I have an intermittent issue where my torch is continuing to fire as it jogs between cuts. It doesn’t do it in the same spot every time, so I don’t think that it is a gcode error. The z axis raises and it jogs like it is supposed to, but the torch is cutting the entire time. It’s not cutting through metal during the jogs, but it is leaving some unsightly marks, and the following piercing isn’t clean.
Make sure you are in 2T and you have the torch height set high enough so the arc goes out before moving.
