harrierpigeon b1905ebc20 Belt brim: fixes from review
Six issues found by reviewing the previous commit against belt-printer, two of
them release-blocking.

Data race (high).  Print::process() runs generate_support_material() for all
objects in a tbb::parallel_for, and make_belt_brim() runs at its tail, but
belt_brim_obstacles() read every OTHER object's support_layers() - which a
concurrent task may be inside clear_support_layers() deleting.  That is a
use-after-free, and even when it survives, the obstacle set depends on which
object finishes first.  Only this object's own supports are consulted now; they
are complete at that point.  Foreign objects still contribute their slices,
which are finished and immutable before the support phase.

Apron bands dropped (high), two separate causes.  An apron band prints below
its own object's first layer, but another object can already be printing at
that print_z, in which case process_layer() takes the ordinary path and never
emitted the band - the emission is now shared by both paths.  Separately, a
band whose print_z matched a support layer of the SAME object was overwritten
in the print-wide merge, which keeps one record per object per z and could not
detect the collision because LayerToPrint::layer() is null for a band.  The
per-object pairing loop is now a three-way merge over object, support and apron
streams, so each object contributes at most one record per z.

Multi-instance was far too strict (medium).  It refused belt brim for every
multi-instance object, killing plain brim width and inner brim too, and only
warned when a leading length was set.  Only movement ALONG the belt changes an
instance's belt-floor Z, so copies side by side ACROSS the belt share one set of
bands perfectly well; belt_brim_instances_compatible() now tests just that, and
the warning fires whenever the brim is actually suppressed.

Apron layer bookkeeping (medium).  Apron layers count toward m_layer_count and
advance m_layer_index, but emitted no Z/height tags, left m_last_layer_z,
m_max_layer_z and m_last_height stale - so the first object layer computed its
height against a pre-apron Z - and skipped before_layer_change_gcode and
layer_change_gcode entirely.  All of that now matches the ordinary path.

Obstacle cost (low).  belt_brim_obstacles() ran a full-plate union per band.
A bounding-box pre-filter drops non-overlapping objects before materialising any
polygon, and the union is skipped for trivial inputs.

Deliberately unchanged: every apron band still reports cooling layer_id 0.
CoolingBuffer uses it for the initial_layer_fan_speed override and the
close_fan_the_first_x_layers gate, and every band lies on the belt plane itself,
so it is all first-layer material by the only definition that means anything on
a belt.  Numbering the bands would ramp the fan up while still printing on the
belt.  Now documented at the assignment rather than left implicit.

harrierpigeon 55b4dca9bc Belt printers: brim laid onto the tilted belt, with a leading apron
A belt printer slices in a rotated frame, so the belt surface is a tilted
plane rather than the Z=0 bed plane.  Each slicing layer touches the belt
only along a narrow strip at its leading edge - about 0.2mm at 45 degrees -
so a part's first layer is really a first line, with almost no contact patch
to hold it down while the belt drags it forward.  Brim was hard-disabled on
belt printers, leaving no remedy at all.

Generate the brim on the belt plane instead.  The object's belt footprint is
the union over layers of each slice clipped to that layer's contact band; the
brim is offset from it in a "flattened" frame where the shear axis is
stretched by 1/cos(tilt), so ordinary Clipper offsets measure true on-belt
distance.  It is emitted as cross-belt lines, one per layer band, anchored to
a fixed fraction of the band so every line shares a nozzle-to-belt clearance
and therefore comes out the same width; flow is matched to the resulting band
pitch, keeping the sheet uniform and gap-free.

Three new controls, all belt-only:

  * Leading brim length - extends the brim ahead of the part along the belt,
    on every downhill-facing edge of its contact area.  This apron necessarily
    prints BELOW the object's first layer, since layer 0 is the part's leading
    contact, so it needs brim-only bands of its own.
  * Extra brim width - widens the brim sideways across the belt only.
  * Brim type "Leading edge only" - brim at the part's first belt contact and
    nothing after it.  Appended last in BrimType so no existing value shifts;
    degrades to an outer brim off belt printers, with a warning.

The apron bands are lightweight records rather than a Layer subclass, so no
fabricated Layer::id() can leak into initial-layer temperature selection, the
spiral vase probe, cooling or gradual interpolation.  They are generated in
posSupportMaterial because their print_z values must exist before ToolOrdering
is built at psWipeTower, and they are emitted from a short dedicated branch in
process_layer that runs before any layer pointer is dereferenced.

The footprint is closed before offsetting outwards: a belt contact patch is
often a broken-up strip, and the merged offset rings of two islands closer
than 2 x brim_width would otherwise fill the space between them - space that
lies under the part.

