The problem is that PrintObject support generator is only run when m_layers.size() > 1, so one-layer object will skip it.
It apparently never worked, after recent refactoring (probably 8bfc986) it started to crash in GCode generator.
This commit fixes the crash, but not the problem. The raft is still not generated (like in all versions since 2.0.0 at least).
The issue was handling of the special "default_filament_profile" vector,
which is not being normalized in length to the number of extruders,
as this vector is being shown to the user at the Printer dependencies page,
and we don't want to present empty fields there, if the default filament
profile was not defined in the system preset.
Fix of #5007 - "Reload from disk" causes objects converted to inches to revert to mm
1) Storing and reloading the "source_in_inches" source flag from AMF and 3MF
2) When converting objects with mixed "inches" volumes, do the right thing
and do not convert those that do not need conversion.
This is a fix of a bug, which was in Slic3r forever, where raw slices
were not cached, but recalculated from classified regions, where
merging the regions did not produce the original contour reliably.
Fixes [2.3.0-beta2] Odd bad slicing related to infill (?) percentage #5407
Replaced all "unsigned long long" types with uint64_t.
These "new" types better communicate their meaning and they are
guaranteed to behave the same on all platforms & compilers.
(linear tapering of extrusion rate for the 1st spiral vase layer)
Linear tapering could only be implemented for relative extruder distances.
For absolute extruder distances, all the G1 Exxx in all spiral vase layers
would have to be adjusted, which is much more complex and risky to do now
before release.
above the solid infill. Should fix
first layer of vase (after bottom layers) is bulging (0.6nozzle, 0.4 layerhight) #3712
Adjust flow of the "second" layer in spiral vase mode #2795
(non-spiral vase layers) were being closed.
Fixes Bad slicing in vase mode (unexpected bridge and solid infill layers) #3326
Fixes Model with holes in the base does not slice properly in "Vase Mode" #5359
