Looks like your parallel finish pass hasnt been run yet?
The tooling marks look like 3D roughing. - Oh, I see, your “Stock to leave” setting in your roughing settings was set too low - Typically .01" is the default I believe.
You need to leave enough material on the part for the parallel finish pass to be able to grab.
On your Finish pass the stepover should be 1/10 the cutter for a fine finish.
