The open path at the bottom is there to cut the sign free from the larger stock piece that I use. I corrected the ‘Y’, but that wasn’t a problem in the previous version and didn’t correct the problem with the current version. I’ve cut this file with the previous version with no prolblems.
I managed to simplify it down to see the root problem, it’s not the self intersection, it’s a problem in the code. It’ll probably take a day or two to get this one fixed.
V 740 seems to have corrected the issue. By the way, cut times have been reduced on several projects that I checked in the neighborhood of 15-20% (15 minutes for this project). Toolpath calculation is almost instantaneous instead of waiting for the pocket calculation.
Good work!!
