Over six months with my 32 I'd noticed that my through-cuts seemed consistently a bit shallow... I almost always had some "skin" at the bottom. So this weekend I did a few quick tests.
Sure enough, it turned out that on cuts from 1/4 to 3/4 deep I was about 0.5 percent shallow (e.g., a cut that should have been 0.5 deep calipered at 0.496). Same factor seemed to apply, roughly, to X and Y... although I didn't mic my 1/4" mill, so that might be just a tooling variance.
Has anyone else seen consistent small errors on this order? And if so, is it worth adjusting the Bot's setup factors, or should I just apply a correction factor in the fill-in sheet each time I go to cut?
