An extruder with more than one physical sub-nozzle can hold a mix of
Standard and High Flow nozzles. The Flow dropdown now offers Hybrid for
such extruders (extruder_max_nozzle_count > 1, nil-guarded); grouping
already expands a Hybrid extruder into per-volume nozzle groups from
extruder_nozzle_stats.
- sidebar Flow combo offers Hybrid only for multi-sub-nozzle extruders
- preset lookup treats Hybrid as Standard (presets define no Hybrid
variant); variant strings are never fabricated for it
- printer tab splits a Hybrid extruder into Standard + High Flow rows,
with matching selection-index arithmetic and sync-enable rules
- syncing from a printer whose extruder holds mixed nozzle flows now
selects Hybrid instead of collapsing to the dominant flow type
- send-to-printer flow check: a nozzle-rack extruder validates its
nozzle inventory (mounted + rack) against every needed flow instead
of comparing only the mounted nozzle; mounted-flow lookup is now
per-extruder, fixing an index shift when a nozzle reports no flow
- Hybrid is session-only in app config (stored as Standard), so a
fresh session starts from concrete flow types
Printers whose extruders have a single sub-nozzle (including all
dual-extruder machines without a rack) see no new option and identical
check behavior.
cooling_filter_enabled existed as a config option but was shown nowhere,
and there was no capability flag to gate it. The cooling filter and air
filtration are alternative accessories sharing the same duct, so a
printer declares one or the other.
- new hidden printer capability flag support_cooling_filter
- "Use cooling filter" toggle in the Accessory group, shown only when
the printer supports it; the air-filtration toggle hides in that case
(no vendor restriction: third-party printers keep air filtration)
- explicit defaults (0) in the common machine base
- H2C declares support_cooling_filter=1 instead of support_air_filtration;
its start-gcode already carries the cooling-filter conditional, so the
toggle is functional. On H2C this drops the two exhaust-fan lines that
air filtration emitted for ABS-class filaments, matching the printer's
actual duct accessory; H2C is new on this branch so no existing user
output changes.
Printers without the flag keep exactly the previous accessory UI and
g-code.
New printer option fan_direction (undefine/left/right/both, default
undefine) declares which side the auxiliary part-cooling airflow comes
from. When set and the printer has an auxiliary fan, auto-orient adds a
yaw rotation so the dominant overhang area faces the airflow, and newly
added primitive shapes are pre-oriented the same way (except the Cube,
whose axis-aligned bounding box the pressure-advance pattern calibration
depends on).
- FanDirection enum + fan_direction printer option (Accessory group,
enabled only with auxiliary_fan)
- orient engine: weighted overhang areas per candidate, yaw-direction
search, vertical rotation applied on top of the primary orientation;
the cooling weights are taken from the candidate actually chosen,
including the flat-bottom tie-break
- orient_for_cooling() for primitive placement
- set fan_direction=left on H2C/H2D/H2D Pro/X1/X1E/P1S 0.4 profiles
(X1C/H2S/P2S/X2D/Qidi X-Max 4 already carried the key, which now
takes effect)
With fan_direction unset or no auxiliary fan the vertical rotation stays
identity and auto-orient results are unchanged; slicing and g-code are
never affected.
The engine already implements prime_volume_mode (Default/Saving/Fast)
but nothing in the UI could set it, leaving prime-saving unreachable on
multi-sub-nozzle extruders and fast purge unreachable on printers that
support it.
- new PurgeModeDialog with selectable Standard/Fast or
Standard/Prime Saving cards depending on printer capability
- "Purge mode" sidebar button next to Flushing volumes; opens the
dialog and stores the choice in the project config
- printer preset-load gating: button shown only when the printer has
multiple sub-nozzles per extruder or sets support_fast_purge_mode;
stale project values the printer cannot honor reset to Default
- enable fast purge on A2L 0.4 (support_fast_purge_mode), explicit
default 0 in the common machine base
- new dialog strings added to OrcaSlicer.pot
Printers without these capabilities never show the button and their
projects keep prime_volume_mode at Default, so slicing output is
unchanged.
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.

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.
