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.
* 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
OrcaSlicer currently ships an "Octo/Klipper" host type that maps to the
OctoPrint REST endpoints (api/version, api/files/local). It works for
Klipper setups that run Moonraker with the OctoPrint-emulation plugin,
but native Moonraker — and Moonraker-compatible firmwares like the
Prusa-Firmware-Buddy buddy-klipper fork — speak a different shape:
distinct paths, JSON body for /printer/print/start, {"result":...}
envelope. There's no host type for that today.
Add a new Moonraker class deriving from PrintHost. Endpoints used,
matching the Moonraker spec:
- GET /server/info — connection test, reads
result.klippy_state
- GET /server/files/roots — storage-picker dropdown
(returns roots with 'w'
permission); gracefully
degrades if absent
- POST /server/files/upload (multipart) — upload (form fields:
file, root)
- POST /printer/print/start (json) — {"filename":"<path>"}; the
filename is whatever the
upload response returned
in result.item.path, so any
server-side rename
(collision suffix etc.) is
respected. JSON body is
built via property_tree
write_json so exotic
characters in the path are
properly escaped.
Auth: X-Api-Key header, only when printhost_apikey is non-empty
(Moonraker can be configured to require it but doesn't by default).
HTTP Basic / Digest are not part of the Moonraker spec and are not
sent.
Storage root is read from upload_data.storage with "gcodes" as the
fallback default, so the existing storage-picker plumbing in
PrintHostDialogs lights up automatically once enumerable roots are
returned.
UI: registers as the "Moonraker (Klipper)" entry under host_type;
selectable via the existing Physical Printer dialog (sidebar's
connection button on the printer card).
Verified against a Prusa-Firmware-Buddy buddy-klipper fork (firmware
identifies as moonraker_version "0.8.0-prusalink-shim"): /server/info
test, multipart upload to /server/files/upload, and JSON
/printer/print/start all work end-to-end. The existing "Octo/Klipper"
entry is left untouched so users currently relying on Moonraker's
OctoPrint-emulation plugin keep working.
* Add Optimized Gyroid infill (auto-tuned wavelength + amplitude)
New infill geometry derived from FillGyroid. Two parameters are
auto-computed per-region from density, line spacing, and layer height
(no user inputs):
omega = sqrt(density_adj) / sqrt(1 + layer_height/spacing)
clamped to [0.5, 2.0]
-- Euler-Bernoulli buckling: critical load ~ 1/L^2,
so shorter wavelength under higher load (denser infill)
raises buckling resistance.
amplitude = 0.55 / omega^2, clamped to [0.20, 0.65]
-- Curved-beam bending stress: peak stress ~ A * omega^2,
so amplitude is reduced as omega rises to keep peak
fiber stress bounded while preserving stiffness.
Files:
- src/libslic3r/Fill/FillOptimizedGyroid.{hpp,cpp} (new)
- src/libslic3r/Fill/FillBase.cpp (factory case)
- src/libslic3r/Fill/Fill.cpp (switch case)
- src/libslic3r/Layer.cpp (switch case)
- src/libslic3r/PrintConfig.{hpp,cpp} (enum + label)
- src/libslic3r/CMakeLists.txt (build sources)
User-facing: appears as "Optimized Gyroid" in the Fill Pattern dropdown.
Density still chosen by user; omega/amplitude are internal.
* Fix build: layer_height is in FillParams, not Fill base
* Add ipOptimizedGyroid to multiline infill list in ConfigManipulation
* Refactor: replace ipOptimizedGyroid enum with gyroid_optimized boolean
Per @RF47's review feedback, fold the optimized wave math into FillGyroid
itself behind a per-region boolean instead of a separate infill enum.
What changes:
- New ConfigOptionBool "gyroid_optimized" on PrintRegionConfig (default
false). When unchecked, gyroid behavior is byte-identical to before.
- Optimized wave math (compute_omega_factor, compute_amplitude_factor,
f_opt, make_*_opt, make_optimized_gyroid_waves) lives inside
FillGyroid.cpp. _fill_surface_single branches on params.gyroid_optimized.
- FillParams gains a bool gyroid_optimized field, populated in Fill.cpp
from region_config alongside fill_multiline.
- UI checkbox added under Strength > Infill in Tab.cpp, label
"Optimize gyroid wave (experimental)". Toggle is hidden by
ConfigManipulation when sparse_infill_pattern != ipGyroid.
- "gyroid_optimized" added to s_Preset_print_options for preset I/O.
