Filament grouping already consumed per-filament forbidden nozzle volume
types, but every call site passed an empty map, so a variant-restricted
filament (e.g. one limited to "Direct Drive TPU High Flow") could be
auto-grouped onto an incompatible nozzle flow type on multi-variant
printers.
- add convert_to_nvt_type() to parse extruder variant strings
- add Print::get_filament_unprintable_flow(): forbidden volume types =
printer extruder variants minus the filament's declared variants;
filaments declaring no variants stay unrestricted
- feed the map into grouping at the by-object path (Print.cpp) and all
six mapping/planning sites in reorder_extruders_for_minimum_flush_volume
- unit-test the string parser
Non-restricted configurations produce an empty map, so existing
printers' grouping and g-code are unchanged.
Adds PluginHostSlicing, which registers the print-graph data model (Print,
PrintObject, Layer, LayerRegion, Surface, ExPolygon, extrusions, ...) into the
orca.host submodule in the same raw-class style as PluginHostApi's Model/Preset
graph, with shared helpers in PluginBindingUtils. SlicingPipelinePluginCapability
is trimmed to the capability surface (the standalone SlicingNumpy helper is folded
away). Adds the Twistify example plugin next to Inset and broadens the binding,
hook, and plugin-install tests.
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
* 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

* 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.
Adds the `imex_firmware_managed_zones` printer-config key (default off) for
IDEX/IQEX printers whose firmware applies its own copy/mirror offsets in
non-primary modes (e.g. RepRapFirmware IDEX duplication mode, Flashforge
Creator Pro 2/3 Pro). For these printers the slicer needs to emit a single
centered slice at bed origin and let the firmware fan toolheads out from there;
the previous slicer-managed iMEX rendering would draw a print at the primary
zone's world position (off-bed for the firmware-fan-out paradigm).
When the flag is on and the active mode is non-primary, the slicer subtracts
the primary zone's plate-local center from the gcode emission frame. The
writer offset is augmented but the gcode-processor offset stays at plate_origin
so the gcode-preview visualizer renders the centered slice at the bed center
rather than at the prepare-view zone placement. translate_to_print_space is
augmented too so first_layer_print_min/max placeholders (consumed by user
start_gcode like Felix's M118 header) reflect the centered frame.
Slice handoff lives in PartPlate::refresh_imex_slice_offset, called from both
update_slice_context (plate switch) and Plater::priv::update_background_process
(every-slice path — reslice() goes through here with switch_print=false so the
plate-switch hook alone wouldn't fire on mode toggle).
calc_imex_ghosts early-returns in firmware-managed mode: the existing
imex_head_transform math places ghosts at primary_zone_center + gantry_offset
(slicer-managed semantics), which renders off-bed when the toolpath is being
emitted in a centered frame. Proper firmware-managed ghost rendering (showing
where copies/mirrors will actually print after firmware fan-out) is deferred.
When the flag is off, all the new code paths reduce to no-ops byte-identical to
prior behavior. Layer 1 unit tests in test_imex_helpers cover every gating path
of compute_imex_slice_offset; full ctest suite passes (247/247).

* Make filament compatibility temperature-aware
Extend filament compatibility checks to consider actual nozzle temperatures and temperature ranges.
Print::check_multi_filaments_compatibility now accepts nozzle temperatures and range lows/highs; it resolves missing ranges from material defaults, computes per-filament effective temperatures, and checks pairwise compatibility (including high/low/mid mixed cases).
Updated callers in Print::check_multi_filament_valid and CalibrationWizardPresetPage to pass nozzle settings, consolidated user-facing warning strings, and fixed extruder index handling and minor logic/path improvements.
Clarify incompatible nozzle temperature warnings
* Update Print.cpp
* Remove json usage
* Reduce messages
The mode-type tag (imex_mode_types config + imex_mode_type_for helper +
Split sentinel) was added in 0bb1cef as scaffolding for the Split rendering
work that landed in 4370cca and then got reverted in d9be71b. With Phase 2-4
gone, this scaffolding is now unused dead code — and the design we settled
on instead is to leave topology entirely implicit (parsed from active_tools_str)
rather than carrying a per-mode type tag the user would otherwise have to
manage explicitly.
The multi-color slicing block + bare T<n> suppression that were the actual
substance of the safeguards work stay in place:
- imex_multicolor_block_reason still allows multi-color exactly when 2+ tools
are active on the primary's gantry — Felix's hypothetical IQEX paired-gantry
case works through this path, no new mode type required.
- Slicer-side: bare T<n> stays suppressed at print-start in IMEX parallel modes;
mid-print T<n> emits naturally for the legitimate IQEX 4-tool-active scenario.
Removed:
- ConfigOptionStrings imex_mode_types (PrintConfig.hpp/cpp + Preset.cpp key list)
- imex_mode_type_for helper + kImexModeType{Primary,Copy,Mirror,Split} sentinels
- mode_type parameter on imex_multicolor_block_reason and the Split short-circuit
- mode_type plumbing in Print::validate and PartPlate::has_imex_multimaterial_conflict
- Three unit tests for imex_mode_type_for + two Split-specific multicolor block tests

