Toolpath generation issue

Confirmed — it passed the full geometry suite (all green), so the fix is in.

Cause was exactly the arc-fitting case I mentioned: on that panel one contour has a long, very gentle curve, and during the kerf offset the fitter briefly mistook a tiny cluster of points on that curve for a full circle — that's the phantom you got. The guard that should've caught it couldn't, because those points barely move, so nothing looked out of place. I tightened it so the fitter now rejects any arc it can't back up against the real cut path. Every contour on your Camping panel 3 file cuts clean now, and the keyhole/tangent cases are untouched.

It'll be in the v2.3.9 pre-release — I should have that out later tonight. Thanks again for the file and the machine config — that's what made it reproducible. Sorry again about the 10ga.

Regarding the lost plate, no worries, it happens. At least I didn't make a boo-boo on 1" plate, ha. I need to keep in mind that I'm running software not familiar to me, and take more time to look things over before heading to the table to cut. Thanks for looking into this and fixing the issue.

I happen to have the panels in both DXF and SVG format from the seller, and to cut a replacement panel I nested the SVG version of the same Camping 3 panel into an available spot on the sheet and that one worked for me.

I'm not surprised that the SVG didn't reproduce it because the underlying base geometry is inherently different even though it forms the same visual path. SVG's don't hold arcs like a DXF. Glad I could sort it out!