What goes away:
- ipOptimizedGyroid enum value, factory case, switch cases, dropdown
label, string key.
- FillOptimizedGyroid.cpp / FillOptimizedGyroid.hpp (math moved into
FillGyroid.cpp).
- Net diff drops by ~250 lines.
Existing profiles using gyroid are unaffected.
* Wire gyroid_optimized through SurfaceFillParams to FillParams
Linux build failed because line 921 in Fill.cpp populates a
SurfaceFillParams (the dedup struct), not FillParams directly.
Add the field there, in operator< / operator==, and copy it to
FillParams at both conversion sites.
* Use toggle_line for gyroid_optimized: hide row when pattern != gyroid
* Account for multiline wall thickness in omega correction (per @RF47)
When fill_multiline = N, each gyroid wall is N lines thick, so the
geometric scale fed into the buckling correction term should be
spacing * N rather than spacing. Increases omega (tighter wavelength)
when multiline is enabled, consistent with the thicker wall being
more buckling-resistant.
* Optimized gyroid via marching squares on the implicit scalar field
Per @RF47 review: replace the analytical f_opt / make_one_period_opt
wave generator (which had visible kinks at vertical-horizontal
transitions) with a marching-squares iso-extraction on the gyroid
scalar field, modeled on FillTpmsFK.cpp.
- New marchsq::GyroidField in FillGyroid.cpp evaluates
F(x,y,z) = sin(fx*x)cos(fy*y) + sin(fy*y)cos(fz*z) + sin(fz*z)cos(fx*x)
where fx = omega * baseline (anisotropic in x), fy = fz = baseline.
- get_gyroid_polylines() runs marching squares at iso=0 and converts
rings to polylines.
- _fill_surface_single() optimized branch now builds GyroidField,
runs marching squares, and skips the bb.min translate (field
output is already in absolute coords).
- Dropped: f_opt, make_one_period_opt, make_wave_opt,
make_optimized_gyroid_waves, compute_amplitude_factor. Amplitude
has no clean analog in iso-zero extraction.
- Standard (non-optimized) gyroid path unchanged.
* Mass calibration: compensate period by cbrt(omega) for x-anisotropic field
Per @RF47: optimized vs standard gyroid had different masses at the
same sparse_infill_density setting. Cause: scaling fx by omega while
leaving fy=fz at the baseline raised the surface-area-to-volume ratio
by approximately omega^(1/3) (the geometric mean of the three
frequencies).
Fix: multiply the base period by cbrt(omega) so the geometric mean of
(fx, fy, fz) returns to the standard baseline. Net effect:
fx = omega^(2/3) * baseline_orig
fy = fz = omega^(-1/3) * baseline_orig
which preserves total mass at the same density setting while
preserving the load-direction anisotropy this PR introduces.
* Switch optimized gyroid anisotropy from X to Z (per @RF47)
Z is the typical compression-load axis for FFF parts and is not at
delamination risk under compression — so the dominant failure mode
is column buckling of the vertical strands themselves. Tightening
fz directly shortens the effective vertical strand length, which
improves Z-axis buckling resistance.
Mass calibration via cbrt(omega) period compensation still applies
(scaling exactly one of three frequencies by omega; the geometric-
mean preservation argument is symmetric across axes).
* Update src/slic3r/GUI/Tab.cpp
Co-authored-by: Rodrigo Faselli <162915171+RF47@users.noreply.github.com>
* Address review feedback (Copilot + @RF47)
- Fill.cpp: gate params.gyroid_optimized on (params.pattern == ipGyroid)
so non-gyroid surfaces don't differ in SurfaceFillParams by an
irrelevant flag (would unnecessarily split fill batching).
[Copilot suggestion, RF47 confirmed correct]
- PrintConfig.cpp: drop "amplitude" from the tooltip; only wavelength
is parameterized (the marching-squares iso=0 extraction is invariant
to a uniform field scale, so amplitude has no effect).
- FillBase.hpp: shorten gyroid_optimized comment to match the actual
carried state (no amplitude term).
- FillGyroid.cpp: shorten the marchsq namespace comment block; the
ODR concern was overstated (FillTpmsFK uses the same pattern fine).
* Drop redundant marchsq bb expansion (Copilot)
bb is already offset by 10 * scale_(spacing) above for edge-artifact
margin; the second offset on bb_field doubled the raster area for no
geometric benefit and hurt CPU time on large parts.
