External spools (virtual trays) are not AMS slots and should not count
toward the firmware's 16-material limit. Fixes blocking error when using
4 AMS units (16 slots) plus an external spool (17 total).
Fixes#12135
extrude_to_xyz() unconditionally emitted Z on every extrusion move
via emit_xyz(), even when Z hadn't changed. With ZAA enabled, this
produced ~987K redundant Z coordinates (98.2% of all Z emissions),
causing 10-20% file bloat.
Now compares quantized Z values before and after, and only emits Z
when it actually differs at export precision (0.001mm). Reduces
ZAA gcode Z emissions from 1,038,468 to 50,022 while preserving
all legitimate contouring Z changes.
The split point was being prepended (append_before) to p1 instead of
appended, causing it to be placed at the start of the segment rather
than the end. This resulted in rogue extrusion jumps (stringing)
across the model during ZAA sloped extrusions.
Also adds missing append/append_before calls in the exact-point
(index != -1) branch, which previously lost the split point entirely.
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.
* Add checks to snap wipe tower back to origin when it was loaded outside the plate boundary
* Fix Wipe Tower preview outside plate boundary and warning notification
- snaps wipe tower preview to nearest edge if it was loaded outside of plate boundary.
- Added warning notification to notify position change

## MultiPart 3MF
Didint change them, too much trouble for small changes.
## 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.

## 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)

Closes#11726
# Description
Removed hardcoded 0.2mm layer height.
Now it will stay in with the user process.
Also corrected several config assignments to use print_config instead of obj->config for consistency.
## Note
Didn't change PA PATTERN because i don't know if it may impact the calibration results for this specific test.
Toolchanger printers with 4 tools were incorrectly treated as dual-nozzle (IDEX-style) printers in AMS Sync. So I was locked to just tool 1/2.
Adjusted AMS Sync to use dual-nozzle logic only for true 2-nozzle setups (nozzle_nums == 2 and filament_map in {1,2}), and route 3+ tool toolchangers through the generic mapping flow so all tool IDs are handled correctly.

# Description
Fixes the Setup Wizard getting stuck on the "Loading......" screen when
running on Wayland sessions.
**Root Cause:** When OrcaSlicer runs under XWayland (Wayland sessions
with `GDK_BACKEND=x11`), WebKit2GTK's compositing mode can fail
silently, causing the Setup Wizard WebView to freeze or render blank.
The JavaScript signal from C++ (`userguide_profile_load_finish`) either
fails to execute or its rendering result never displays, leaving users
permanently stuck.
**Solution:**
1. Set `WEBKIT_DISABLE_COMPOSITING_MODE=1` environment variable to force
software rendering for WebKit2GTK - this is the same fix used by
BambuStudio
2. Enable the 20-second timeout fallback in `load.js` so the wizard
proceeds automatically even if the C++ → JavaScript communication fails
**Files changed:**
- `src/OrcaSlicer.cpp` - Added `WEBKIT_DISABLE_COMPOSITING_MODE` env var
(4 lines)
- `resources/web/guide/0/load.js` - Enabled timeout fallback (2 lines)
# Screenshots/Recordings/Graphs
N/A - This is a Linux/Wayland-specific fix that addresses a rendering
issue. The visual result is simply that the Setup Wizard proceeds past
"Loading......" as expected.
## Tests
1. **On Wayland session (e.g., GNOME on Wayland):**
- Remove existing config (`~/.config/OrcaSlicer/`) to simulate first
launch
- Launch OrcaSlicer
- Verify Setup Wizard proceeds past "Loading......" to the actual wizard
page
2. **On X11 session:**
- Same test as above to verify no regression
3. **Verify env var is set:**
- Check that `WEBKIT_DISABLE_COMPOSITING_MODE=1` is in the process
environment on Linux builds
When running under XWayland (Wayland sessions with GDK_BACKEND=x11),
WebKit2GTK's compositing mode can fail silently, causing the Setup
Wizard WebView to freeze or render blank. This leaves users stuck on
the "Loading......" screen indefinitely.
Changes:
- Set WEBKIT_DISABLE_COMPOSITING_MODE=1 to force software rendering,
matching the fix used by BambuStudio
- Enable the 20-second timeout fallback in load.js so the wizard
proceeds even if the C++ -> JavaScript signal fails
* Fix active filament preset not matching wizard selection on first run
After completing the setup wizard with only a non-PLA filament selected
(e.g. Generic ABS), the active filament preset defaulted to Generic PLA
instead of the user's selection. This happened because load_presets()
falls back to Generic PLA when the initial printer differs from the
preferred printer, and the first_added_filament override was disabled.
Add post-load correction in apply_config() that switches the active
filament to the first compatible wizard-selected filament when the
current active filament is not in the wizard selection. Also fix the
guide JS (22.js, 23.js) to use the filalist attribute for building
the filament array, and add platform-specific build test commands to
CLAUDE.md.
* Replace @System filaments with vendor-specific overrides in wizard
When the wizard selects a generic filament like "Generic ABS @System",
check if a vendor-specific override exists (e.g. BBL "Generic ABS")
and use that instead. This ensures printer-tuned profiles are preferred,
preventing load_installed_filaments from adding unwanted BBL defaults.
When printers from the default bundle are also selected, both variants
are kept since those printers need the @System version.
Also adds diagnostic logging for filament loading in LoadProfileFamily.
* Guard against persisting presets for Default Printer and fix filament override logic
Prevent export_selections from saving stale preset settings for the
built-in "Default Printer" placeholder, which is only the initial state
before a real printer is loaded. Also require a non-default vendor printer
to be selected before replacing @System filaments with vendor-specific
overrides in the wizard, avoiding incorrect filament substitution when
only the default bundle is present.
