ExPikaPaka 7766c2e003 Test that a baked texture still slices
The bake is covered in the libslic3r suite, but nothing carried its
result through the slicer - where a mesh it cannot use shows up as a
crash or as a print with no toolpaths, which is what was reported on
macOS and Linux.

Paints a cube, bakes it as the gizmo commits it (mesh replaced, hull
recomputed, paint cleared), slices it and checks the G-code has
toolpaths and layers. Once under its budget and once capped, since a
capped bake also goes through the simplification and the repair.

SoftFever da951ad7f3 Load profile includes so synced Bambu Lab presets get their G-code back (#15869)
# Description

This brings back the Bambu Lab profile sync with BambuStudio, reverted
from main, along with its bed-model offset fix. The synced printers and
filaments share their start and end G-code and dual-nozzle settings
through template files that Orca did not read, so those printers had no
machine G-code. Orca now loads these templates the same way BambuStudio
does, so every synced preset comes in complete. `profile_include_dump`,
a new developer tool, compares the result with BambuStudio's.

Other vendors' profiles are unaffected. Bambu Lab profiles move to
version 02.08.00.10, so installs that took the earlier sync update too.

## Tests

Unit tests cover how template settings combine with inherited and preset
settings, loaded from JSON and from the preset cache. The profile
validator passes on every shipped vendor, and every Bambu Lab preset
gets the same template values in Orca as in BambuStudio.

HanifKoh db10c719f6 Keep the Scarf Seam Free of Sub-Millimetre Segments (#15832)
A scarf joint split the loop at exactly the scarf length, so the remainder
of the segment the split landed in became the first flat segment, often a
fraction of a millimetre. The seam insertion also leaves segments of a few
micrometres at both ends of the loop, which a scarf extrudes through where a
plain loop would start or stop. With junction deviation the planner treats
such short moves as tight corners, limited by the Z axis acceleration at the
end of the ramp, and slows to a third of the wall speed or nearly halts at
the seam.

Extend the ramp to the next vertex when the remainder would be shorter than
half a scarf step, capped at a millimetre, beyond which planners treat a move
as ordinary; the scarf only grows, never shrinks. Drop the vertex next to the
seam point at either end when that segment is shorter than an eighth of a
common line width, so the loop still starts and ends at the seam; a trimmed
path loses its arc fitting and prints as line segments. Clamp the scarf
length to the trimmed loop so a scarf covering a whole loop still ends at
full flow. The descending pass reuses the same path, so both wedges stay
consistent, and a flat part that would collapse to a single point is dropped.

HanifKoh af52da061f Report Per-Object Slicing Errors in the CLI (#15834)
G-code generation collects errors raised per object, such as an empty
first layer, into one SlicingErrors exception whose own message is just
"Errors". The CLI's generic handler printed that word and recorded the
generic slicing error text, so a headless caller had nothing to act on.

Let Print render the per-object messages with each object's name, and have
the CLI catch SlicingErrors ahead of the generic handler, print that text
and record it as the result's error string. The exit code is unchanged. A
unit test lifts a cube off the bed and checks the message names the object.

Clifford GarwoodandClaude Opus 5 84c13d4913 Merge upstream main: wipe tower port, per-filament bounds checks, CLI mixed rules
Four files overlapped, and each resolution favours upstream where the two sides
had done the same work:

WipeTower's M104/M109 tool qualifier. Both sides bounds-checked the physical
extruder map lookup; upstream omits the T qualifier when the map cannot answer,
where this branch fell back to the logical index and so named a carriage that may
not be the one printing. Upstream's behaviour is what this branch documents
elsewhere, so its version is taken and the local helper is dropped.

get_extruders' mixed-slot switch. Upstream added the same concept to the CLI
overload as expand_mixed_slots, so the GUI overloads' parameter is renamed to
match rather than carrying two names for one idea.

GLCanvas3D's sequential-clearance branch gains upstream's
update_compacted_wipe_tower_clearance for the by-layer case.

The printer_agent re-sync in TabPrinter::reload_config was upstream's and their
preset-undo fix removed it, so it goes; the IMEX modes grid re-sync beside it
stays, since it spans three options and is not a Field.

packerlschupfer 9321f24959 CLI: --strict, and a warnings array in result.json (#14601)
# Description

Add `--strict` for CI and scripted pipelines, and a structured
`warnings`
array in `result.json`.

## `--strict`

A NON_CRITICAL slicing warning is logged and the slice succeeds: return
code
`0`, G-code written. That suits interactive use, but a pipeline then
ships a
slice with a warning nobody saw. With `--strict`, such a warning fails
the run
with `CLI_SLICING_ERROR` before the G-code is exported. Without the
flag,
nothing changes.

In FFF the warning that reaches this path is "support needed but
disabled"
(`PrintObject::generate_support_material`). `--no-check` skips that
check, so
`--strict --no-check` is rejected with `CLI_INVALID_PARAMS`.

`--strict` is read before any work, so it doesn't depend on argument
order and
`result.json` reports it for early failures as well.

## `result.json`

Two new top-level fields:

- `warnings`: `[{"class", ...details}]`. One class is wired:
`slicing_warning_non_critical` with `plate_id` and `text`, recorded
whenever
such a warning fires, with or without `--strict`. The array also fills
on
  runs that succeed, so `return_code` stays the verdict.
- `strict_mode`: whether `--strict` was on.

