Thank you both S3D-Alex and dkightley.
You are certainly right, I couldn´t explain how I missed the outline overlap as reason for this.
Increasing the overlap certainly solved this problem for me.
Just an idea...
Why not making this a feature?
Where there is need for 40%-50% outline overlap for infill why not just give the option to use single extrusion instead.
Should be "easy" to programm, single extrusion already exists, where there is a gap, say nozzle zize or smaller,
let the software treat the number of walls where there are solid layers determined as "infinite" and force single extrusion fill.
Makes a nice surface and faster printing speed...

If, alternatively, you wanted this filled with Single Extrusion Fill then you would have to use 3 perimeters in this case. Single Extrusion Fill does not replace Infill or Solid Layers but replaces perimeters. With no perimeter to replace there will be no single extrusion.
That obviously isn´t quite right..
Take the factory file from above and increase infill overlap from 20% up to 25% and..... Voila!
S3D is exactly doing that! Closing the top layers with single extrusion.
Easy solution to play with the infill overlap, but that a setting I hadn´t had to mess around until now...
Thank you both for leading me the right way.
