Nan - voltage

It seems to me thats what should happen, but that did not seem to be the case.

I don't actually know what happened afterwards, all I knew about was the wrong display value. Maybe Tesremos will fill us in.

So was it just the display value or was the arc voltage used by plasmac wrong too? You would not have thought you'd start cutting 1 second after turning the machine on.

Both the display and all the plasmac comp calculations.


I just tried on a sim and everything seems to come back to normal afterwards. It gave this vague error dialog:

Looks like Dewey has pushed a fix to halshow.tcl 6 hours ago so it would be interesting to recompile master and try again
"halshow.tcl support display of nan"

Sorry, just to be clear, WatchLoop in in that file.

it crashes into stuff.
