Ron, if you consider 'simply complaining' my description of the defect, then so be it... I remind you that you admitted that circle cutting had a coding error and you would bring it to Brian's attention; I call that a bug report. I have attached the job file in this case, perhaps you can explain what I did wrong, and/or weather I defined the problem insufficiently, and finally how to execute the operation correctly. The material thickness is 0.77"
Thanks,
Roger
