Crop circles ?

Usually occurs when there is a gap that is too small for the cutter so the toolpath takes "the long way round", make sure all gaps are at least the size of the cutter plus twice the amount of any material left on for a finish cut.

Also known to come from a malconfigured post processor in older versions.

Need build version and possibly post processor depending on when the circles appear (from code, etc)