* Support 'Default' filament option (index 0)
Treat filament index 0 as the new "Default" (use active object/part filament) instead of using 1. Update config defaults and tooltips for wall/sparse/solid infill filament options (min/default -> 0, tooltip explains "Default"). Adjust normalization and propagation logic to respect explicit feature overrides and only apply base extruder when feature values are zero; only copy sparse->solid infill when sparse > 0. Introduce FeatureFilamentOverrideMask and clamp_feature_filament_to_valid to resolve and clamp feature filaments. Update UI lists and selection behavior to expose a "Default" entry and handle zero-based indices in PartPlate and Plater.

* Allow wipe_tower_filament to equal nozzle count
Relax the assertion in Print::extruders to permit wipe_tower_filament == config().nozzle_diameter.size(). The configuration value is 1-based and the code subtracts 1 when pushing the extruder index, so equality should be valid and selecting the last nozzle should not trigger an assertion.
* Revert "Allow wipe_tower_filament to equal nozzle count"
This reverts commit 2c976574327a8bcdc74a1b296bf1aaff7752a94e.
* Revert "enable_filament_for_features option"
This reverts commit 01c13baeddb8e26793f752deab788ee4d086975b.
* Migrate legacy feature filament defaults
Add migration logic to convert legacy feature filament selections from 1 to 0 for older 3mf files. Introduces a local migrate_legacy_feature_filament_defaults lambda in src/OrcaSlicer.cpp and src/slic3r/GUI/Plater.cpp that scans keys (wall_filament, sparse_infill_filament, solid_infill_filament, support_filament, support_interface_filament) on configs/objects/volumes, updates values, counts conversions and logs the result. Also adds a Semver check for "2.4.0-dev" in OrcaSlicer to trigger the migration for files older than that version. This preserves expected default filament selections when loading older project files.
* Update OrcaSlicer.cpp
* Extract migration helper to ConfigMigrations
Centralize legacy feature-filament default migration by moving the duplicated lambda into ConfigMigrations::migrate_legacy_feature_filament_defaults (src/libslic3r/Config.cpp) and declaring it in Config.hpp. Update OrcaSlicer.cpp and slic3r/GUI/Plater.cpp to call the new function instead of inline lambdas. The helper converts specific feature filament keys (wall_filament, sparse_infill_filament, solid_infill_filament, support_filament, support_interface_filament) from int 1 to 0 and returns the count of conversions to avoid duplicated migration logic.
* Remove DynamicFilamentList1Based and consolidate lists
Delete the specialized DynamicFilamentList1Based struct and its global instance. Update Choice registrations to use the single dynamic_filament_list for wall, sparse_infill and solid_infill filaments, and remove the extra update call for the removed instance. This consolidates filament choice handling and removes duplicated logic in Plater.cpp.
* move it
* fix objects
* Update Config.hpp
* Update profiles
* Add Flashforge AD5X local send dialog, IFS mapping, and LAN discovery
* Refine Flashforge AD5X IFS dialog behavior
* Refine Flashforge IFS slot selection dialog
* Fix Flashforge printer selection and print mapping
* Use 3MF for Flashforge local uploads
* Generalize Flashforge local API handling
* Handle Flashforge local API IFS support more robustly
* Use selected plate filament info for Flashforge IFS mapping
* Fix Flashforge current-plate mapping and widget sizing
* Improve Flashforge IFS contrast and color matching
* Fix Flashforge legacy plate export and upload naming
Resolve PLATE_CURRENT_IDX before the legacy send-to-printhost path calls send_gcode so single-plate Flashforge 3MF exports target the selected plate instead of leaking the sentinel into export_3mf.
Sanitize Flashforge upload names in one shared utility reused by both the dialog and the backend client. This keeps the UI-visible filename and the actual uploaded filename consistent and replaces printer-problematic characters such as '=' without scattering Flashforge-specific logic through the generic Plater flow.
* Keep Flashforge upload filename sanitization in the backend only
Drop the PrintHostSendDialog API changes and keep filename sanitization inside the Flashforge backend paths that actually talk to the printer. This keeps the generic send dialog flow untouched while still normalizing problematic upload names for both serial and local API uploads.
* Only use the Flashforge IFS dialog for local API uploads
* Use reported Flashforge IFS support without model fallback
* Remove unused Flashforge slot uniqueness tracking
* Include <array> for Flashforge discovery message
