Well it sounds like your calibration is OK.
Being a struggling programmer, I mostly stick with steppers
and haven't had much servo experience I'm afraid. Have you tried on the Mach forums? Either Here:

I know you mentioned IJ mode, but just to be double sure, you are using the same ArcCenter mode in CamBam as in Mach?
Constant velocity mode might be another one to check. Try setting CamBam's velocity mode property to ExactStop or change your gcode to use G61 rather than G64. Not sure if this will help, but it may help rule out another possibility.
Last thought for now... what Mach kernel speed are you running? For servos you should be running at as high a kernel speed that your PC will reliably support (as far as my limited understanding goes).
Hang in there... I'm sure you'll crack it!

One thing I failed to mention before, is one quadrant of the circle had a protrusion at the 10:30 position of +.020 when the rest of the circle was equal. I came across an article with respect to this issue. Perhaps you are familiar with it (link below). I will review and re-think. Maybe that proverbial light will come on. Let me know if yours does. Thanks!
