I'm at 5 layers now at .2mm layer thickness (1.0mm top layer total thickness). Referencing examples top layer thickness:
1. 2.0mm
2. 1.0mm
3. .75mm
4. .4mm
After adjusting top layer thickness I moved on to other settings. The thinner layers did help better than any other single adjustment, however the infill pattern began to show through (sample 4). Grid infill with 1.0mm top thickness was my compromise. I might revisit but I'm going to try a Monotonic order and maybe Ironing next.
