infill behaviour: program creates problematic lines

[mountainmax]

Hi there,

hope you can help me with the following:
Recently the program creates some lines to the file that I can't remove. Those lines always appear at the boundary between perimeters and infill structure and they seem to be some kind of gap filling. You can find them highlighted in the attachment (those wavy lines). I recognized some similar behaviour when I sliced a construction with thin walls, but in the recent case the wavy lines don't exist in every layer. There are some layers with almost zig-zag lines, some with wavy lines and some layers without the problem.

I really want to remove the lines, because my printer cant handle such tiny structures.

Greetings,
Max

It looks like these are probably Top/Bottom Solid Layers but it is tough to tell from just the screenshots. Could you provide a Factory File please?
