This is probably not a new question, but I didn’t spot it looking around…
I have a new Shapeoko XX and I’m trying to carve a box with sung fitting top/bottom. As a Test I cut a couple of circles in pine, one contour on the outside to produce a “plug” and a pocket or contour on the inside to produce a hole. I’m using the supplied 1/4 inch mill. The cuts look clean and I was hoping for a snug fit but there is quite a bit of slop (.02 to .03 in) between the plug and the hole. When I measure the width of the cut is is ~.265 which seems to account for the gap.
So I’m assuming this is normal? If so, do I just add an offset to get the parts to fit better?
