Introduces a plugin capability that runs Python at the seams of Print::process(),
letting a plugin read and rewrite slicing state as it is computed.
- New slicing_pipeline_plugin config option; selected plugin refs are serialized
into the print manifest.
- Print gains an injectable hook fired at each pipeline step (posSlice,
posPerimeters, posInfill, ...). It is a no-op when unset, fires only on genuine
(re)computation, and never on the use-cache path.
- orca.slicing submodule: SlicingPipelineCapabilityBase plus a trampoline and a
Step enum. Capabilities read the live graph through zero-copy int64 numpy views
(contour/holes geometry with unscaled coordinates, flattened toolpath data) and
edit it through 2D-geometry mutators with cache-invariant refresh.
- GUI dispatcher runs capabilities during slicing under the GIL, turns plugin
errors into slicing errors, honors cancellation, and adds the plugin picker.
- Ships the InsetEverySlice sample plugin and binding/hook tests.
Catches the iXex/IDEX branch up to upstream main (44 commits). One
content conflict resolved:
- src/libslic3r/Print.hpp: kept upstream's default-initialized
m_origin {0,0,0} alongside our m_imex_slice_offset member.

Catches the iXex/IDEX parallel-printing branch up to upstream main
(102 commits). Two content conflicts resolved:
- src/libslic3r/Preset.cpp: s_Preset_printer_options — kept upstream's
new "use_3mf" key and our iMEX printer-capability/mode keys.
- tests/fff_print/test_gcodewriter.cpp: upstream revived the disabled
suite (#14196), dropping the obsolete [.]-tagged lift() test and its
config_lift_unlift.ini; kept their set_speed + z_hop tests and appended
our 10 per-firmware set_pressure_advance/set_temperature scenarios.

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.

* feat: add support for 3MF file format in printer configurations and export options
* fix file extension
* enable 3mf for X Max 4
* disable use_3mf for X Plus 4
* Fixed an issue where `label_object_enabled` was not properly propagated to 3mf
* enable exclude object for Max 4
* remove hardcoded use 3mf for flashforge, move them to the new printer profiles config
* Fix null-deref and arranger bugs that gate headless slicing tests
export_gcode dereferenced a null result out-param, enum serialization
dereferenced a null keys_map, and get_arrange_polys left bed_idx unseeded so
the arranger dropped items. All only affect the headless test/CLI path.
* Fix the headless test harness and add G-code test helpers
Use the real arranger, fix temp-file handling with an RAII guard, and add
layers_with_role / max_z for inspecting sliced G-code.
* Re-enable the Model construction test
* Re-enable SupportMaterial tests and add an enforced-support test
* Re-enable and extend PrintObject layer-height and perimeter tests
* Re-enable Print skirt, brim, and solid-surface tests
* Re-enable and extend PrintGCode tests
Un-hide the basic scenario (dead-key fixes, reframes, trimmed trivia) and add
initial-layer-height, sequential-order, and null-result export tests.
* Re-enable and reframe the skirt/brim tests
Detect skirt/brim by G-code role comment instead of a sentinel speed, and
resolve the previously-unfinished skirt-enclosure test.
* Replace the stale lift()/unlift() test with a z_hop test
* Delete the stub and broken Flow tests
The original PR skipped the max-print-height check entirely on belt printers
because the sliced (virtual) Z is belt travel, not build height. As the reviewer
noted, that removed the only working height guard. Restore a correct guard:
- Print::validate: on belt printers, compare the upright object height
(max over instances of the scene-space bbox) against printable_height directly.
printable_height is the usable VERTICAL clearance above the belt: the gantry
travels up the tilted plane (reach = height/cos(tilt)) and its axis range is
sized for that (IR3 V2: ~354 mm gantry travel = 250 mm vertical at 45deg, and
printable_height = 250). Hardware-confirmed 250 mm vertical clearance, so no
cos(tilt) factor is applied.
- BuildVolume::set_belt_printer: drop the diagonal Z scaling; the build-volume Z
already equals printable_height, keeping the live 'outside build volume'
highlight in agreement with validate().

