Linear advance is reset by filament start gcode after a toolchange. However, not all moves to the wipe tower
end with a toolchange (brim, empty grid) and it would therefore disable linear advance until the next toolchange
This should solve https://github.com/prusa3d/PrusaSlicer/issues/2770
Reported in https://github.com/prusa3d/PrusaSlicer/issues/2752 and was a result of setting support contact z distance to negative value.
This lowered the maximum allowed print_z of the next layer, even though previous layer had object layers too, so the penalty from the contact z should not have been applied.
Fixed simply by rejecting the negative contact_z.
That could happen on empty support layers which do not necessarily matter, since their spacing is not generally synchronized with the object
The new hopefully correct logic is "if there are extrusions on a layer, check that last layer with extrusions is at most the new layer height below
This is a fixup of changes from 0de6e53 and 6ab1cec
for the GLVolumes before sending to the GPU driver. The following commits
were partially reverted:
4269c8b23c Removed GLVolume non-VBO rendering
d15698e21e GLVolume and GLIndexedVertexArray refactored to send data to gpu at the first render call
Namely, the GLVolume buffers are "shrink to size"'d before sending their
content to the OpenGL driver, and the vertex buffers are populated
as quickly as possible from the GLVolume, so that the same buffer is not
kept twice in RAM on systems, where the RAM is shared with the graphics
card.
Also the memory allocation reporting was improved for the GLVolumes.
Added detection of empty layers so the wipe tower doesn't trip on them (it is not printable anyway).
This should improve wipe tower reliability with supports, objects standing on edges, etc.
I also turned an assert into exception throw to prevent hard crashes and nonsense output.
- 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
These firmwares use M135 Tn and M108 Tn commands for changing active tool, which the analyzer did not recognize. The toolpaths were then rendered in wrong color, extruder offset etc. This surfaced in issue https://github.com/prusa3d/PrusaSlicer/issues/2566
Integration of the "cereal" serialization library.
Serialization / deserialization of the DynamicConfig / DynamicPrintConfig.
DynamicPrintConfig serializes ordinal identifiers instead
of the option key strings to conserve space.
- 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)
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
Each toolchange now emits:
- end filament custom gcode
- toolchange custom gcode; if not provided, a standard Tn command is inserted
- start filament gcode
Hopefully it is now consistent for SE/ME printers with/without the wipe tower
The priming line does not work - will be fixed in the next commit
Missed adding [total_layer_count] to layer_gcode
Revert "Add new [total_layer_count] placeholder everywhere [layer_num] is avalible."
This reverts commit e29e766224a14e1f237908c3e5507ac5586ca5b7.
Revert "Missed adding [total_layer_count] to layer_gcode"
This reverts commit f07907a8acc450e9ae1220c6a9fe4f7c7e6d896c.
Better way to add [total_layer_count]
has been rewritten to be easier to parse.

Fixed a possible race condition in updating Print::m_placeholder_parser
with the proposed filename / filename base.
Improved documentation (source code comments).
This is a fix of a long standing bug, where an extrusion is incorrectly
drawn from the end of the last wipe move. Interestingly enough,
this bug is in Slic3r at least since 1.2.9, but lucky enough
it only occured for single perimeter, no infill prints with wipe after
retract enabled, and only if the two successive slices were discretized
exactly the same, which is quite unlikely.
by PrintObject::region_volumes. This is due to the way Print::apply()
works, it does not invalidate an existing PrintObject if a new region
is added to the print.
