Possible problem when slicing gyroid infill near fillets
The image is of a part I printed with a fillet on an edge of the bottom surface. Normally this prints fine, but this time I used Gyroid infill.
I noticed in the slicer that it just lined up so that one of the wavy lines of the infill ran right next to the edge of the piece, and when it does this I think it messes up the outer surface.
I suspect that having the wavy infill intersect the perimeter means that it is being pulled unevenly as the filament cools and is bending the perimeter in and out along its length.
Perhaps the slicer could attempt to avoid running gyroid infill right along (intersecting with) perimeters for any significant distance?
I printed 4 of these parts on my core one and all has exactly the same issue (and ever other bit of the part was flawless).
Best regards,
David
