* 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 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
Enables supported printing of standard Orcaslicer calibration profiles.
* Build 2 Checkpoint

* make temp towers work
* re-enable spiral on calibrations that want it
* Final cleanup pre-PR and community testing
collect_layers_to_print() warns (CRITICAL) when an extrusion layer sits above
the previous one with an empty gap below — the fixed-bed assumption that
material with nothing under it is floating and unprintable. On a belt printer a
*leading* empty range (the gap starts at Z=0, no prior extrusion layer) is not
floating: it is the conveyor lead-in, and the part rests on the advancing belt
as the first material is laid down well above Z=0. A part not designed for a
belt (e.g. a flat test model tilted into the belt frame) then trips this as a
false "Object can't be printed for empty layer between 0 and N" error.
Suppress only the leading case (belt_printer && last_extrusion_layer == null);
genuine internal gaps are still flagged, since on a belt those can be an
over-angle overhang printing into air. Non-belt output is unchanged.
* Preserve support base outline/fill order
Honor no_sort when emitting support toolpaths to keep outline-first order.
Group tree support base paths (including lightning) into per-area no_sort collections to prevent interleaving across islands.
Keep lightning layer lookup side-effect free.
* Tag Orca specific changes
Tag Orca specific changes vs. Bambu using the comment //ORCA: . This helps when reviewing merge commits from upstream Bambu so we don't end up causing regressions when pulling in commits from upstream
* Fix air filtration gcode emitted even if not not supported
- do not emit air filtration gcode if not supported by the printer
- removed redundant "add_eol" parameter from "set_exhaust_fan()" function
* 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().

* fix: populate total_toolchanges without a wipe tower
total_toolchanges is documented as available while change_filament_gcode (and the wipe-tower toolchange flow) is evaluated, but it was sourced only from WipeTowerData::number_of_toolchanges, which stays -1 (clamped to 0) when no wipe tower is generated. Manual filament swaps and toolchanger/IDEX setups without a wipe tower therefore always saw total_toolchanges = 0 in custom G-code and output filenames, despite real tool changes occurring -- breaking the placeholder's documented contract.
Add a tool-ordering fallback: when number_of_toolchanges < 0, count tool changes from the print's tool ordering (the transitions in the per-layer extruder sequence). Wipe-tower prints are untouched -- number_of_toolchanges >= 0 still wins -- so their reported count does not change.
Limitation: sequential (by-object) prints without a wipe tower leave Print::tool_ordering() empty, so total_toolchanges stays 0 there (unchanged from before).

* feat(viewer): Display travel distance and move count in G-code summary
This commit introduces a new feature that enhances the G-code viewer by displaying the total travel distance and the total number of travel moves in the 'Line Type' summary.
This provides users with more detailed statistics about their prints, helping them to better understand the printer's behavior and identify opportunities to optimize travel moves for faster print times.
This commit also fixes a critical bug in the G-code processor where the travel distance was being calculated incorrectly. The distance variable was not being updated for non-extruding travel moves, leading to inaccurate statistics. The calculation has been corrected to ensure it is performed for all relevant move types, resulting in accurate travel distance reporting.
* Subfix segments
kilo mega giga tera peta exa
* Add missing values
* Grams to Kilos and tons
* add distance
* Fix tool view
* Record and display seam distances
Track seam-related distances in print statistics and show them in the GCode viewer. Added total_seam_gap_distance and total_seam_scarf_distance to PrintEstimatedStatistics (with initialization). In GCode::extrude_loop the code now computes seam gap and scarf distances and accumulates them for external perimeters. GCodeViewer uses the summed seam distance when the Seams option is selected in the legend.
* Fix travel / wipe distances
* Update GCode.cpp
* Filament changes estimated time

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.

