Aforww makes some great suggestions too. I ran your bore settings on one to make sure there were no glitches. Worked fine, was about 0.05mm (0.002") out of circle and was about 21.95mm x 21.90mm versus a 22mm model. That's not perfect but for practical purposes pretty reasonable. Some of my undersize error could be that the end mill doesn't equal the nominal value. I pressed in a 22mm OD bearing without much effort.
The CAM settings are fine. Do check on Aforww's suggestions and try the square test too.
I'll see if I can post a pic. Coming in too big from my phone for direct attachment.

Finally, my circles problem solved!
It was a combination of things but mostly a lack of belt tension. When it was mentioned that the belts where supposed to "pluck", my didn't, and I was shocked how loose they where. I tightened up the X and Y belts and that made the belt feel super solid. Then I noticed a lot of play in the spindle head, looks like I never tightened down the Z rods when I swapped in the new spindle. After locking all that down I can finally say I'm getting "perfect" circles!!!
Thank you everyone.

Just out of curiosity, what are you making? That looks like a face for a gauge pod.

Just out of curiosity, what are you making? That looks like a face for a gauge pod. Practicing making "Fidget Spinners". (2x) 22mm bearings on the outsides for weight and a ceramic 22mm bearing in the center. Place thumbs on center bearing and flick the spinner!

Ah yes. I have a couple designed up in Fusion but haven't cut em yet. Maybe that's what I'll use my trashed HDPE I wanted today for lol.