`record_exit_reson` writes `result.json` on Linux only, so both fields
exist
only there. The non-zero exit works on every platform.

## Tests

- `tests/fff_print/test_support_material.cpp` (all platforms): an
overhang
sliced with support off raises the NON_CRITICAL support-needed status,
and
  the no-check flag suppresses it.
- `tests/cli/test_cli_strict.sh` (Linux only): runs `orca-slicer`
without
flags, with `--strict`, and with `--strict --no-check`, and checks the
shell
status and `result.json` of each. It runs the built binary, so it
carries the
`RequiresApp` label, which `scripts/run_unit_tests.sh` excludes because
the
  unit-test job only receives `build/tests`. Run it with
  `ctest --test-dir build/tests -C Release -L RequiresApp`.
- CI: `unit_tests.yml` now passes `Release` on Linux too.
`build_linux.sh`
configures Ninja Multi-Config, and without a config ctest drops the
labels of
plain `add_test()` tests, so this test ran as "Not Run" instead of being
excluded. The docs that assumed Linux was single-config are corrected
too.

Built and run locally on Linux (GCC 14) on current `main`: both tests
pass,
and the touched files compile clean under Clang with `-Werror`.

Daniel Williams 70247ad298 Extract Layer::choose_ironing_extruder for unit-testable ironing routing (#13467)
* Extract Layer::choose_ironing_extruder for unit-testable ironing routing

The ironing extruder selection in make_ironing() was a 5-line nested
conditional inlined at the top of the loop, with no isolated test
coverage. Pull the gating into a static helper so the routing decision
is unit-testable without spinning up the slicing pipeline.

Pure refactor: the helper preserves the original logic bit-for-bit
(NoIroning -> -1; AllSolid always enabled; TopSurfaces and TopmostOnly
require some top shells or, in spiral mode, more than one bottom shell;
TopmostOnly additionally requires being on the topmost layer; enabled
ironing routes to solid_infill_filament).

Add tests/fff_print/test_choose_ironing_extruder.cpp covering:
- AllSolid regardless of layer position
- TopSurfaces with top_shell_layers > 0
- TopSurfaces with top_shell_layers=0 + spiral mode + bottom_shell_layers>1
- TopmostOnly + topmost layer
- NoIroning short-circuit
- TopSurfaces with top_shell_layers=0 (and not spiral) -> disabled
- TopSurfaces, spiral, but bottom_shell_layers=1 -> disabled
- TopmostOnly on a non-topmost layer -> disabled

* Move ironing routing test into the Fill subsystem file

Rename the test to tests/libslic3r/test_fill.cpp and tag it [Fill] to
match the subsystem it covers, use flat behavioral test cases with
GENERATE for the parameterized ones, and drop the history narration from
the code comments.

* tests: move ironing routing tests into fff_print/test_fill.cpp

Keeps the Fill tests in one file, alongside the existing ironing
rotation-template test.

Hanif Koh f2a11928f6 Read the Belt Tilt Only from the Belt G-code Header
Every printer's config block lists belt_slice_rotation_angle (default 45), so the processor marked all G-code as belt G-code: imported flat G-code got the belt view on a belt printer, and the belt-only Z handling in the processor ran for non-belt prints whose config block precedes the body. Take the angle only from outside the config block, where only the belt header writes it.

Conflicts resolved:
- src/CMakeLists.txt: keep both wxInspector workarounds.
- GCodeProcessor.cpp: keep the belt compare_pos / z_for_height lines.
- PrintObjectSlice.cpp: the belt bbox-Z guard also covers main's
  printable_region_ids bookkeeping.
- TreeSupport.cpp: the belt-floor check runs before main's PendingNode
  queueing.
- Tab.hpp: keep the belt fields, drop the removed upload description
  fields.
- tests/libslic3r/CMakeLists.txt: keep both test files.

Also included:
- eSUN PLA belt presets declare their own filament_id (OFkrxQC4) and
  scripts/filament_id_snapshot.json is regenerated, as main's filament_id
  check requires.
- Custom.json version bumped to 02.04.00.05 so the belt entries reach
  existing installs.
- Fix the ambiguous WithinRel call in the belt apron width test, which
  otherwise breaks the fff_print build.

Valerii Bokhan e8d35fadd4 Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill (#15206)
* Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill

For patterns with curved/turning anchor lines (Hilbert Curve, Octagram
Spiral), the bridge_over_infill algorithm produced incorrect results:

1. determine_bridging_angle: sampling curved anchor orientations
   produced noise across all turning directions (0/90/180/270°)
   instead of a single dominant one, yielding unstable bridge angles
   with 180° spread. Fix: use the configured infill_direction + 90°
   directly, bypassing the noisy sampling. The old blind +0.25*PI
   (Hilbert) and +1/16*PI (Octagram) offsets are removed.

2. construct_anchored_polygon: curved Hilbert/Octagram anchors
   intersected each vertical scan line many times at wildly different
   Y positions, producing chaotic polygon sections — holes in random
   places, bridges over air, rotated bridges. Fix: replace the curved
   infill polylines with synthetic straight lines parallel to
   infill_direction, spaced at the real infill line spacing
   (flow_spacing / density). Lines are centered on the limiting_area
   bbox center so that after rotation they span the full bridged_area.
   Anchors are left at full bbox length (not clipped) to guarantee
   every scan line finds an anchor.

