- Extrusion width 0.5 (and it is confirmed to be extruding 0.5047 mm).
- Allow gap fill when necessary
- Allowed perimeter overlap 50%
- Perimeters 2
Since my overlap is 50%, I expected the perimeter infill to come in much earlier, starting at 1.25 mm thickness as the diagram below shows:
The above diagram is my understanding of what S3D should be doing. We've got three cubes signifying the perimeters. The middle perimeter (brown) overlaps the outer perimeters (blue) by 25% on both of its sides, leaving 50% of the middle perimeter not-overlapped.
Instead, this is what we get. A gap between the layers, which is the opposite of an overlap!
Could we please get either a fix or a better explanation of what gap-fill is actually doing? Because it's clear that "Allowed perimeter overlap" should probably be renamed to something like, "Preference for interior perimeter".
