Makercam Issues - Cutting Holes

I am working on my very first project with my new Maslow and I’m having difficulties cutting some holes. I have 36 different parts with .406" diameter holes, and they cut perfectly. But with one other part, the .406 diameter hole doesn’t cut correctly. Attached are screenshots of the two different holes as they shown in Ground Control. I’m new to all this so I figure I’m doing something wrong. Any Ideas?

Makercam is dead, based on Flash which is gone or being removed in most browsers. Flash is the exploited bug infested scourge of the internet these days, the mighty has definitely fallen.

I use Carbide Create (workspace recently expanded to full sheet size, 48x96 or metric equivalent) but there are a number of alternatives.

Thanks. I’ll try that…
