Implemented long unsupported segments detection, which considers also curvature
Implemented detection of curved segments at the edge of the previous layer - danger of warping/curling
Now Lightning infill will ignore this setting and treat it as off. Because Lightning infill and "Only infill where needed" do a similar thing, and their combination doesn't make much sense.
That allows computed better values in cases when the extrusion width of the first layer or for the infill differs from the extrusion width for perimeters.
Parameters min_feature_size and wall_transition_length now can be set in percentages, and then they will be calculated based on nozzle size. Old profiles with default values are forced to replace old default values with new default values in percentages.
Fuzzy skin will be disabled for regions with
with fuzzy_skin_point_dist < 0.01 or fuzzy_skin_thickness.value < 0.001
as the first one creates excessive long extrusions while the second
one does not modify the perimeters.
With solid_infill_every_layers = 1 the new solid layer should be solid
infill not solid bridging infill. Once the layer is correctly classified
as solid with solid_infill_every_layers = 1, everything works as expected.
For this particular model, ClipperLib numerical instability causes
one of the internal surfaces to turn into bridging surfaces
on reslicing. The issue was fixed by reverting to untyped slices if possible.
When propagating overhangs to be supported, the regions are newly
properly merged and regularized.
Fix of Stuck at "preparing infill" with "only infill where needed" enabled 1.41.2 #1696
"Only infill where needed" makes slicer crash for some models #6385
[BUG] Slicing stuck for 14h now, 0.8 NZL Ender 5+ Gyroid infill only where need
support blockers / enforcers.
All slicing functions shall produce consistent results with the same mesh, same transformation matrix and slicing parameters.
Namely, slice_mesh_slabs() shall produce consistent results with slice_mesh() and slice_mesh_ex() in the sense, that projections made by
slice_mesh_slabs() shall fall onto slicing planes produced by slice_mesh().
Before this commit, slice_mesh_slabs() projected bottom facing faces upwards to its coplanar slicing plane,
which is different from how slice_mesh() or slice_mesh_ex() work, leading to ignored support enforcer / blocker strokes.