Rectilinear and other straight-line patterns are unaffected.

Known limitation: some bridge edges may still terminate over air in
edge cases where the nearest synthetic anchor line is more than one
infill spacing away from the bridge boundary. This will be addressed
in a follow-up.

* fix: anchor internal bridges to actual sparse infill

Preserve real anchors across regions and align plane-path anchor origins with printed infill. Respect lower-layer rotation templates and model alignment, and sample curved bridge boundaries more finely.

Add regression coverage for anchor alignment, bridge angles and region isolation, with Orca comments explaining the geometry constraints. Verified 175 FFF tests before the comment-only follow-up; preserve CRLF in modified files.

* Fix internal bridge support contacts and separated infill origins

Restore anchor contact after bridge smoothing and share per-body pattern origins between anchors and printed infill. Recompute origins when preparation settings change.

Cover multiline counts 1, 2 and 3 and add regressions for printed bridge support, separated infill alignment and reslicing.

* Add explicit standard headers to PrintObject tests

* test: cover surface centering when infill settings change

Verify top and bottom Archimedean Chords and Octagram Spiral paths after switching centering modes or toggling separated infills. Compare reslicing against fresh slicing and document dependent infill invalidation.

* test: preserve directional surface infill when settings change

* perf: index layer islands for connected-body detection

* test: use public print pipeline for body centering checks

Hanif Koh 81357695c5 Verify WipeTower Footprint at Point of Generation
The clamps and validation work from estimates. Once the tower is
generated, _make_wipe_tower re-tests the exact first-layer footprint,
brim and cone base included, against the printable area and the
exclusion zone, so an off-plate tower fails with a clear error instead
of exporting unprintable G-code. The rectangle-wall mesh footprint
learns the Type2 cone base so that check and the post-generation
validation see the real outline.

Pre-generation, validation hard-checks the body plus an explicit brim
and warns on the estimated auto brim and cone base with the existing
"may collide" strings, so the user hears about a marginal position on
the first slice rather than only at generation time.

Two fff_print fixtures that print a tower at the default position move
it onto the 200 mm test bed, as the multifilament fixtures already do:
the shipped default y of 220 is off that bed, and the backstop now says
so instead of exporting the tower.

Hanif Koh 99627c8e93 Size the Footprint Estimate from the Planners
The shared estimate reserved every tower with one volume-per-purge rule
and the stability floor. Both planners do more: WipeTower (Type1) wipes
each filament's own prime volume in whole lines, one block per
adhesiveness category sized by its worst layer, rams the leaving
filament at every nozzle change, and squares a rib tower from the
planned depth; WipeTower2 (Type2) spaces its lines by
wipe_tower_extra_spacing, not the Type1-only infill gap, and its extra
flow cancels out of the depth. Both extend the ribs rather than the body
below the stability minimum, size every layer including a thinner first
one, and lay the brim in whole loops, WipeTower reporting half a spacing
of line width on top.

All of that now lives in estimate_wipe_tower_footprint, fed the planner
(resolve_wipe_tower_type mirrors Print::wipe_tower_type and the CLI's
Bambu Lab detection) and the filament ids rather than a count. Print
passes its own tool set; the PartPlate adapter derives the plate's ids
from the passed config and treats an explicit count as a floor, so the
CLI's count-only callers size per filament too. The placement clamp also
reserves a Type2 cone's base bulge, which the body box does not cover.

The planner-mirroring helpers sit beside the planners in WipeTower and
WipeTower2 so the two stay in sync; the libslic3r cases pin them to
footprints measured from generated G-code.
2026-09-09 15:45:16 +08:00
Hanif Koh e1efec7d6c Fix review findings in the shared wipe tower estimate
A raft is not a reason to reserve a tower. Print::apply runs
normalize_fdm_2, which clears enable_prime_tower for a plate that purges
one filament unless smooth timelapse or wrapping detection is on, so a
single-filament plate with a raft prints no tower at all and the estimate
was reserving bed area for one. Drop the input; need_wipe_tower is now
exactly the two exceptions normalize_fdm_2 honours, named there so the
next reason added has to be checked against it.

The GUI preview and the validation containment check each re-derived
"is a tower printed here" from the filament count instead of reading the
estimate, so both missed the towers printed with no tool change to purge
for. They now take the answer from the footprint, which is the drift this
shared estimate exists to remove. A tower that is not printed estimates to
zero, so its hull is degenerate and every check on it passes trivially -
the containment check needs no gate of its own.

WipeTowerData::width was written only by the pre-generation estimate and
left at zero for the whole post-generation life of the Print, while its
neighbour depth held the real value. Set it from the generator in both
branches.

The plate's height scan transformed every model part's full mesh per
instance on each scene reload, discarding all but the z extent. The
cached convex hull has the same z extent.

A plate loaded from a sliced .gcode.3mf holds no objects and its filaments
live in slice_filaments_info; the config-taking get_extruders overload
returned an empty list for it, which sized the tower for a placeholder two
filaments. It now answers the way the wx overload does, without reaching
the plater.

