Reply To: Milled holes undersized – any ideas?

So I finally got time to use the machine again, and decided to make a test piece to make one piece of wood (pine) fit into another. The outline of the pine cut out ok, although the milled pocked is not square (as per ESTLCAM view). I also noticed one side of the cut out wood was a bit wonky, rather than a nice clean cut. I raised the work piece up, and it didn’t seem to be struggling to cut.

I was using a 6mm bit, 4m DOC, 12mm/s feed speed, 45%, 180 degree and 700w router – anything stupid about those settings? I’ve attached some photos to illustrate.
