Hmm....out of the box also for what it's worth,
- code - maybe try coding using arcs but an code arc / cicle for 4 quadrants
this comes to mind
It is not good practice to program radius format arcs that are nearly full circles or are semicircles (or nearly semicircles) because a small change in the location of the end point will produce a much larger change in the location of the center of the circle (and, hence, the middle of the arc). The magnification effect is large enough that rounding error in a number can produce out-of-tolerance cuts.
Nearly full circles are outrageously bad, semicircles (and nearly so) are only very bad. Other size arcs (in the range tiny to 165 degrees or 195 to 345 degrees) are OK.
- Not much knowledge of plasma, but when my friend uses his welder "sometimes and not repeatable" it realy can do a number on the running machine, in fact has corrupted his pc or needed to reboot as Mach did goofy things.
This is an RF problem / noise and has to do with existance of a field of right intensity hanging around ( non-technical explaination
).
FWIW,
