Thanks for the replies. I am typing "2.5" for a 5 inch ball. It could be a setting in the software Danny though it could just be the software. I'm importing it into BobCAD. I'm going to ask over there to see if there is somthing controlling a tolerence or the likes. Just needed to be sure there was no accuracy setting with MoI.

Danny, Have you had any experience with OneCNC or heard anything about them. I may need to look at something in the future.

Thanks again,
Burr