Also drop estimate_wipe_tower_size, which has no callers.

harrierpigeonandClaude Opus 5 4d2c3a0af4 GCodeWriter: fix two machine-mapping bugs the extraction preserved
Both change emitted G-code, which is why they were kept out of the extraction
commit. Both are wrong only where the machine mapping is non-identity, which is
the definition of each bug.

1. Suppress lifts commanded through an unknown position.

_travel_to_z() emits full XYZ whenever the mapping must emit every axis, because
the mapping can make machine Z depend on logical X/Y, and it builds that point
from m_pos. At print start, and after any custom G-code that invalidates
position, m_pos.xy is the uninitialised origin; mapping (0, 0, z) through a
non-identity remap produces a real but wrong machine point -- for a reverse
mapping, build_vol_max, i.e. the far corner of the bed. The subsequent full-XYZ
move corrects the position, but the lift has already commanded a rapid across
the whole bed at travel speed.

Belt kinematics already guarded this; the Cartesian path did not. The guard is
now applied at all three lift sites through must_skip_lift_now(), not just the
one the extraction covered: travel_to_xyz()'s pending-lift branch,
lazy_lift(spiral_vase=true), and eager_lift(). The latter two also needed the
state fix -- both recorded m_lifted = target_lift regardless, so suppressing
only the emission would leave a later unlift() descending from a height that was
never commanded.

2. Never emit a G2/G3 arc a mapping cannot represent.

extrude_arc_to_xy() emitted G2/G3 with logical X/Y and I/J and never consulted
the mapping. There is no general fix by transforming the arc: a permutation
moves it out of the XY plane that I/J describes, a negation reverses handedness,
and the belt shear maps a circle to an ellipse that G2/G3 cannot express at all.

So supports_arc_moves() gates generation through the existing
GCode::should_disable_arc_fitting() hook, and BeltGCode's special-case override
is deleted -- belt now gets the same behaviour from the general rule instead of
its own exception.

supports_arc_moves() is m_remap_x == 0 && m_remap_y == 1, not !has_axis_remap():
an arc emits only X/Y/I/J, so a mapping that merely negates or reverses Z leaves
every emitted word untouched and keeps its arcs.

The fallback for an unrepresentable arc tessellates it into linear segments at a
0.005mm chord tolerance rather than substituting a single chord, and splits dE
proportionally across the segments. The capability check is hoisted above every
extrusion mutation: an earlier form ran it after filament()->extrude(dE) and so
extruded 2*dE on the fallback path.

Known limits of that fallback, since it is worth stating rather than discovering:
emitted relative E is conserved only to per-segment rounding (a radius-5
semicircle with dE=1.5 emits 1.50012 across 36 segments); the 0.005mm bound is a
logical-frame bound, about 0.00855mm in machine space under a 45-degree belt
shear; unequal endpoint radii and non-finite inputs are unchecked. Ordinary
export takes the original polyline when the mapping rejects arcs, so this path
is a fallback rather than the normal route.

Known gap, not claimed fixed: classic wipe towers have their own
enable_arc_fitting and their own G2/G3 emitter in GCode/WipeTower.cpp, which
should_disable_arc_fitting() does not govern. Belt printers are barred from
classic wipe towers; a remapped Cartesian printer is not.

Tests in tests/fff_print/test_gcodewriter.cpp: reverse-X remap with unknown and
with known position plus an identity control; eager_lift emitting nothing and
recording nothing; the arc-capability matrix including the Z-only cases; and the
tessellated fallback. E accounting is asserted through used_filament() rather
than E(), which resets per line in relative-E mode.

harrierpigeonandClaude Opus 5 e695da66df GCodeWriter: extract MachineKinematics, delete BeltGCodeWriter
BeltGCodeWriter subclassed GCodeWriter and overrode seven methods, five of them
by copying the base body and changing the transform. The base writer already
carried an axis remap and already branched at each of its seven
coordinate-emission decisions; the subclass did the same branching with a
different transform, and the two copies had begun to drift.

Replace the inheritance with a strategy object owned by GCodeWriter:

  CartesianKinematics  to_machine = the existing apply_axis_remap; today's base
                       behaviour, moved rather than changed.
  BeltKinematics       to_machine = MachineFrameTransform o axis_remap o
                       BeltBackTransform, plus a world_coordinates variant for
                       the PA calibration generators.

New: src/libslic3r/GCode/MachineKinematics.{hpp,cpp}, GCode/BeltKinematics.{hpp,cpp}
Deleted: src/libslic3r/BeltGCodeWriter.{hpp,cpp} (341 lines)

Points worth a reviewer's attention:

  * The predicate is must_emit_all_axes(), not couples_axes(). The base returns
    true for any non-identity remap, including pure permutations that do not
    physically couple axes, so the question is "must every axis word be
    emitted", not a statement about kinematics.
  * Every per-site word-omission branch is preserved. The base deliberately
    emits X/Y only, or Z only, or drops Z when its quantised value is unchanged.
    The strategy changes which transform applies, never whether words are
    omitted.
  * set_kinematics() replays the configured remap and build volume onto a newly
    installed strategy, because BeltGCode::init_belt_writer runs before
    GCode.cpp calls set_axis_remap/set_build_volume_max.
  * uses_pointwise_travel_speed() preserves a pre-existing divergence rather
    than introducing one: the base travel_to_xyz emits the raw configured travel
    speed in its final branch, ignoring the first-layer value computed at the
    top, whereas the belt path used the first-layer-aware value throughout. Both
    are kept. Unifying them changes feedrates and belongs in its own change.
  * The [BELT-DEBUG] block is deleted; it rate-limited itself with a
    function-local static thread_local in the hot emission path, and this is the
    commit that would otherwise have moved it into shared code.

