I have a series of circles that are to get an inside offset cut (automatically from an outside offset operation). When I add the overcut, a circle or two (not all) only have the lead-in, overcut length and lead-out, but no main cut. If I remove the overcut, the circle’s cut path shows up. See screenshot.
I am running Ubuntu 12.04, SheetCam TNG Development 5.1.12 under Wine. Any ideas?
