Slic3r top layer issues, small gaps, weird extruder paths When slicing with Slic3r Prusa edition the top layer of most models turns out pretty bad. There are usually small gaps or weird patterns. This does not happen with Ultimaker Cura, it will have a nice smooth top layer. Is there anything settings wise that I can do in Slic3r to get the same quality of top layer as Ultimaker Cura?
To have a very smooth finish on top layer, I usually act on these settings :

in Print Settings :

Layers &amp; Perimeters :
  Horizontal shells : 3 / 3

Infill:
  Infill, Top/bottom fill patterns : Archimedean Chords ;

Speed:
  .for print moves :
   Top solid infill : 20  (mm/s)

Advanced:
  Extrusion width, Top solid infill : 0.2 (mm)


= This gives very slow movement in a circular way, the small extrusion creates an ironing effect, thus very nice finish.

Considering your slicer behavior, have you tried changing number of top shelves &amp; Infill type ?
