Expected behavior

I was running some tests for cutting mylar. I used the basic circle tool within Luban to do some quick cut tests, and the edges of the cut kept looking terrible and I noticed the unit was making odd noises as though it were cutting a lot of angles, not a round circle. I checked the preview close-up and, you can see that Luban's circle is not actually a circle. I imported a vector circle as an SVG file to compare.

Luban's drawn circle makes for a very poor cut on something as delicate as mylar! I am not sure why it isn't actually a circle.

Thanks!
