I’m also a novice, and I studied physics in college, so be careful of my hairbrained ideas.
In the case of my cabinet door (https://www.v1engineering.com/forum/topic/mpcnc-cabinet-transformation/) it did most of the pocketing first, to a depth of 3mm (IIRC, I can’t remember). After removing all that material, I think the door bent up a little, and it ended up just 0.1mm or 0.2mm higher in some places. Then, it did the fine tracing around the edges (again in 1mm passes) but since it had bowed up, it dug a little deeper, so the traces around the edges are deeper than the pocketing. Oh now that I look at my post, it was to 1.5mm. I bet I did that in one pass. I should have done 1.4, then a 0.1 cut or something.
My thoughts on this were that if I did a pocket to almost the full depth, and then did another cut, just a little deeper, then it would remove enough to clean it up, but not enough to cause more flexing. Then the trim passes would go to the correct depth. I could do that by making my final depth slightly deeper (3.1) or make each pass slightly less (0.95mm/pass, then it would be at 2.85mm, and have to make another 0.15mm pass). Even easier is probably to just make two tool paths, one to a depth of 2.85, and one with a depth at 3.0, starting at 2.85. That would probably do them in a better order too.
That bit shape definitely exaggerates things, I understand better how some of those marks are made.