This commit is intended to preserve existing export output. That is reviewed by
construction -- each emission site keeps its own omission branch and each policy
divergence is preserved -- and is NOT verified against a G-code diff corpus.
Building that corpus is the outstanding work here.

Two API-equivalence exceptions, neither reachable by any caller today:

  * Belt kinematics with no plane pointer installed, m_is_first_layer true,
    initial and normal travel speeds differing, travel_to_xyz() reaching its
    final branch: the old belt writer selected the initial-layer speed, the new
    writer selects the normal travel speed. The pending-lift and XY-only
    branches keep their previous selection.
  * Belt kinematics installed without set_force_normal_lift(true) and a
    non-normal lift requested: the old belt writer forced a normal lift, the new
    writer can take the slope branch.

The PA-pattern generator reaches the writer through explicit travel_to_z() /
travel_to_xy(), not travel_to_xyz() or the lazy/eager lift paths, and normal
belt export installs both the plane and the forced-normal-lift policy, so
neither exception changes output produced today. They are recorded because a
future caller could reach them.

tests/fff_print/test_gcodewriter.cpp was also not compiling before this branch:
it called writer.to_machine_coords(), a method that existed only on
BeltGCodeWriter. It never surfaced because the build targets OrcaSlicer, not
all, and BUILD_TESTS defaults to OFF, so that translation unit was outside every
compile path. Fixed here; the existing 30-degree coordinate assertions are kept
verbatim as the best available regression net.

The MST unit tests here cover the tie-break, but the drop_nodes rework

slices five configs twice each and compares the support point sequence,
which is what the node ordering moves. The MST tie one pins the branch
diameter and line width that carry Prim's equal-distance ties into the
toolpaths.

slice_with_tree_support takes an optional config list so the second case
can add the tree parameters it needs, and the double-slice comparison is
shared rather than written twice.

Both fail on main without this PR. The first passes from 60d1ceb580, the
second from e148865dd6.

Clifford GarwoodandClaude Opus 5 5eac300d91 Use IDEX/IQEX in the user-facing strings
Closes review comment 10.

`461c69c83e` settled this in April — IMEX internally, IDEX/IQEX as the user-facing label — but the
UI strings were never converted. Every translated string naming the feature now reads IDEX/IQEX:
41 occurrences across the printer and process option labels and tooltips, the modes editor, the
plate mode indicator, the pre-slice warnings, the placement refusals and the slicing errors. The
reviewer listed eight; the rest were in the same class.

Nothing else moves. The config keys keep the `imex_` spelling — `is_imex`, `imex_mode_names`,
`imex_parallel_mode` and the rest are on-disk format in existing printer presets and 3MF projects,
so renaming them would break every profile and project already saved. C++ identifiers, filenames,
comments and test names keep IMEX as well: it stays the internal name of the subsystem, which is
what covers the topology space (one gantry with 2-4 tools, 2x1 and 2x2 grids) that neither acronym
names on its own. Where a tooltip quotes a key, the key spelling is preserved and only the feature
word around it changed.

The `is_imex` tooltip is reworded rather than substituted: it already named the hardware families
parenthetically, so a literal replacement would have said IDEX/IQEX twice in one sentence.

No translation impact — no IMEX string had reached OrcaSlicer.pot or any catalogue, so there is
nothing to migrate. One test asserted on the old error text and now matches the new one.

Clifford GarwoodandClaude Opus 5 bd8dfd6250 Cover the IMEX slice offset, the mode G-code placeholders, and the non-IMEX heater guard
Closes review comments 13, 14 and 15, and adds the test for a shipped-profile
regression that nothing guarded.

- 14 and 15: compute_imex_slice_offset had eight tests on the calculation and none
  on the result, which is the whole firmware-managed path. test_imex_slice_offset
  now covers the derivation end (which config produces a non-zero offset, and that
  it is plate-local rather than moving with the plate origin -- the bug that
  shifted every plate after the first) and the consumption end (emitted
  coordinates and first_layer_print_min/max both move by the derived amount).
  The first_layer case also cross-checks the two consumers against each other: the
  declared bounds must keep the same relationship to the emitted toolpaths in both
  frames, which fails if exactly one of them is shifted. It deliberately does not
  pin the size of that gap -- it is 2.225 mm here, set by the wall generator, the
  same with no offset at all, and pinning it would fail on an unrelated change.
- 13: nothing exercised the imex_mode / imex_mode_index / imex_mode_gcode
  placeholders or the {global} flow into machine_start_gcode that their ordering
  exists to guarantee. Seven cases now do, including the ordering itself -- the
  mode script declares a global and machine_start_gcode reads it back, so moving
  the mode processing later leaves the variable undefined and fails the export --
  plus the inert cases (Primary mode, and a printer with the table filled in but
  is_imex off). All matching is whole-line, because the config block the exporter
  appends repeats machine_start_gcode verbatim and would make substring checks
  meaningless.
- New: GCodeWriter passes this->config.is_imex.value into the heater remap, and
  nothing tested that it passes the flag rather than a constant. Hardcode true
  there and the whole suite stays green while fdm_bbl_3dp_002_common, which ships
  physical_extruder_map [1,0], starts sending filament 0's M104/M109 to heater 1.
  The new case runs a two-nozzle non-IMEX printer with that map and asserts each
  filament's temperature reaches only its own tool. It uses idle_temperature via
  ooze prevention rather than nozzle_temperature: keys in
  filament_options_with_variant are re-indexed per filament by variant slot at
  apply time, and this harness pins nozzle_diameter to one value, so every filament
  resolves to the same slot and the temperatures stop telling the heads apart.

