I’ve been running some tests using UGS to air-carve some of my Easel projects that I exported as gcode. One of them, the simplest one, is actually causing some weird behavior. The job starts out fine in UGS and proceeds line by line until reaching the end. At that point though, the machine just keeps repeating the same passes it just completed - over and over.

Has anyone else seen something like this? My gcode is below:
