My bit is not cutting all the way to the edge of its path. The simulation shows it cutting all the way to the edge. Please see my images to see what I’m talking about. I already tried to make my stepover smaller, no luck, same results as the first print. Any suggestions?
This happens sometimes when stepover is high and an integral number to the width of a given area.
Usually adjusting the stepover will allow one to get more even spacing which eliminates the gaps.
A better bottom finish can be achieved by adjusting the depth per pass so that the final pass removes a very shallow thickness of material, e.g., for a pocket to 0.5" w/ a depth per pass of 0.125" which makes for 4 full-depth passes, instead change it to 0.124" which results in 5 passes, the last removing only 0.004" of material.

This is my current settings without any changes. I’m focusing on just the Mustache and once I figure that out, I will move onto the other sections. With this info, what do you think I should change?
I adjust stepover until I get a reasonably even appearance in the spacing of the lines.
With the power on, but the spindle OFF, grab the collet and try to wiggle it around. It should feel ‘locked’ in place since the power is on.
If there is any movement or play, then you have a mechanical problem.

Is the remaining material a consistent thickness all the way around? If so, make sure the actual bit diameter and the diameter in the tool database match.
If it not consistent, that would more likely indicate a mechanical problem.

It looks like the remaining material is on the right & top sides on all of the features.
This would indicate that the tool/machine moved somewhere between those 2 toolpaths.
This would be the first issue to tackle. (All screws, belts, drive gears, stepper motors, tight & secure)
I think you would benefit from a different strategy as well. Instead of just cutting the top of the ‘mustache’, cut the entire level. So (a really crude example)
Cut everything down to the top of the mustache
Then cut everything from that height to the bottom