Also fixes two weaknesses in tests added earlier in this branch: an assertion that
would have been prefix-satisfied by the very routing it was meant to exclude, and
a whole-file command comparison between two slices, which this slicer's output is
not stable enough to support.

Clifford GarwoodandClaude Opus 5 5629dd29e9 Restore the pre-IMEX pressure advance output for non-IMEX printers
Closes review comment 6.

The per-tool pressure advance work changed set_pressure_advance() for users who
are not using the feature. RepRapFirmware lost its D qualifier when no tool index
was supplied: upstream emits M572 D0 S<pa> unconditionally, and a bare M572
applies to whatever tool is currently selected and errors when there is none, so
PA started depending on tool-selection state for every RRF user. The D is back,
defaulting to 0, and D<tool> is reached only from the IMEX paths.

The same rewrite had also changed the comment separator from "<value>; Override"
to "<value> ; Override" on the Klipper, RRF, Marlin 2.x and Marlin Legacy
branches, so every non-IMEX print of those flavors carried a one-byte diff.
Restored. Upstream is internally inconsistent here -- BBL and Repetier do use the
spaced form -- and the point is to match it exactly rather than to tidy it.

Emitted output for all six flavors with no tool index is now byte-identical to
upstream. Verified on a real slice: a Klipper profile emits
"SET_PRESSURE_ADVANCE ADVANCE=0.02; Override pressure advance value", an exact
string match, with no EXTRUDER= qualifier. The tests were pinning the regressed
form and are inverted.

Also records at the imex key registrations why they are kept out of the g-code
config block, matching the house convention at the other banned keys.

Clifford GarwoodandClaude Opus 5 018091f43b fix(imex): let the mixed-filament refusal outrank the multi-color rule
A mixed filament is unsupported in a parallel mode outright, but the rule saying
so ran third. A plate carrying a blend plus any second filament tripped the
multi-color rule's used > 1 gate first and was told its active tools all sit on
one gantry -- a diagnosis of a multi-color print the user never configured,
whose remedy is to go rework the mode's tool roster. The blend was never
mentioned. Move the check ahead of both rules below it; being unsupported
regardless of routing or topology, it dominates them.

Nothing is masked that leads anywhere else: every branch of
imex_multicolor_block_reason is itself confined to non-primary modes, so the
mixed message's remedy -- switch this plate to Primary -- silences those too.

Say "Mixed filaments", not "Blended". Every other string in the app calls these
mixed, including the button that creates one and the sibling refusal for the
wipe tower filament, so the user had no way to connect the message to the
feature it names.

Three comments in the block were wrong, and two of them were newly wrong. The
routing rule's bounds-check note still said "Blended slots are out of range by
construction, but they never reach here -- the rule above returns first": the
rule above is now the multi-color one, which does not return first for a single
mixed filament, and out-of-range is not guaranteed at all. Mixed slots are kept
at the tail of the filament arrays by convention, not by enforcement --
PresetBundle::set_num_filaments grows filament_is_mixed with resize(), so
raising a printer's extruder count with a blend present lands physical slots
after the mixed one. The scan is position-agnostic and stays correct; only the
stated reason was wrong.

The same discovery makes the empty-routed_list guard live rather than the dead
code it was described as. Print::apply() normalises physical_extruder_map before
validate() runs, so an unauthored map is never the cause -- but a printer with
more filaments than logical extruders leaves the tail slots outside the map, and
raising the extruder count does exactly that.

The new test validates the plate twice. The first pass, with no blend, asserts
the multi-color rule is armed at all; without it the second proves nothing,
because the rule only fires here thanks to a degenerate fixture mode whose two
tools share a gantry. Give that mode a Span tool and the whole test would pass
under either ordering while appearing to guard it. It also pins err.object,
which the mixed path sets and the multi-color path leaves null -- a discriminator
that survives the next wording change. Verified by reverting the order: the test
fails on both the message and the object.

Clifford GarwoodandClaude Opus 5 2e883df7d9 fix(imex): name the physical head in M104/M109 tool indices
M104/M109 address a heater, but every caller of the instance
GCodeWriter::set_temperature overload addresses filaments by logical id, so on a
printer whose physical_extruder_map is not the identity the emitted T named the
wrong head -- or, where the logical id exceeds the head count, no head at all.
With a map of 0,0,0,0,1,2,3 a toolchange to filament 5 emitted "M109 S265 T4"
and "M104 S190 T4 ;cooldown" while the head it meant was T1.

