Circles with a blip

[Azpark]

Using the drill tool to cut 2 circles. One is 2.75 dia. the other is 2.375. Looking at the attached picture both circles have a blip. Any ideas whats causing the blip?87486

My first thought would be something is loose. Wiggle the bit by hand to see if there are some loose bearings on the truck. Did the hole diameters turn out right?

Or maybe zoom in that area on your pattern or try "Toggle Non-endpoint".
You may have inadvertently left a stray node in your design.

It may have been a stray node. I started from scratch with a new board on the computer and the blip disappeared.
