I was told that there is a good way to align the Z axis, but haven't found the info. The bottom of a flat end mill is not parallel to the bed, so when cutting along the X or y axis, one edge of the cut is deeper than the other. To me it looks like siding on a house. Does anyone know a procedure to square it?. Hopefully a better way
than jamming tiny wood shims between the spindle and the mounting plate?
