Rough stuttering on part of cut

Just did a vcarve with circles just fine.
Now trying to do a cut at .05 per pass, and it will go almost all the way around fine, but when it comes around this corner, it starts stuttering and knocks itself out of being homed.

When not cutting, I can move it at full speed in any direction with the controller.

This file was traced from an image, using Carbide Create, but I checked the nodes and it doesn’t seem like there are too many or anything that would cause the issue.

The red part is where it starts stuttering -

It must have been the file. The original came from a PDF.
I recreated the shape myself and it worked fine.

Sometimes you get some very small line segments or small zig zags that are barely visible that can cause the odd movements. Also some CAM systems may turn a radius into hundreds of small line segments that will give similar movements.