Also fixes a pre-existing bug where PrintObject::get_first_layer_bbox()
overwrote a valid bbox with an unassigned one on any belt printer with a brim
configured, because has_brim() was true while make_brim() returned early.

Belt brim is refused alongside the prime tower and spiral vase, and requires
one instance per PrintObject - translating an instance along the belt axis
changes its physical belt-floor Z.  Untilted belt printers are unchanged: they
still get no brim, since the plate brim is emitted out of skirt_brim_groups(),
which _make_skirt() never builds for a belt printer.

harrierpigeon 175075fd08 Merge upstream/main into belt-printer
Brings the belt-printer work up to date with 591 upstream commits.

Conflict resolutions (12 files, 42 hunks):

- GCode.cpp: adopted upstream's per-filament/per-nozzle config refactor
  (get_filament_config_index, NOZZLE_CONFIG), the extracted
  generate_timelapse_gcode + farthest-point timelapse, and the
  ConfigOptionFloatsNullable calibration options. Re-applied the belt
  hooks on top: init_belt_writer / axis remap / FirstLayerPlane setup,
  on_set_origin, the belt-corrected calib_z for the volumetric speed
  tower, and path_on_first_layer (belt's per-path first-layer test) in
  place of upstream's layer-index on_first_layer() in the acceleration,
  jerk and overhang-detection paths. Swept upstream's new m_writer.
  uses to m_writer-> since belt holds the writer by unique_ptr.
- interpolate_value_across_layers: kept upstream's banded stepping and
  belt's object-Z-span ratio; dropped upstream's duplicate ratio decl.
- Plater.cpp: took upstream's guarded add_model(...) early-returns and
  the VFA vfa_layer_height plumbing; kept the belt temp-tower path,
  _calib_apply_belt_mode and belt_calib_flip_ringing_tower. Dropped the
  VFA "cut upper" block, superseded upstream by model scaling.
- Brim.cpp: upstream's ObjectInstanceID-keyed brimAreaMap, keeping the
  belt early-return.
- 3DScene.cpp: kept both the belt build-plate tilt up_direction and
  upstream's per-extruder printable-height shading.
- GCodeViewer.cpp: kept upstream's dim-previous-layers setup and belt's
  exemption from the same-result early return.
- TreeSupport.cpp: upstream's >= 0 roof-layer fix inside belt's
  belt-floor branch.
- calib.cpp / GCode.hpp / GCodeWriter.{cpp,hpp} / Print.hpp: upstream's
  additions adapted to belt's pointer-held writer and helpers.
- Custom.json: kept profile version 02.04.00.03 (belt) over upstream's
  02.04.00.01; both bumped from 02.04.00.00.

Building this tree needs the wxInspector dependency, which upstream
added in the interim (python3 and wxWidgets 3.3.2 were already present
in the shared deps prefix).

SoftFeverandCopilot Autofix powered by AI 6a2a57bdf4 Bring the rib wall and skip-points prime tower to all printers (#15035)
* 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

* Potential fix for pull request finding

SoftFever 582017235c feat(engine): resolve per-variant config columns for raw filament reads on the export path
When a per-layer nozzle grouping migrates a filament across nozzle
variants, the write-back turns two groups of config arrays from
filament-indexed into column-indexed: the per-variant filament options
(one column per variant a filament uses) and the merged extruder
retract overrides (resized to the column count by apply_override).
Export-path readers that still indexed them with the raw filament id
read a neighbor's column for every filament ordered after a migrating
one: toolchange/standby temperatures (M104/M109), retraction lengths
and feedrates, wipe distance, z-hop types, air-filtration keys, and -
through the Extruder's cached flow term - the extrusion E of every
move.

Now every such read resolves its column through the existing
layer-aware resolver (get_filament_config_index ->
Print::get_filament_config_indx), which returns the raw filament id
whenever no per-layer grouping result is published, so static prints
are byte-inert by construction. The Extruder itself has no layer
knowledge, so it gains an injected config column (set_config_index,
default = filament id) that the generator refreshes at the only two
resolution-changing events - layer change and writer toolchange - and
that re-syncs the cached e_per_mm3 flow term. Old-filament reads
resolve at the current layer, which is safe because the per-layer maps
are gap-filled carry-forward. Whole-array placeholder copies
(toolchange temperature overrides) are rebuilt in filament order,
mirroring the existing per-variant placeholder remap. The resolvers
move to the public section so non-friend helpers (ooze prevention) can
resolve too.

Documented, deliberately unchanged: the wipe tower's per-filament
parameter rows (no layer dimension; tower x per-layer grouping is a
follow-up), travel_slope's physical-extruder read, estimator pre-heat
bookkeeping temps, and index-0 header diagnostics.

