I know this might seem like a wild goose chase…
OK so you did NOT see the torch fire, correct?
I think that is good, and given the error message I think it could be your pierce delay. You have it set to 0.5 seconds. The CrossfirePro has an inherent delay of about 0.3 to 0.5 seconds (relay closing) that needs to be added to the machine published pierce delay. For example the published delay for my Hypertherm for 1.5mm steel is 0.4 seconds (40 amps fine cut). So the total pierce delay required is:
Torch Delay + CrossfirePro Delay
Go back to Sheetcam and increase your pierce delay to 1 second and try your file again. If you are good with computer software, use a screen recorder
to record the screen. Use your phone to record the table/torch.
If that fails you could go back to 20.5
