For example, having a print do:
Layers 1-12 at 0.3mm
Layers 13+ at 0.1mm
This would speed up fine-resolution prints immensely - allowing the bulk of printing to be done at a low resolution then switching to a fine detail resolution when its really needed (e.g at the top of the print - where the detail is).
implementation would be the same UI as the Per-Layer fan/temperature set points.
p.s. I know this has been requested before, but in 2018 and 2017 respectively: its been a while
