extrude_infill() and extrude_support() reversed the layer's extrusion
entities in place while chaining them, so each export started from the
previous one's reversed toolpaths, and each copy of an object from the
copy before it. The export-time region lists now hold const pointers,
and chaining reverses a clone instead.
Fan speeds, multi-tool ramming, the tower interface and flush temperature
fallbacks and the custom G-code placeholders now use the extruder variant a
filament prints with on each layer, instead of reading by filament id.
Pressure advance, adaptive pressure advance and its model can now take a
different value for each extruder variant of a filament, such as Standard and
High Flow nozzles, like the other per-variant filament settings. Projects
saved with one value per filament apply it to every variant of that filament,
and the addnorth BBL filaments in the Orca Filament Library are updated to the
per-variant layout.
* fix: bounds-check the toolchange flush-volume and HRC per-filament lookups
GCode::set_extruder's toolchange flush-volume lookup and
GCodeProcessor::update_slice_warnings's HRC check index per-filament and
per-extruder arrays (flush_volumes_matrix, the filament map, the nozzle list)
by filament/extruder id. When a config leaves one of those arrays shorter than
the filament count (partial or legacy multi-extruder projects, minimal
configs), the reads run off the end: silent on a normal STL, a hard abort under
_GLIBCXX_ASSERTIONS.
Route both reads through bounds checks: the flush lookup falls back to no flush,
matching the existing unknown-old-filament branch beside it, and the HRC check
skips an unmapped filament, mirroring the required_nozzle_HRC guard on the line
above. When the arrays are sized to the filament count the values are unchanged,
so correctly-specified configs are unaffected.
* ci: retrigger checks
* fix: guard H2C per-filament array reads against short config arrays
The H2C tool-ordering, wipe-tower, and g-code export paths index per-filament
config arrays by filament/tool id. A config with fewer entries than the filament
count (partial or legacy projects, minimal test configs) makes these reads run
past the end of the vector: silent under a normal STL, but UB that aborts under
the flatpak build's bounds-checked STL (_GLIBCXX_ASSERTIONS).
Route the reads through the existing clamping accessors (get_at,
get_filament_category, is_in_same_extruder) and add a small clamp helper for
filament_change_length. The guards are no-ops when the arrays are sized to the
filament count, so correctly specified configs are unaffected.
* fix: size the grouping context's filament_info to the filament count
build_filament_group_context built model_info.filament_info by walking
filament_type, so a config whose filament_type is shorter than the filament
count produced a short vector. FilamentGroup indexes filament_info by filament
id, so clamping the individual reads only moved the out-of-bounds access
downstream. Loop to filament_nums and read all three fields through get_at,
and drop filament_ids entries past the filament count, since the grouping code
pairs filament_ids and filament_info by position.
Adds a regression test with four filaments and one-entry filament_type /
filament_is_support. Without the fix it throws bad_alloc from copying a garbage
std::string read past the end.
* fix: guard the carousel nozzle-change length reads too
The carousel branch added in b90ac13d86/b0dddb4648 reads
m_filaments_change_length by tool id without a bounds check, the same
pattern this branch already routed through filament_change_length_at
a few lines above in both plan_toolchange and plan_tower_new.
* fix: guard WipeTower per-filament array reads against short config arrays
The BambuStudio WipeTower sync reintroduced raw per-filament array
indexing that reads out of bounds when a config leaves an array shorter
than the filament count: m_physical_extruder_map in format_line_M104/M109
(indexed even when empty), and m_filament_categories in get_wall_skip_points
and get_wall_filament_for_all_layer. Silent on a normal STL, a hard abort
under the bounds-checked STL the Flatpak build uses.
Bounds-check the physical extruder map before indexing (omitting the T
token, as the existing -1 path already does), and route the two raw
m_filament_categories reads through the clamping get_filament_category()
accessor the surrounding code already uses. No change for correctly-sized
configs.
* build: remove std::move that blocks copy elision
std::move wrapped around a temporary, or around a local being returned,
stops the compiler constructing it in place. Each edit is the fix clang
suggests, which is to delete the std::move call and keep its argument.
Three of the 39 sites save a move, the two return std::move(local) in
Print.cpp and TreeSupport.cpp:2749. The rest are equivalent either way
and match how the codebase already writes this elsewhere.
Clears 39 -Wpessimizing-move warnings.
* build: drop null checks on references and this
A reference cannot be bound to null and this cannot be null, so the
compiler folds these conditions to true and drops the guard. Seven are
if (&bitmap && bitmap.IsOk()), where IsOk() already does the work; two
test this directly. The guarded code runs either way, so removing the
dead operand changes nothing.
Clears 11 -Wundefined-bool-conversion warnings.
The placement clamps and the tower-approach router both stood in the bed's
bounding box for the bed itself, so on a delta or hexagonal bed the prime tower
could be parked in a corner that does not exist and the nozzle could be routed
across it. Both now test the real printable outline, slicing reports a tower
that does not fit instead of printing it off the bed, and a tower parked near an
edge is routed along the clamped side rather than falling back to a straight
line across the tower.
Also fixes the placement validation rotating the tower hull by degrees read as
radians about the plate origin, and never rotating the generated tower footprint
at all.
Adds a printer option that picks up the new tool without a blocking temperature
wait, travels to the wipe tower, and waits there right before purging, parked
beside the tower so the ooze from the heat-up lands next to it rather than on the
model. The incoming filament's target is raised ahead of the tool change, so the
heat-up overlaps both the change itself and the travel to the tower.
Off by default, and only offered for multi-extruder printers using a Type 2 wipe
tower; the generic toolchanger profile enables it.