Upstream already treats these commands as physical: the preheat it injects in
GCodeProcessor maps through the same map before emitting, and BBS's own wipe
tower does likewise. Emitting logical is the half that never got the memo.

That mismatch also disabled the cooldown suppression beside the preheat, which
compares the line's T against pem[tool_number] and so never matched a logical
one -- 171 cooldowns survived in a two-head print where none should have. Worse,
it could match the wrong line: a cooldown for filament 1 emitted T1, and a
toolchange to filament 5 gives pem[4] == 1, so a legitimate cooldown for head 0
was deleted because the incoming head happened to be numbered 1.

Translate once, in the instance overload every logical-space caller passes
through. The static overload is already physical-in and is left alone.

Gated on is_imex. physical_extruder_map carries two readings in this tree: the
BBS paths index it by extruder id, the IMEX paths by filament id, and the two
coincide only when the filament and nozzle counts match. Mapping unconditionally
would impose the IMEX reading on profiles that mean the other one --
fdm_bbl_3dp_002_common ships a non-identity [1,0], spared today only because
single_extruder_multi_material suppresses the T qualifier entirely.

The wipe tower's interface-temperature pass has to move with it. It strips the
M109 that post_toolchange emits by searching for that filament's tool index, so
it now searches for the mapped one; left alone it would have stopped matching,
and the surviving blocking M109 would have silently defeated the interface
temperature. Its sibling pass reads WipeTower2 output, which emits no T at all,
and is deliberately unchanged.

The bare T<n> toolchange stays logical -- it selects an AFC lane, not a heater.

Test slices two objects across a head boundary, the only case that reaches this
emission: the same-physical short-circuit in set_extruder suppresses the
cooldown entirely for lane swaps within one head. It scans every M104/M109
rather than matching fixed strings, so it catches any unmapped emission and not
just the two sites changed here. With the mapping neutered it reports 101
offending lines; with it in place, none.

Clifford GarwoodandClaude Opus 5 f0778ef5fa fix(imex): shorten the off-primary message and block blended filaments
The routing error ran to roughly 450 characters and explained the mechanism
before it got to the remedy. It also offered to "edit the mode in Printer
Settings so its Primary tool is one of %3%", which on a plate whose filaments
resolve to no head at all rendered as "one of no configured extruder". Cut it
to the mode, the tool it prints with, where the plate's filaments actually are,
and the two things the user can do about it.

The second msgid that named candidate modes went with it. It could only suggest
a mode whose primary is among the routed heads, and every mode on the printers
this fires for declares 0:P, so it had nothing to offer.

Blended filaments now return before that check rather than falling through it.
A blend is mixed at the nozzle by its component toolheads, and a parallel mode
is already using those toolheads to print copies or mirrors, so the two cannot
run at once regardless of where the components route -- including when a
component sits on the declared primary. Reaching the routing rule would also
have described them wrongly: mixed slots sit past the end of
physical_extruder_map, so they resolve to no head and read as merely unrouted.

Keeps the empty-list guard the shortening first dropped. validate() reads the
raw physical_extruder_map, whose registered default is a single entry, so a
profile that declares IMEX modes without authoring a map leaves every slot past
the first outside it -- and the sentence ended in a dangling "on .".

Clifford GarwoodandClaude Opus 5 b24733cea8 Merge the color mixing subsystem into the IMEX work
Brings the upstream color-mixing feature and its follow-ups onto the branch so the
IMEX placement and primary-routing checks are built and tested against them for the
first time.

Merged clean, no conflicts. Not yet exercised together: a mixed filament is a virtual
slot no nozzle carries, while physical_extruder_map routes logical slots to physical
heads, so the IMEX pem lookups have no defined answer for one. Print::extruders()
lists mixed slots under their own id while tool_ordering.all_extruders() lists them
post-expansion, and the IMEX code reads both.

Clifford GarwoodandClaude Opus 5 ba07716ddb Merge upstream main: color mixing feature and related fixes
Brings in 54 upstream commits, the bulk of them the BambuStudio-ported color
mixing / mixed filament subsystem (#15347) plus its follow-ups, along with the
Assimp-backed colored OBJ import, warning-policy build changes, and assorted
profile and localization updates.

Two conflicts, both "each side added at the same point", resolved by keeping
both:

- Print::validate() -- our IMEX multi-color block and upstream's new gradient
  mixed filament warning were inserted at the same spot after the empty
  extruders check. They test unrelated conditions, so both are kept, each with
  its own closing brace.
- tests/libslic3r/test_3mf.cpp -- our three IMEX per-plate round-trip scenarios
  and upstream's mixed-filament round-trip scenario both append to the end of
  the file, and each side added one include. All four scenarios and both
  includes are kept.

Everything else merged cleanly, including GCode.cpp, ToolOrdering.cpp,
PartPlate.cpp and PrintConfig.cpp. Upstream left the is_extruder_used block
untouched, so the IMEX supplement still applies, and estimate_wipe_tower_polygon
is unchanged, so the prime tower hull work is unaffected.