* Fix junction deviation and jerk settings behavior
Process settings now follow the selected printer's junction deviation
configuration. When machine_max_junction_deviation is enabled,
default_junction_deviation is shown and jerk settings are hidden. When
junction deviation is disabled, jerk settings are restored and
default_junction_deviation is hidden.
Fix a validation issue where junction deviation mismatch warnings could
be reported even when machine_max_junction_deviation was set to 0.
Warnings now apply only when junction deviation is active and point
directly to default_junction_deviation.
Also simplify Motion ability page visibility checks by reusing local
firmware-flavor booleans.
* GUI tweak
- separate Junction Deviation segment
- JD and Jerk stay visible

in Plater.cpp alongside the existing IMEXHelpers include), profile fixes
and version bumps (#14084, #14085, Polymaker), CI artifact publishing,
test refactors (arachne walls test added; test_3mf/test_config/
test_gcodewriter content moved/removed upstream — IMEX test file
preserved as it is feedback-only), translations.
Includes nozzle-diameter guards for printers without nozzle info (#13255,
now landed upstream) and manual-calibration nozzle mismatch fix (#13882).

* fix: restore version placeholder in custom G-code
PlaceholderParser sets "version" in its constructor, but Print::apply() calls clear_config() which wipes it. Unlike timestamp/user (restored during G-code export), version was never restored, so [version]/{version} threw "Variable does not exist" in custom G-code while working in output filenames.
Re-set version after both clear_config() calls so it resolves everywhere.

* fix: resolve timestamp and user placeholders in File header G-code
file_start_gcode is processed via print.placeholder_parser() directly, before the G-code parser integration copy that restores timestamp/user. As a result {timestamp}, {year}..{second} and {user} threw "Variable does not exist" in the File header G-code field while working in Machine start/end G-code.
Inject fresh timestamp and user into the file_start_gcode config so they resolve, matching the other custom G-code fields.

* fix: expose initial_extruder and extruded_*_total placeholders in output filenames
PrintStatistics exposed initial_tool (not its documented alias initial_extruder) and total_weight/extruded_volume (not the documented extruded_weight_total/extruded_volume_total). Filename formats using the missing names failed with "not a variable name".
Add the missing aliases to PrintStatistics::config() and placeholders().

* Sync Elegoo profiles from ElegooSlicer
Update vendor Elegoo.json, filament/machine/process trees, and OrcaFilamentLibrary
Elegoo entries. Align machine default material names with existing filament preset names.
* feat: expose filament_name for G-code export filename format
Derive from filament_settings_id for the first active extruder and strip the suffix after @, matching ElegooSlicer so filename_format can use {filament_name}.
* chore: reorder Elegoo entries in OrcaFilamentLibrary
Group Elegoo @base profiles and bump library version to 02.03.02.62.
* sync OrcaFilamentLibrary.json with Elegoo filament profiles
* fix: clean up Elegoo process renamed_from for profile validation
Add single renamed_from only where preset names changed from legacy Orca
names; remove duplicate Rapid @System library entries that conflicted with
ECC2 vendor presets.
* fix(profiles): add missing Elegoo renamed_from for profile validation
CI custom-preset tests still inherit legacy Orca preset names that no
longer exist after the Elegoo bundle update. Add renamed_from on process,
Neptune 4 machines, OrcaFilamentLibrary filaments, and Giga profiles so
inherits resolve again, without changing print parameters.
Reconciles the belt-printer branch with upstream PRs through #13723. Six
files had conflicts; three additional files needed manual follow-up fixes
where the auto-merge produced code that referenced upstream-renamed fields
or changed function signatures.
Notable reconciliations:
- TreeSupport.cpp: kept belt-floor early-exit branches around HEAD's
drop-down logic, folded upstream's `(distance_to_top > 0 ? 1 : 0)`
formula into the non-belt-floor path (upstream PR #11812). Dropped dead
`roof_enabled`/`force_tip_to_roof` locals.
- TreeSupport3D.cpp: combined upstream's safety-offset + remove_small
changes with HEAD's belt-floor clip in the per-slice trim loop. Dropped
HEAD's `else` block (superseded by upstream's rewritten bottom-contact
propagation) and re-added the belt-floor clip into the new propagation
loop. Gated the propagation on belt printers to prevent OOM when
belt-floor clipping produces empty initial slices.
- TriangleSelector.{cpp,hpp}: merged both new `select_patch` parameters
(HEAD's `up_direction` and upstream's `select_partially`); body uses
`dot(up_direction)` for the overhang angle check and forwards
`select_partially` to `select_triangle`.
- SupportMaterial.cpp: `slicing_params.soluble_interface` →
`zero_gap_interface_bottom` in HEAD's `detect_belt_floor_bottom_contacts`,
matching upstream's same-purpose rename at line 2495.
- Custom.json, GCodeWriter.cpp: simple additive merges (kept entries /
includes from both sides).
Verified by building OrcaSlicer (RelWithDebInfo) after a full deps
rebuild (Eigen v5.0.1, libigl v2.6.0 are now managed deps) and slicing
a scaled Benchy on the NORMALIZER belt-printer profile without OOM.
