Any ideas why extra "hooks and loops" show up when routing a part outline consisting of a series of arcs? I've been routing about 15 or 20 different outlines
(guitar pickguards) successfully, then suddenly a new wrinkle shows up. Cad files are created in Flexisign, (poly line curves) exported as .dxf, to BobCad, .dwg, cleaned up to make arcs tangential and features more dimensionally correct, then BobCam to generate gcode with Mach3 post.
I struggled through lots of learning re. lead-ins/-outs, and issues with tool path offsets (thanks to many good forum posts as resources)
I can't see any difference in the code from other parts of the same outline. I've zoomed in on the .dxf and .dwg drawings and can see no breaks or flaws in the joining of the arc endpoints. I've tried re-starting Mach, reloading code, re-creating code. So far, it's the only drawing to show the problem.
I hope the attached files are enough info for a clear understanding. Thanks a bunch.