* fixes: %g directive writing between 1 and 13 bytes into a region of size between 6 and 18 [-Wformat-overflow=]
* fixes: %5s directive writing between 5 and 63 bytes into a region of size 58 [-Wformat-overflow=]
* fixes: catching polymorphic type by value [-Wcatch-value=]
* fixes: [-Wcomment]; removes whitespaces
* increases buffer size from 71B to 90B to avoid potential ovfl.
* update snapmaker profiles. largely ported for Snapmaker Orca fork
* update prime volume
* set precise_outer_wall to 1
* Update per-material multi-tool ramming to the filament library
* Add per-filament overrides for toolchange retraction
* Set toolchange retraction per filament for Snapmaker U1
* set default support type to tree
* format snapmaker profiles
The tower travel took retract()'s default vertical Z hop instead of the
configured one, so the nozzle rose in place over the part and oozed
rather than departing with the travel. Pass the filament's z_hop_types
through, mapping Auto to a spiral lift as append_tcr does.
* Sync WipeTower from BambuStudio(through ca1881761)
* Fix post-slice self-invalidation on custom multi-extruder printers
* Complete the rib wipe tower port in WipeTower2
The rib tower is now always square (prime_tower_width is ignored, as the
GUI already implies), carries the rib origin offset like the BBL tower so
the rib tips sit inside the configured position, clamps the rib length to
the tower diagonal, and extends the ribs for short towers.
* Use the squared rib tower size in arrange estimates
estimate_wipe_tower_polygon reserved the arrange footprint and clamped the
tower X position with the raw prime_tower_width, under-reserving space
whenever the rib wall squares the tower to a different width.
* Print the WipeTower2 shell with a non-support, non-soluble filament
Like the BBL tower: the layer's sparse infill, wall, and brim go to the
first toolchange to a non-support/non-soluble filament, or are printed
with the incoming filament before any toolchange. The minimal-purge
clamp now also covers toolchanges that get no finish-layer saving.
Output is unchanged when no support/soluble filament is used.
* Port the skip-points gap wall to WipeTower2
prime_tower_skip_points was stubbed for Type2 towers: the wall call
hard-coded skip_points=false, the gap cutter received an empty vector,
and append_tcr2 never routed the entry travel. Now the toolchange entry
positions are precomputed from the finalized plan, the wall is cut open
at each entry, and the entry travel approaches around the tower bounding
box through the opening when it starts outside the tower. The geometry
helpers are re-synced with the BBL versions (add_extra_point guards,
per-point side selection). The cone wall keeps its separate path, where
the option stays inert.
Behavior change: non-BBL towers now honor the (default-on) checkbox with
gap walls and routed entries; with the option off the output is
unchanged, and the BBL tower path is untouched.
* Route the in-place toolchange tower entry through the skip-point gap
On multi-tool printers without ramming the tool changes away from the
tower and the entry travel is the tcr's own positioning move, which went
straight across the printed wall. Append the avoid-perimeter path to the
change-filament gcode instead, so the head approaches around the tower
and enters through the wall opening (append_tcr parity).
* Iron the purge start out through the skip-point gap in WipeTower2
Port the BBL tower's entry line ironing: extrude the first 3 mm of the
purge, retract, drag the nozzle 1.5x back out through the wall gap at
F600, creep back at F240 and unretract, so the toolchange start blob
ends up in the gap instead of on the wall. Fires only when the purge
starts at the left-edge entry heading right (in-place toolchangers);
SEMM ram/cooling wipes start mid-box and the priming line has no wall,
so both keep their previous output.
* Reserve WipeTower2 toolchange depth to match the printed purge
The planner reserved ramming rows gated only on enable_filament_ramming and
sized them with the SEMM 0.25s time step, while toolchange_Unload rams on
(semm && enable_filament_ramming) || filament_multitool_ramming with the
multitool time step. Disabling multitool ramming therefore left ~3 unprinted
rows per toolchange as blank bands in the tower. Without ramming the first
wipe line also needs reserved depth of its own (it no longer rides the last
ramming row), plus the y_step/2 offset the wipe start inherits from the
ramming start position - otherwise the tightened boxes truncate the ordered
purge at the box edge.
* Tile WipeTower2 purge rows contiguously across toolchange blocks
Without ramming, each purge block reserved one wipe pitch more than its
rows occupy (ceil+1 rounding plus the ram-geometry start offset), and the
wipe began a full pitch inside the block, leaving a blank band of exactly
two pitches between adjacent blocks. Plan the block as whole wipe rows,
start the first row so the row lattice continues across the block
boundary, and fill the reserved box instead of stopping at the ordered
volume, mirroring how the BBL WipeTower keeps planned depth identical to
printed rows. Ram-printing toolchanges (SEMM with ramming enabled,
multitool ramming) are unchanged.
* Scrub the WipeTower2 toolchange entry with the BBL flat-ironing spiral
The entry scrub now matches the BBL tower's toolchange_wipe_new sequence:
after the ironing drag the retracted nozzle runs a dry expanding-square
spiral centred on the wall-gap entry point before resuming the purge row.
The spiral runs whenever the gap wall is on (disable per filament via
filament_tower_ironing_area = 0); WipeTower2 no longer reads
prime_tower_flat_ironing.
* Restart the WipeTower2 wipe at the box boundary after multitool ramming
With the gap wall on a multi-tool printer, quantize the ram band up to its
whole reserved rows (as the BBL tower does for the old-tool purge) and start
CP TOOLCHANGE WIPE at the left-edge boundary on a fresh row below it instead
of continuing from wherever the ram serpentine ended. The entry scrub then
runs at the wall gap on ram toolchanges too, and the wipe box is whole rows,
so it is filled completely like the no-ram case. SEMM and skip-points-off
behavior is unchanged.
* Move the WipeTower2 wall gap to the wipe start row for ram toolchanges
* code cleanup
