I am still having issues with some of my top surface fill areas being too sparse, even after increasing my extrusion width from .40mm to .48mm (same value as auto). I am also seeing a pretty noticeable separation between each of my 3 outline shells but not sure if that would be considered "normal". I'm printing at 0.10mm layer height in PLA and have set my speed multipliers pretty low as well to ensure a good quality print.
Aside from the extrusion width should I also try bumping up the extrusion multiplier from 1.00 to maybe 1.02? I finally purchased some digital calipers and this filament averages around 1.78mm although I've not changed my settings in S3D from the default 1.75mm. My assumption is that if I INCREASE the filament size setting then the printer will extrude LESS plastic...which would make my gap issue even worse???
Here is an image that might better illustrate what I'm seeing...
Thanks,
