The before and after on my toolpath cleanup was night and day
I spent like 3 hours last Tuesday just organizing my toolpaths on a job for a marine part out of 6061. Had this nasty gouge on the final pass every time before, like a deep scratch right on the finish surface. Turns out I was using a leftover roughing path that was overlapping the finish pass by about 0.02 inches. Cleaned up the sequence, added a small 0.005 finish allowance on the rougher, and the final part came out smooth as glass. Anyone else ever have a tiny overlap mess up an entire surface?

That overlap sounds like a classic case of the roughing pass leaving a witness mark.

Wait, you've seen that too? I swear I thought I was the only one who kept running into this exact problem. It's like no matter how careful I am with the roughing pass, that little line always shows up right where the passes overlap. I've tried changing my stepover, different tool paths, even adjusting speeds, but that witness mark just laughs at me. The worst part is when you think you've finally got it clean and then you hit it with the finish pass and there it is again, taunting you. Honestly props to you for spotting it, most people just blame bad tooling or something.
