Those arrows are all over the place for me. Sometimes I can click them multiple times trying to see if they are in or out and can’t tell. On cutouts that are close together, arrows sometimes appear in, or overlap, an adjacent cutout. I am going to play with screen resolution and see if that might help.
I try to use the toolpath image shown after Simulation to make sure they are all good. Still had some slip by and cut on the wrong side.
I also recently made a thread to show when I was working off-line, I had a new appearance to my toolpath that helped. Got no explanation as to why the image changed.