Verification: new Extruder column-injection scenario (defaults, column
follow + flow-cache rescale, filament-indexed reads unaffected, reset
semantics) and a migrating write-back case proving the column shift for
filaments ordered after a migrator and the resolver tracking it (11 +
14 assertions); suites green (libslic3r 48998/169, fff_print 655/61);
20/20 pinned-slice byte gate bit-identical (incl. sequential repro x2
deterministic).

SoftFever 21b46044d0 feat(gcode): resolve per-filament variant slots per layer
- the g-code writer tracks the current layer id and resolves
  FILAMENT_CONFIG/NOZZLE_CONFIG (plus every non-macro variant lookup,
  toolchange placeholder scalars, and the change-filament flush
  overrides) through Print's per-filament, per-layer config-index
  resolvers instead of the filament->extruder collapse
- update_layer_related_config refreshes the per-layer
  extruder/volume/nozzle maps in the writer config;
  update_placeholder_parser_with_variant_params remaps the
  filament-variant arrays into filament-id space for custom g-code
  (Orca's flush placeholder computation moves inside it)
- the engine's concrete per-filament volume assignment now merges into
  the config write-back (the temporary hold from the producer commit
  is lifted together with these consumers), and the background process
  reads the computed volume map back to the plate
- append_full_config dumps the resolved filament_map_2 slots
- update_used_filament_values gains a bounds guard
- tests: per-filament Hybrid slot resolution + null-result fallback

Result: on a Hybrid extruder, each filament's features slice with its
assigned sub-nozzle's variant values (speeds, volumetric limits,
retraction). Verified on a 4-filament H2C Hybrid project: outer walls
split into three feedrate populations (30/50/200 mm/s), toolpath
geometry byte-identical, deterministic across repeated slices. All 18
non-Hybrid reference fixtures stay byte-identical except the
filament_map_2 header value now showing the real slot. Auto grouping
ties (multiple zero-flush perfect matchings) may pick a different
filament-to-nozzle isolation than other slicers; verified co-optimal.

Kiss LorandandSoftFever 045179150f Refactor skirt/brim + bugfixes related to them (#14333)
Refactor skirt and brim ownership and emission flow

Refactor skirt and brim generation around a common object/group
ownership model.

Skirts and brims are now emitted as a coordinated preamble
(skirt -> brim -> object) instead of being generated and emitted
through multiple independent code paths.

Changes:
- Fix repeated skirt emission caused by the previous skirt state
  tracking logic.
- Restore local skirt/brim ordering for per-object skirts in
  By Layer mode.
- Emit brims together with their owning object or object group.
- Handle combined brims independently from skirt grouping.
- Handle draft shields through the same ownership model as skirts.
- Fix draft shield generation when skirt height is zero.
- Generate draft shields after brim geometry is known, preventing
  draft shields from overlapping brims.
- Reject unsafe grouped per-object skirt configurations in
  By Object mode.
- Remove legacy skirt emission paths and state-management
  workarounds.

Support brim generation remains unchanged.

GCode.cpp: combined upstream's air-filtration per-extruder gating
(activate_air_filtration_during_print / _on_completion), the new
extrusion-role-change gcode lambda, ZAA's path.z_contoured arc-fit
disable, raft-aware slow_down_layers branch, and Vec3d/Line3 ZAA
plumbing with the local belt-printer changes (path_on_first_layer,
effective_layer_index_for_point, should_disable_arc_fitting). All
auto-merged m_writer.X() calls converted to m_writer->X() to match
the local unique_ptr<GCodeWriter> refactor.

GUI_Factories.cpp: inserted brim_flow_ratio in the Support category
list and renumbered around the local build_plate_tilt_x/y entries.

Previously, wipe tower behavior was determined by checking if the printer

SoftFever c085eb845c Fix machine envelope G-code emitting wrong limits due to broken extruder_id indexing (#12414)
print_machine_envelope() used get_extruder_id(extruder_id)*2 to index
machine limit arrays that only hold [Normal, Stealth] (2 entries).
For multi-extruder setups this went out-of-bounds, causing wrong M201/M203
values in the G-code which then override the estimator's correct limits.

Same class of bug as c6d1c11ebb but on the G-code writer side.

Changes:
- Remove unused extruder_id param from print_machine_envelope()
- Use .values.front() for M201/M203, matching M204/M205 in same function
- Change get_option_value() fallback from .back() to .front() so any
  future out-of-bounds index returns Normal mode instead of Stealth

Matthias Nott 963f8d86b7 feat: Add Z Anti-Aliasing (ZAA) contouring support
Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.

Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
