Thanks but I don't know what you mean by "true circles".
True circles are circles created by the circle tool.

Could it be something in my controller?
If by controller you mean your CNC machine's controller then no.

I've tried recalculating the toolpath and a higher resolution.
I think we're talking at cross-purposes here. Recalculation is not referring to altering the circles but by editing the toolpath and clicking on the calculate button (or by right-clicking on the toolpath's name and choosing the menu entry "Recalculate").
The following image shows what happens if you use the "Curve Fit" tool to replace the circle with straight lines with a tolerance of 0.75mm. You get a heptagon.
When you calculate a pocket toolpath using that object you get the following toolpath shape (with the heptagonal shape):
If you delete the heptagon and replace it with a "true circle" and
do not recalulate the toolpath using the new vector you get this preview:
Looks suspiciously similar doesn't it?
This is that same circle recalculated (anomaly disappears):
Attached is a file with the following four "circles":
- Circle created by the circle tool ("true circle")
- Circle "Curve Fit" to Bézier curves
- Circle "Curve Fit" to circular arcs
- Circle "Curve Fit" to straight lines (0.0254mm tolerance)
There are two toolpaths (your original pocket and profile toolpaths). They have not been calculated so they will not show any preview.
I'd suggest downloading the file. Then recalculate all toolpaths. Does the privew of the toolpaths show the anomaly in you original file? If it does then there is something wrong that is going to be difficult to diagnose.
By the way: what version of VCarve are you running. You find that be selecting "About VCarve..." in the help menu.