Felix14-v2 PR review feedback (https://github.com/OrcaSlicer/OrcaSlicer/pull/13086#issuecomment-4323696312)
plus the slice-time validation work that follows from his bug list.
UI polish:
- Capitalize "Primary" in display (right-click mode menu, plate tooltip).
Sentinel stays lowercase for wire compatibility.
- Pre-slice-warnings checkbox now uses Orca's ::CheckBox so it matches the
green toggle style of the rest of the IDEX/IQEX configuration page.
- DPI-scaled the IMEXModesCtrl (modes editor) sub-panels, button grid,
text wraps, gcode textarea, and the ghost-tooltip swatch (imgui.scaled).
Legend swatches sized to body-text height for visual balance.
- Primary mode tool buttons in the modes editor are now disabled (read-
only): cycling roles on the IMEX-off mode is a no-op and confusing.
- Modes editor sub-panels now explicitly inherit the app's window-default
dark colour so chromeless ScalableButtons don't render with a visible
light box around their icons on GTK dark themes.
- Per-mode-line reset arrows in the modes editor: each row gets a small
reset bitmap that snaps that row's name+tools+gcode triplet back to the
saved preset's value. matches_config() guard on the page-level reload
prevents the textbox-being-typed-into from being destroyed mid-keystroke.
- New View menu item "Show IDEX/IQEX Toolhead" — toggles the per-carriage
footprint boxes during G-code preview playback. Gated to Preview tab +
IMEX printer; backed by app_config so it persists.
Coordinated config migrations:
- imex_tool_layout and imex_viz_theme migrate from coString to coEnum
(ImexToolLayout / ImexVizTheme). Existing wire format preserved so
saved presets and 3MFs deserialize unchanged. Side-benefit: both now
pick up standard Field rendering and so finally show reset arrows.
Slice-time safeguards (the validation half):
- imex_suppresses_bare_toolchange(parallel_mode, count): suppresses the
slicer's bare T<n> at print-start in any IMEX parallel mode (the user's
imex_mode_gcode + machine_start_gcode owns tool activation there). Mid-
print T<n> emits normally — Print::validate blocks the configurations
where mid-print T<n> wouldn't make sense. Applied to both code paths
inside GCode::set_extruder (the long multi-extruder path AND the
single-extruder path that fires when multiple_extruders=false).
- imex_multicolor_block_reason(): hard-stop validator returning a user-
facing reason string when the active IMEX configuration can't physically
support multi-color. Catches IDEX (1 tool/gantry), 2-tool-active IQEX
(no within-gantry swap topology), and any MMU/AFC lane sharing among
used filaments. Wired into Print::validate as a slice blocker, and into
PartPlate::has_imex_multimaterial_conflict so the plater badge agrees
with the slice block (no more false positives where the badge warns but
the slice goes through).
- New imex_mode_types config option (parallel array to imex_mode_names)
and imex_mode_type_for() helper. Mode-type tag drives behaviour: zones,
ghosts, and validation interpret modes differently per type. Initial
types: "primary", "copy", "mirror", "split". Split modes are explicitly
designed for paired-gantry IQEX multi-color and bypass the gantry-pair
check in imex_multicolor_block_reason (MMU sharing still blocks them).
Test coverage:
- New unit tests cover imex_suppresses_bare_toolchange (4 cases),
imex_multicolor_block_reason (8 cases including IDEX, IQEX 2-/4-tool-
active, MMU sharing, missing primary, Split type), and imex_mode_type_for
(3 cases including legacy fallback). Total: 186 IMEX assertions across
71 test cases, all passing.

* Fix: Enable instance collision detection in GCode and Print clearance
Squashed commit containing:
- Fix gcode path conflict detection in ConflictChecker.cpp by iterating all instances.
- Improve clearance validation in Print.cpp by calculating convex hulls per instance (fixes scaling/mirroring issues).
- Added // Orca: comments to mark changes.
* Fix Wipe Tower G-code conflict detection for WipeTower2
* Fix: Improve object/instance selection for collision and validation warnings
- Updated validation logic in Print.cpp to report specific ModelInstance instead of ModelObject for collision/clearance warnings.
- Updated NotificationManager and Plater to handle ModelInstance selection in 'Jump to' links.
- Added fallback to object selection if specific instance cannot be selected.
- Included fixes for G-code conflict detection (ConflictChecker, GLCanvas3D) to also report instances.
- Improved GUI_ObjectList to update canvas selection when items are selected via API.
* Fix: Prevent crash when loading .3mf projects
Moved update_selections_on_canvas() out of ObjectList::select_items() to avoid premature UI updates during loading. Canvas updates are now explicitly called in NotificationManager and Plater callbacks where needed.

# Description
This commit adds the enhancement of https://github.com/OrcaSlicer/OrcaSlicer/issues/13116
- Adds checkboxes to enable or disable the fan speed override during print or after printing is completed. This allows users to, for example, only override the fan speed during printing whilst leaving the fan speed as is set in the machine gcode at the end.
- Two new flags are added for this: `activate_air_filtration_during_print[extruder]` and `activate_air_filtration_on_completion[extruder]`. These can be used to more finely control machine gcode
- Current filament settings remain as they are: `activate_air_filtration[extruder]` settings are unaffected and by default both new flags are set to true, ensuring the same set behavior as before.
# Screenshots/Recordings/Graphs
<img width="856" height="208" alt="Screenshot From 2026-04-09 18-57-14" src="https://github.com/user-attachments/assets/e71e7de3-2def-4046-b5dc-55bf3b516ce5" />
As you can see there are now checkboxes left of the fan speeds. They have their own tooltip too, which also helps identify the correct flags for users who want to adjust their machine gcode.
## Tests
I have thoroughly tested this on my own computer (CachyOS) and on my printer. I have also carefully checked the gcode in every possible state this is in and ensured that the unsaved changes dialog properly displays the labels for these settings. Flags are set properly, sliced files properly use the flags if you check for them in machine gcode and default behavior is unaffected for those who have already changed settings for air filtration. From what I can see, this does exactly what it should be doing without any issues.
* make initial layer travel move acceleration and jerk configurable
* Update spelling to match UI pattern
* Update min integer and re-order to match patterns

In some cases, this increases the number of tabs due to the new lines, but the increase is negligible, and this way both the base profiles and those created by Orca maintain the same style.
