Hm, I will have to try that out, though I am still not sure that this is the issue.
Last night I ran the table with the THC turned off on the program run screen, then switched over to the diagnostics screen while the table was running. I was expecting the Torch up Torch Down LEDs to be lighting up randomly, but they were not. Shouldn't these light up regardless if THC LED on the program run screen is turned on or not?
Is there any reason the Proma would work in the test mode, but would not work when actually running? I am not sure that it is actually sending the up/down signals to my computer. I am going to double check the wiring between the Proma and the plasma machine tonight.
