Different layer height for perimeters

Allow the outermost perimeter to be a different layer height, ie outermost being 0.1mm and all others being 0.2.
this will allow the increased print speed of the larger layers but without sacrificing much in the way of speed to still get the quality of the lower layer height.

Interesting idea. I’ve seen interstitial layer mapping based on multi-extruder machines. I could see how this suggestion would make for fine print quality without sacrificing time. The slicer would have to manage backing for the second layer where you begin making sloped top surfaces.

i had already made the suggestion.
