Fix Ender-3 V3 KE nozzle switching by adding printer_variant
The four Creality Ender-3 V3 KE 0.X nozzle profiles were missing the
printer_variant key, so OrcaSlicer could not map a UI nozzle selection
to a specific profile and reverted every choice to 0.2mm. Add the
matching printer_variant to each, following the CR-10 SE / K1C pattern.
Introduce an 'indentation_check' job step to .github/workflows/check_profiles.yml that validates profile JSON files under resources/profiles use tab-only indentation (1 tab per level). The step runs an inline Python check, emits a log (indentation_check.log) with errors and a fix tip, and exits non‑zero on violations. Workflow conditionals for preparing the PR comment artifact, uploading the artifact, and failing the job were updated to include the new step so indentation failures are reported alongside other profile validation failures.
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)
# Description
With this change, builds on ARM64 hosts will successfully kick off!
Unfortunately there are still missing/outdated dependencies, so the
build doesn't yet succeed. This makes it much easier to check what we're
failing on though.
I've also added the processor/arch to "Unknown X" error messages for
easier debugging.
Follow-up to #10183
Affects #5783

## Tests
Kicked off `build_release_vs.bat` on my Windows ARM machine. Observed
progress in the build process!

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 OrcaCloud sync platform and preset bundle sharing system
Introduce OrcaCloud, a cloud sync platform for user presets, alongside
a preset bundle system that enables sharing printer/filament/process
profiles as local exportable bundles or subscribed cloud bundles.
OrcaCloud platform:
- Auth to Orca Cloud
- Encrypted token storage (file-based or system keychain)
- User preset sync with
- Profile migration from default/bambu folders on first login
- Homepage integration with entrance to cloud.orcaslicer.com
Preset bundles:
- Local bundle import/export with bundle_structure.json metadata
- Subscribed cloud bundles with version-based update checking
- Thread-safe concurrent bundle access with read-write mutex
- Canonical bundle preset naming (_local/<id>/... and _subscribed/<id>/...)
- Bundle presets are read-only; grouped under subheaders in combo boxes
- PresetBundleDialog with auto-sync toggle, refresh, update notifications
- Hyperlinked bundle names to cloud bundle pages

Fix fan speed staying high
When fan speed-up time is enabled, layers can inherit a higher fan speed than intended.
If a layer ended with a role-driven fan change, the last applied fan speed
was not properly tracked. As a result, the next layer could start with an
incorrect fan state and keep the higher speed until another fan command
overrode it.
Ensure the emitted fan speed is always tracked correctly, including when
flushing buffered commands at the end of a layer.
The X1C's RTSPS server emits unreliable decode timestamps (wildly
non-monotonic jumps, sometimes none at all). The previous AVC1 path in
gstbambusrc forwarded sample.decode_time straight into the pipeline as
DTS, which made GStreamer's basesink wait for the pipeline clock to
catch up with timestamps that were thousands of seconds in the future,
freezing playback after a few seconds of streaming.
Replace the trust-the-printer approach with synthesized monotonic
timestamps, the same trick mpv uses when it reports "No video PTS!
Making something up.":
* stamp PTS = sttime + frame_count * period
* adapt period to the real inter-arrival rate via EWMA (the announced
frame_rate is also unreliable -- X1C reports 30 fps but delivers
~28 fps), keeping the synthesized timeline aligned with arrival
* apply a 100 ms lead so the sink has a small jitter buffer to
absorb the bursty 2-3-frames-then-gap delivery pattern of the
Bambu tunnel
* re-anchor only on large divergence (printer pause, stream resume,
fps change) instead of every few seconds
The MJPEG path was already wall-clock-stamping arrivals; this unifies
both formats on the same scheme.
Confirmed on an X1C in LAN-only mode (RTSPS) on Fedora 43; not tested
on P1/A1 hardware. Other Bambu printers share the same Linux source
and could see the same fix where their decode timestamps or announced
framerate are similarly unreliable, but that has not been verified.
No effect on Windows/macOS -- gstbambusrc.c is Linux-only. Trade-off
is +100 ms of camera-view latency, which is invisible for a print-
monitor use case.

* 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.
* Fix: Address code review comments
- Fix memory allocation for extrusion layers deep copy
- Remove unused variable in GLCanvas3D
- Fix string formatting crash risk in NotificationManager
- Remove dead code in Plater
