07a5551dad BBS Port: Mesh Subdivision (#12150)
Ported from BBS
You can now right-click a part and choose Subdivide Part to apply Loop subdivision with multiple iterations. This is useful for models with low original mesh resolution.

> [!NOTE]
> 1. Only meshes without non-manifold edges are supported.
> 2. Color attributes will be lost after subdivision. We recommend subdividing first, then painting and applying colors.

Not perfect and it can break some features but a nice to have and we can improve it.

66e695f306 Fix issue #10971 (#12108)
Sorry had to re-create the PR as I did some chaos in my repo with CLI. xD

Fixes issue https://github.com/OrcaSlicer/OrcaSlicer/issues/10971

Description:
Fix wipe tower filament selection and clean up tool ordering. Added wipe_tower_filament handling to WipeTower2 (store config, mark non-selected tools as “soluble,” and use it in toolchange selection) and ensured the configured wipe‑tower extruder is included in the extruder list for ordering. Removed duplicated/merged tool‑ordering code (extra insert_wipe_tower_extruder definition, duplicate declaration, and redundant reorder block) so the tool order logic runs only once.

ef0bfe6197 Adds (AMS) filament sync options: Only sync color / sync all (#12169)
This PR adds a new filament sync mode setting for device-based filament synchronization.
Users can now choose between syncing both filament preset + color (current behavior) or syncing color only, so calibrated local filament profiles are preserved while still updating slot colors from the printer.
It also includes small UI improvements for the new preference entry and sync status messaging.

59ea4746b1 feat: Add File header G-code option and print_time_sec/filament_length_m placeholders (#12186)
## 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)

* Fix Linux compile (hopefully)

* Add an option to associate DRC files on Windows.

* Implement a Preferences option to set Draco position quantization bits

* Update src/slic3r/GUI/Preferences.cpp

Co-authored-by: Ian Bassi <ian.bassi@outlook.com>

* Some slight changes to ianalexis's suggestion.

* Implement a create_item_spinctrl() function for numeric inputs, and use that instead of create_item_input().

* Move "bits" to inside the spinctrl box.

* Refactor following yw4z's feedback

* Update src/slic3r/GUI/Preferences.cpp

Co-authored-by: Ian Bassi <ian.bassi@outlook.com>

6d57ada0a8 Calibs: Process layer height (#11835)
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.

45c178eb99 Fix active filament preset not matching wizard selection on first run (#12132)
* 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.

6cea172577 fix: adaptive layer height profile uses uncompensated Z height (#12080)
layer_height_profile_adaptive() was using object_print_z_height()
(shrinkage-compensated) to bound the profile, but
update_layer_height_profile() validates against
object_print_z_uncompensated_max. When shrinkage compensation is
active, the mismatch causes the adaptive profile to be silently
cleared every frame and replaced with flat layers.

Use object_print_z_uncompensated_height() instead, matching both
the validator and the existing layer_height_profile_from_ranges()
implementation which already uses the uncompensated value.

ca7f042d49 Fix aligned back seam positioning for mirrored objects (#12028)
* Fix aligned back seam positioning for mirrored objects

This change makes “Aligned back” seams behave the same on mirrored models as on normal models.
Mirroring flips the model’s surface directions, so the slicer treated the back as the front.
Now it corrects those directions when calculating seam visibility, so seams still line up on the back after mirroring.

ca543338ee Refactor: move Printer dependencies data validation from Preset to Tab (#12026)
# Description
When creating a new filament preset and setting the Printer Dependencies to "All", the preset does not save this setting. This issue only occurs on creation due to code that is meant to validate the data to prevent a case where the filament is compatible with none of the printers.

EDIT: While I considered redoing the data validation for this tab overall, I have now preserved the original purpose of the code, which is to add the current printer as a compatible printer only if:
- the base preset is a System preset
- the user has not specified any compatible printers

Notably, this seems to be the cause of #11959 

Moving the data validation from `Preset::save_current_preset` to `Tab::save_preset` allows the Preset function to be simplified through removal of the current printer parameter.

# Screenshots/Recordings/Graphs
There is no visible change on the UI.

## Tests
Tested the following combinations of filament presets:
- System->new User
- User->new User
- User->same User

Tried to set them to All, where the System->new User should be the only case where this is replaced by a default.
In any case where there are printers already set, those settings should be kept.

# Description
### `src/libslic3r/PrintApply.cpp` changes (line 318)
Change `const auto` to `const auto&` for loops (simple optimization) .


### `src/slic3r/Utils/CalibUtils.cpp` changes (lines 762, 766, 779, 783/784, 814, 816, 831, 835, 837, 1001)
Define config_pattern
`const auto& config_pattern = SuggestedConfigCalibPAPattern();` (line 762 and 814)

Replace calls of `SuggestedConfigCalibPAPattern()` with `config_pattern` (lines 766, 775, 779, 783, 784, 816, 831, 835, 837)

Change `const auto` to `const auto&` for loops (simple optimization) (lines 816, 835, 837, 1001)

*Also gets rid of the five compiler warnings out of the few hundred/thousand (when building the entire project) that warn about copying loop variables*
i.e.
```/home/neo/git/OrcaSlicer-EDIT-TEMP/src/slic3r/Utils/CalibUtils.cpp:828: note: use reference type to prevent copying
/home/neo/git/OrcaSlicer-EDIT-TEMP/src/slic3r/Utils/CalibUtils.cpp:832: warning: loop variable ‘opt’ creates a copy from type ‘const std::pair<std::__cxx11::basic_string<char>, int>’ [-Wrange-loop-construct]
  832 |     for (const auto opt : SuggestedConfigCalibPAPattern().int_pairs) { print_config.set_key_value(opt.first, new ConfigOptionInt(opt.second)); }
```
## Tests
Should have no functional difference. Contains optimizations, calibrations appear to still function well.

c1f609f27a Fix: Apply bed–filament compatibility checks to all printers (#11432)
### What was the issue?

The check that validates whether a filament is compatible with the selected build plate type was only executed for Bambu Lab printers.
Other printers skipped this entirely, even though they can also use multiple plate types with different temperature requirements.

This caused cases where:
- incompatible filament/plate combinations went unnoticed,
- users received no warning even when the bed type clearly couldn’t support the selected filament.

### What’s changed?
- The validation block extends beyond BambuLab printers.
- Now all printers get the same compatibility check:
  - if a filament requires a bed temperature not supported by the chosen plate,
  - Orca shows the same clear error message as it does for BBL printers.
- Show the selected filament preset name (alias if present) in bed/filament mismatch warnings instead of substituting the parent preset.

### Why this helps
- Consistent behavior across all printer brands.
- Prevents invalid filament/plate setups that could cause print failures.
- Makes plate presets more robust and predictable for custom and community printers.

### Notes
- No behavior changes for BBL printers — they keep the existing checks.
- Other printers now benefit from them too.
