I have a simple part that has an inner hole and ellipse shaped outer. When I machine the part I'm seeing each x/y move in part (see picture). I've tried smoothing, using R vs IJ and it some cases seems a bit better but still not acceptable.

If you look at the picture you can see the small moves (keep in mind I've gone over it a few times and you can see tool marks). But the individual steps I can't understand. I even thought maybe it's the machine but notice the hole in the center. Absolutely perfect.

Please help

Could you share your file here? It's not clear from the clipped image of your browser what toolpath may have left that mark.

I think I see the problem. I exported my ellipse as a .dxf and opened it in BobCad and what you see here is what the machine is doing. The outer ellipse I added using BobCad.

BobCad....watch your language 😉

Seeing the (Fusion) file would help us to determine if an old bug has popped up again, please share it if you can

Believe me, I left Bobcad a long long time ago. Fusion has been awesome.

Here is the file- btw, I could not include the file as an attachment.

These black dots represent toolpath points, Before and After:
