- removed skinnydip_unloading_speed, unloading_speed is used instead
- the new parameter wipe_tower_extra_flow now automatically adjusts spacing
- the extra flow is seen in the preview
- skinnydip moves were simplified
- for MK4, pressure advance is kept for ramming and disabled for skinnydip
- G4 S0/R were swapped
- for MK4, the new temperature is set before the last cooling move
- range of the ramming dialog increased to 60 mm3/s
- fixed skinnydip_extra_move
- fixed temperature setting after cold_ramming
The crash was introduced in 040a846, which completely threw away handling of the return value
of the importer.load_model_from_file function and replaced it with weaker condition. The purpose
of that change was to solve #8401 (missing error message when loading different invalid 3MF).
This commit reverts that change (and reintroduces #8401). Handling of 3MF loading errors
should be inside the importer.load_model_from_file function, where the check should be
added later.
Previous algorithms assume that they can get an invalid Voronoi diagram. Because of that, during the multi-material segmentation, a copy of the Voronoi diagram was created, and there were several attempts to fix missing vertices and edges. But as it shows, this wasn't a good enough approach and sometimes led to several issues like bleeding layers.
After generalization, our approach for detection and repairs of invalid Voronoi diagrams from Arachne, we could assume that multi-material segmentation gets non-invalid Voronoi diagrams.
With this assumption, we reimplement multi-materials segmentation to work directly on the Voronoi diagram. That should make multi-material segmentation more stable.
So, this should fix several issues like bleeding layers. Also, memory consumption should decrease by a lot. Also, there should be some speedup of multi-materials segmentation.
