psWipeTower now equals to new psToolOrdering indicating that
the ToolOrdering has been calculated (only if non-sequential mode is active).
psBrim now equals to new psExtrusionPaths
psExtrusionPaths shall be the last step before psWipeTower, indicating
that all the printing extrusions are calculated for the G-code preview
slider to edit the custom per print_z color changes, tool changes etc.
Refactoring of GCode export of color changes, extruder switches etc,
so that the "color change" like extruder switches are applied first
at the Wipe Tower / G-code export, so that adding / removing
an extruder switch at the G-code preview slider does not invalidate
slicing.
If the Elephant foot compensation is applied to the 1st object's layer,
the uncompensated 1st object's slice is newly used for calculation
of bridges, overhans, skirt, brim, raft and supports.
Layer::slices were renamed to Layer::lslices to simplify reading
of the code, to differentiate from LayerRegion::slices.
Fixed layouts after the second opening of the dialog.
(Removing any extruder from the sequence does not cause an incorrect layout)
Validation of entered values added
(0 is not a valid value)
Layer newly remembers bounding boxes of slices,
the bounding boxes are used by G-code generator & newly the support
generator.
Slices are stored as ExPolygons, not ExPolygonCollection.
This prevents a crash when the print is empty and the wipe tower enabled - validation of the wipe tower attempted to access extruders().front(), which was empty.
No other checks need to be done with the empty print anyway.
of the Z coordinate, compiled in the ClipperLib_Z namespace.
Update of Lukas's new brim clipping:
All the brim contours are now clipped by the ClipperLib_Z library
in one shot.
- added an extra travel move after a toolchange
- wipe tower only sets temperatures with single extruder MM printers
- ooze prevention does not work with the wipe tower - added a check into Print::validate()
Changed messagebox text after changing extruder diameter with single extruder printers so it is more obvious why it shows
In case nozzle diameters differ and someone checks 'single_extruder_mm', PrusaSlicer asks whether all diameters should be unified. Answering NO did not undo the SEMM check. It does now.
The initial priming now does not assume anything about bed width and always uses the space it has
In case of circular beds it places the priming lines along the diameter
Custom beds are not supported (they are treated as circular with no extra checks whether it is sane)
Slight refactoring of the WipeTower class (constructor now gets reference to PrintConfig and not the individual values, same with set_extruder). This was legacy from times when the wipe tower was meant to be abstract and independent on the rest)
