real ArcOK signal. Sooner or later there will be a conflict becasue you think you have good arc and the machine knows it hasn't.

I am know using the arc ok single from my plasma cutter and no longer have the problem.Thanks guys!