Conflicts resolved in src/libslic3r/GCode.cpp and src/slic3r/GUI/GUI_Factories.cpp.
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

Fix extrusion of some support layers at wrong Z height
Fixes the issue that PR #12736 (github.com/OrcaSlicer/OrcaSlicer/pull/12736) reverted the changes of PR #13327 (github.com/OrcaSlicer/OrcaSlicer/pull/13327)
This PR supersedes #12225, which originally proposed this feature but
appears inactive.
The feature originated from work I developed earlier in
[BambuStudio-ZAA](https://github.com/adob/BambuStudio-ZAA), a private
fork of Bambu Studio
Compared to #12225, I updated the implementation for current upstream
and fixed the following issues:
- fixed broken tests
- removed references to nonplanar directory
Reviewers may want to compare against #12225 for earlier
discussion/context.
## Summary
Port of **Z Anti-Aliasing (ZAA)** from
[BambuStudio-ZAA](https://github.com/adob/BambuStudio-ZAA) to
OrcaSlicer.
ZAA eliminates visible stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and
micro-adjusting its Z height to follow the actual surface geometry. The
result is visibly smoother domes, chamfers, and shallow slopes — without
post-processing.
## How It Works
1. The slicer runs normally, then a **posContouring** step processes
each layer
2. `ContourZ.cpp` raycasts every extrusion point vertically against the
source mesh
3. Each point's Z is adjusted to the mesh intersection, converting flat
`Polyline` paths into `Polyline3` paths with per-point Z coordinates
4. The G-code writer emits the adjusted Z values, so the printer follows
the true surface
## Configuration
Five new settings under **Print Settings > Quality**:
| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `zaa_enabled` | bool | off | Master enable/disable switch |
| `zaa_min_z` | float | 0.06 mm | Minimum Z layer height; controls
slicing plane offset |
| `zaa_minimize_perimeter_height` | float | 35° | Reduce perimeter
heights on slopes below this angle (0 = disabled) |
| `zaa_dont_alternate_fill_direction` | bool | off | Keep fill direction
consistent instead of alternating |
| `zaa_region_disable` | bool | off | Disable ZAA for a specific print
region/material |
## Key Changes
- **Core algorithm**: New `src/libslic3r/ContourZ.cpp` (~330 lines) —
raycasting engine
- **3D geometry**: `Point3`, `Line3`, `Polyline3`, `MultiPoint3` extend
existing 2D types
- **Arc fitting**: Templated to work with both 2D and 3D geometry
- **Pipeline**: `ExtrusionPath::polyline` changed from `Polyline` to
`Polyline3`; new `posContouring` step in `PrintObject.cpp`
- **G-code**: `GCode.cpp` writes per-point Z when `path.z_contoured` is
set
- **UI**: ZAA settings exposed in Print Settings > Quality panel
- **Documentation**: `docs/ZAA.md` with usage and implementation details
57 files changed, ~1800 insertions, ~200 deletions.
## Test Plan
- [ ] Load a model with curved top surfaces (sphere, dome, chamfered
box)
- [ ] Enable **Z contouring** in Print Settings > Quality
- [ ] Slice and verify G-code has varying Z values within contoured
layers
- [ ] Build on macOS (verified), test on Linux and Windows
* Add extrusion role change G-code options
Introduces new G-code options for handling extrusion role changes at the process and filament levels. Updates configuration, GUI, and GCode logic to support 'process_change_extrusion_role_gcode' and 'filament_change_extrusion_role_gcode', allowing custom G-code insertion when the extrusion role changes.

* Optimize extrusion role-change gcode handling
Cache gcode template strings and current filament id, and guard creation of DynamicConfig/placeholder processing behind a check that at least one role-change gcode is non-empty. This avoids redundant config lookups and DynamicConfig/placeholder parsing when no custom role-change gcode is defined, improving clarity and performance without changing behavior.

In some rare support edge cases, Orca could start extruding a new layer before moving to the correct Z height.
This happened when two support layers were generated back-to-back and the next layer started exactly where the previous one ended. In that situation, there was no movement that naturally updated the Z position first.
The code was clearing the “pending layer change” flag too early, so it lost track of the fact that a Z move was still required.
This change ensures that if a layer change is still pending, Orca will always move to the correct Z height before the first extrusion of that layer.
This guarantees that every layer starts at the correct height and fixes the missing / incorrect support layers seen in those edge cases.
Adjust initial- and slowdown-layer speed logic to correctly account for raft layers. Replace the previous layer checks with object_layer_over_raft(), simplify initial-layer speed selection, and split the slow_down_layers interpolation into separate branches for configurations with and without rafts so the lerp uses the correct layer offset. Also avoid applying overhang speed adjustments to object layers that are over rafts.
# 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
