What can be the explanation for these gaps in the infill?
Sliced with SuperSlicer. Infill speed was 225, perimeters 160. Slowed it all down to 80%, making infill 175 and perimeters 130, to see if it cleared up, but it didn’t , even though the initial perimeter speed is about the same.
Flow on the infill was at first about 20 mm3, after slowdown about 15 mm3, with a Mosquito Magnum and Orbiter 2.
Edit
Also tried the whole print at 150, gaps are still there. But less then before. Perimeters at 150 are fine.
