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)
- wipe tower respects max volumetric flow, slowing down with PVA etc is not hardcoded anymore
- wipe tower is now allowed for multiple-extruder printers. single extruder stuff is not used in that case (ramming, cooling, etc.)
- start/end filament and toolchange custom gcodes are now inserted differently than before - see 41164a9
- some refactoring, e.g. the abstract WipeTower class was eradicated
- abstract class WipeTower and its descendant WipeTowerPrusaMM were merged into a single (non-abstract) WipeTower class
- all uses of WipeTower::xy struct were replaced by Eigen Vec2f (it is no longer necessary to be independent on libraries that PrusaSlicer uses)
- the WipeTowerPrusaMM.hpp/.cpp will be renamed in the next commit (hopefully it will retain its git history that way)
no longer necessary because the speed overrides that the enum controlled were recently removed
the comment in gcode is now just about appending the config string
The priming extrusions were handled separately from the rest of the wipe tower toolchanges. In order to be able to use the logic from previous commit for them (custom toolchange gcodes etc), some unpleasant code shuffling was needed
- setting of the wipe tower parameters based od whether SE MM printer is selected is done in the WipeTowerPrusaMM constructor, so it does not distract in Print.cpp
- WipeTowerPrusaMM.cpp conditions checking for SE MM printer are now using a more descriptive const member variable, not the loading/unloading speeds (hopefully the functionality is the same)
The odd commands that lowered the speed override values for PVA, FLEX etc. were removed
Now the wipe tower backups user speed override, sets it to 100%, does what is needed
and restores the old value when finished. There are no special cases - lowering
the speed for certain materials can be achieved by lowering the volumetric flow.
There was a bug in unit tests that led to generating the wipe tower with non-normalized preset.
This caused out-of-bounds access into max_layer_height vector in fill_wipe_tower_partitions.
The problem surfaced in https://github.com/prusa3d/PrusaSlicer/issues/2288.
I quickly patched additional normalization of the preset to prevent this from happening.
Also, an assert in the same function turned out to trip on one of the tests.
This one was commented out for now and will (hopefully) be looked into later.
Function Print::apply_config was renamed to apply_config_perl_tests_only so everyone
sees its current purpose and does not mistake it for the more important Print::apply.
Refactored ModelVolume::Type to enum class ModelVolumeType to be able
to forward declare it.
Refactored UI to use the ModelVolumeType instead of the untyped int.
Fix of SLA gizmo picking by rectangle: point is occluded only if an object
is half its radius away from the point center.
Don't show the temp G-code file name in the status bar when exporting.
from the current Model/ModelObjects.
Fixed a possible race condition in updating Print::m_placeholder_parser
with the proposed filename / filename base.
Improved documentation (source code comments).
Multi Material prints & soluble supports.
Disabled assert testing for the existence of "printer_technology" fields
as it triggers on loading of legacy AMF/3MF files.
Added a new validation into Print::validation() to verify, that
the non-soluble supports need to be printed with "current" extruder.
This check was already there, though for the global parameters only.
Now the check is performed inside the Print class for the object
override parameters as well.
Improved the Print::validate() handling. The Print::validate() is only
called if the Print::apply() indicates a change, or if the slicing
was executed by the user explicitely (with the "Slice now" button,
with the "Send to octoprint" button, or by switching to the print
path preview).
