[Need TECH Help!]

So i once thought that some of my rough finishes on angles might be do to my linear rails needing replaced on my Hurco Mill.(https://www.cnczone.com/forums/dynom...-software.html) But have recently replaced them. And now iam making an aluminum part that is octagon shape with 45 degree walls. All the walls that are inline with X or Y axis have a nice finish but the walls that are 45* have a rough finish, see pics.You can easily feel High and Low spots with finger. The walls are .425" tall and iam using a new carbide .5" variable-helix endmill.
Could this be my settings setup in the Trajectory Planner Screen?
Here is Gcode.
