The CI Fiber post selected G42 for every perimeter. Cincinnati's CNC Codes Handbook defines G42 as "product remains on the left", and imported perimeters run clockwise with the part on the right, so the controller offset every outside edge into the part: parts came out a kerf undersize. Cincinnati's LaserNST samples only use G42 because they cut perimeters counter-clockwise. Winding is normalized only at DXF import, so the post can't assume a direction either. It now takes the largest contour as the perimeter (as ShapeProfile does) and picks G41 or G42 from each contour's actual winding. That also stops a reversed drawing from swapping the L2/L4 lead-in macros. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
