has portions that do not go as deep as they should and the starting z height is higher than it should be for approx. 2.5 inches and then it drops to the correct height
I do a roughing pass with a .5 endmill and a finishing with a .25 ball nose at 7% stepover.
I should have also noted before that even though I set the gap above model to 0, there was a z drop on the top of the surface at the very beginning of the file.