* Update src/slic3r/GUI/Tab.cpp
Co-authored-by: Ian Bassi <ian.bassi@outlook.com>
* Fix density mismatch + rename to Z-buckling bias optimization
Issue (per @ianalexis): at the same sparse_infill_density setting,
the optimized branch produced denser fill than standard. Verified via
Python sim (sim_gyroid_compare.py) using marching squares on the
implicit field across multiple z slices.
Root cause: the omega formula was inverted from the buckling-physics
intent. The naive sqrt(density_adj) factor produced omega < 1 at
typical print densities (10-30%), which LENGTHENED the Z wavelength
instead of shortening it -- net loss in both mass and strength.
Fix:
- compute_omega_factor: invert to sqrt(1 / density_adj), clamp to
[1.0, 2.0]. Now omega = 2.0 at low density (long strands need
most help) and clamps to 1.0 above ~30% density (no-op, since
standard gyroid is already short enough).
- Remove the cbrt(omega) period compensation. Empirically (sim
table embedded in FillGyroid.cpp comment) the inverted formula
keeps line length per area at ~1.000 of standard across all
densities with no period scaling needed.
Predicted gains (sim, Z-axis Euler buckling proxy):
density line/std strength/std
10% 1.000 2.84x
15% 1.000 1.89x
20% 1.000 1.42x
30%+ 1.000 1.00x (no-op)
Rename per @ianalexis: "Optimize gyroid wave" oversells (now no-op
above 30% density and Z-only). Renamed user-facing label to
"Z-buckling bias optimization (experimental)" with updated tooltip
that scopes to vertical compression and discloses the density cutoff.
Internal config key (gyroid_optimized) unchanged for diff size.
Real-world Instron compression tests at Brown's Prince Lab to follow.

* 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.

# 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.

Previously, wipe tower behavior was determined by checking if the printer
was a QIDI vendor. This introduces a configurable enum (Type 1 / Type 2)
so any printer can select its wipe tower implementation. BBL printers
remain hardcoded to Type 1. Qidi profiles default to Type 1.
Wipe tower interface features and preheat fixes
Fresh PR branch rebuilt on upstream/main (squash of origin/BBL-studio-wipe-tower-merge) to avoid merge-history issues.
Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.
Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
- Add docs/ZAA.md with usage and implementation details
ZAA is opt-in and disabled by default. When disabled, the slicing pipeline
is unchanged.
## Problem
Some Creality printers (e.g. Ender-3 V3 SE) rely on metadata comments in the first lines of G-code files to display print info on the screen (estimated time, filament usage, layer height). This follows a format originally used by Cura/Creality Print:
```
;FLAVOR:Marlin
;TIME:3708.97
;Filament used:6.21m
;Layer height:0.2
```
OrcaSlicer currently has no way to write content before the `HEADER_BLOCK` in the G-code output, and does not expose `print_time_sec` or `filament_length_m` as usable placeholders. As a result, these printers show zeroed-out print info on screen.
## Changes
### 1. New placeholders (post-processing)
Added two new G-code placeholders resolved during post-processing:
- `{print_time_sec}` — total estimated print time in seconds (double)
- `{filament_length_m}` — total filament length in meters (double)
These values are only available after G-code generation, so they use inline marker replacement (`@PRINT_TIME_SEC@`, `@FILAMENT_LENGTH_M@`) that `GCodeProcessor::run_post_process()` substitutes with actual computed values — the same pattern used by existing M73 and layer count placeholders.
### 2. New "File header G-code" option (`machine_top_gcode`)
Added a new G-code field in **Printer Settings > Machine G-code** that writes content at the very top of the output file, before `HEADER_BLOCK_START`. This allows users to add firmware-specific metadata that must appear in the first lines.
### 3. Creality Ender-3 V3 SE profile update
Pre-configured the Ender-3 V3 SE profiles (all 4 nozzle variants) with a default `machine_top_gcode` value matching the Cura-compatible header format, so print info displays correctly out of the box.
# Screenshots

## Tests
- Sliced test model with Ender-3 V3 SE profile
- Verified G-code output contains correct values in first lines:
- `;TIME:` with actual print time in seconds
- `;Filament used:` with filament length in meters
- `;Layer height:` with correct layer height
- Verified `{print_time_sec}` and `{filament_length_m}` work in both Machine Start G-code and File header G-code fields
- Verified empty `machine_top_gcode` produces no extra output
- Built and tested on macOS (arm64)
