Another way and maybe more fail safe would be to put a temperature switch on the machine and then look for a trip before you do the next cut or pierce. You can use the Gcode digital input (M66) for this if you are on Linuxcnc. With Mach I dont know if you can read a pin from Gcode.
You could also hijack the "ArcOK" signal through a thermal switch

Thanks Marius,
I'll look into them, but the number of pierces is not really the issue. For example, I could have cut 10 open lines that were only 40mm long. That won't cause the issues described.
On the other hand I could have just 2 cuts but each one is quite long, and the compressor may need to catch up, or the plasma cutter need to cool down after just the first cut. It's the cut distance that's important.
Do these posts also do that.
It would be a great feature to have in an operation. Two entry boxes where you can set cut distance and pause time.