Not addressed here, and worth its own change: a mixed filament is a virtual slot
that no nozzle carries, while physical_extruder_map routes logical slots to
physical heads. Print::extruders() lists mixed slots under their own id whereas
tool_ordering.all_extruders() lists them post-expansion, so the IMEX pem lookups
have no defined answer for a mixed slot. Upstream's own guards reject a mixed
filament where a physical slot is required; IMEX likely wants the same.

Clifford GarwoodandClaude Opus 5 baef398ee3 fix(imex): refuse a plate whose filament cannot reach the mode's primary tool
The IMEX primary tool prints the sliced paths directly, so it can only load a
filament that physical_extruder_map routes to it. The ghost filament picker
enforces that for the secondary tools -- it offers only lanes whose pem entry
equals that head -- but the primary's filament comes from the ordinary object
filament selector, which has no IMEX awareness. Nothing detected the mismatch:
collect_imex_warnings() computes the same condition and discards it into a
display fallback, and the multi-color rule never examines it.

Block it in Print::validate() via the existing imex_primary_tool_for_mode and
imex_primary_logical_from_objects helpers. The message names the declared
primary, the heads the plate's filaments actually live on, and any configured
modes whose primary would work, and carries the object so the notification can
offer a jump to it.

Blocks rather than warns, matching the multi-color rule: the plate is not
printable as configured, and where the routed head is also absent from the
mode's active tools the 1st->2nd layer temperature branch skips it too, leaving
that head at its initial-layer temperature for the whole job.

The multi-color check now runs first. Its constraints -- an MMU manifold sharing
one head, a single-gantry mode -- cannot be fixed by switching mode, so the more
specific error should win rather than be masked by routing advice that leads
straight back to it. The extruders().size() > 1 gate moved onto that call, since
the routing check must also see single-filament plates, which is its common case.

The copy-mode guard-rail test printed on a filament routed off the primary, so
it asserted a plate this rule now refuses; retargeted to a well-formed plate.
Its replacement pins the object's own extruder, because ModelVolume reports its
extruder_id and would otherwise put a primary-routed slot on the plate.

Clifford GarwoodandClaude Opus 5 90d1481463 Merge upstream main into the IMEX work
Upstream replaced MainFrame's fixed-index TabPosition enum with string-based
page ids ("feat: refactor notebook/tabs to be string based instead of fixed
index based"). The IMEX toolhead-visibility menu item was the only consumer of
that enum left on this branch, so its enable check now compares
m_tabpanel->GetSelectedPageName() against TAB_ID_PREVIEW -- the same form the
neighbouring upstream menu items use.

That mismatch is what broke CI: the branch built on its own, but the merge
commit CI builds no longer had TabPosition declared. No other conflicts.

666/666 tests pass in Release.

Clifford GarwoodandClaude Opus 5 ef8d80980d fix(imex): enumerate no secondary carriages in single-tool primary mode
get_imex_active_tools returned every physical head named by the active mode's
tool string, including the one carrying the Primary role. The pressure-advance
and nozzle-temperature sites are already gated on the mode not being primary, so
only the is_extruder_used supplement was exposed.

In primary mode that supplement treated the mode's single declared tool as a
secondary carriage and marked its filament slot used, so machine_start_gcode
emitted a heat command for an extruder that never prints. The phantom slot
appears when the mode's declared tool differs from the head the initial tool
routes to through physical_extruder_map -- on an AFC/MMU layout, printing with a
filament that lives on any head other than the declared one.

Return an empty roster for primary mode, where there are no parallel carriages by
definition. This lives in the enumerator rather than at the call site because the
mode is already resolved and normalized there, and the two guarded callers cannot
reach it in that mode, so their behaviour is unchanged.

Scope: this closes the primary-mode instance. The same phantom slot still occurs
in a parallel mode when the initial tool's head is not the mode's declared
Primary, which turns on which of the two notions of "primary" the three emission
sites should skip. That question is unresolved and deliberately left alone here.

Clifford GarwoodandClaude Opus 5 c94e8324d0 fix(imex): give the printing head its second-layer temperature in parallel modes
The IMEX branch of the 1st->2nd layer temperature transition is mutually
exclusive with the standard per-extruder path in its `else`, but it skipped the
head carrying the print's own toolpaths on the premise that "the standard
per-extruder temp path already addresses it". That path is the `else` branch and
never runs for a parallel mode, so the printing head received no transition at
all and held nozzle_temperature_initial_layer for the entire job.

Emit for every carriage the mode drives, the printing one included. The printing
head takes this layer's own filament; the parallel carriages, which carry no
toolpaths of their own, keep resolving through the per-plate head map with pem
inversion as the fallback. The lookup now goes through get_filament_config_index()
like the standard path, since a variant-expanded printer gives a filament its own
column and a raw index would read the wrong one.

Reproduced on a 4-carriage IQEX in copy mode: the only temperature command in the
whole file set the idle secondary carriage to the value it already had, while the
head doing the printing never left its first-layer temperature. The defect is
invisible whenever initial and regular temperatures match, which is why earlier
per-tool validation passed.

Tests cover both gantry counts, since the active set comes from the mode's tool
roster: an IDEX copy mode drives two carriages, an IQEX mode drives four, and the
IQEX case asserts a first-layer filament and a second-layer transition for each of
the four.
