# Description
This PR enhances the GCodeProcessor's time estimation by incorporating Junction Deviation (JD) into the jerk calculations, providing more accurate print time predictions for firmwares that use JD (like modern Marlin).
Key Changes:
- Added JD support to time estimation
- Reads machine_max_junction_deviation (machine limits) and default_junction_deviation (print profile)
- When JD is enabled (>0), replaces traditional X/Y jerk values with JD-based calculation:
$Jerk = \sqrt{2.5\cdot JD \cdot acceleration }$
- Falls back to traditional jerk when JD is not used
# Test:
JD:0.0256mm Accel.: 1000 mm/s²

print_machine_envelope() used get_extruder_id(extruder_id)*2 to index
machine limit arrays that only hold [Normal, Stealth] (2 entries).
For multi-extruder setups this went out-of-bounds, causing wrong M201/M203
values in the G-code which then override the estimator's correct limits.
Same class of bug as c6d1c11ebb but on the G-code writer side.
Changes:
- Remove unused extruder_id param from print_machine_envelope()
- Use .values.front() for M201/M203, matching M204/M205 in same function
- Change get_option_value() fallback from .back() to .front() so any
future out-of-bounds index returns Normal mode instead of Stealth
The extruder_id*2 offset in get_axis_max_feedrate/get_axis_max_acceleration
was cherry-picked from BambuStudio's per-nozzle limit system, which OrcaSlicer
never ported. Without that system the limit arrays only have 2 values
([0]=Normal, [1]=Stealth), so any extruder_id > 0 or the uninitialized
value (255) would overshoot the array and fall back to values.back(),
always returning stealth-mode limits and producing incorrect time estimates.
Revert to indexing by time mode only (matching v2.3.1 behavior) and simplify
the M201/M203 handlers to write only the two mode slots they actually use.

* Port Pressure Advance visualization to libvgcode architecture
Adapt PA visualization (originally in commit e3a77259) to work with
the new libvgcode library introduced by upstream PR #10735.
Changes across the libvgcode stack:
- PathVertex: add pressure_advance field
- Types.hpp: add PressureAdvance to EViewType enum
- ViewerImpl: add ColorRange, color mapping, range updates for PA
- LibVGCodeWrapper: pass pressure_advance from MoveVertex to PathVertex
GCodeViewer UI integration:
- Add "Pressure Advance" to view type dropdown
- Add PA color range in legend (3 decimal places)
- Add PA value display in sequential view marker tooltip
- Add PA row in position properties table
The GCodeProcessor PA parsing (M900, M572, SET_PRESSURE_ADVANCE)
is preserved from the original implementation.

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.
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.

## 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 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.

# Description
Fix application freeze when Prime Tower brim is set to Auto
This PR fixes an issue where enabling Auto brim width for the Prime Tower caused the application to freeze and consume unbounded amounts of memory.
Root cause
0c5f6c9865/src/libslic3r/GCode/WipeTower2.cpp (L2036-L2039)
When Auto brim is selected, the brim width was not being computed and the raw configuration value (-1) was used directly.
This resulted in an effectively infinite loop during Prime Tower brim generation, leading to runaway memory allocation instead of a controlled failure or a crash.
Solution
The Auto brim width is now properly computed based on the Prime Tower height, matching the intended behavior and existing logic used in other slicer implementations.
* Replace spline with PchipInterpolatorHelper in flow compensator
Swapped out the tk::spline implementation for PchipInterpolatorHelper in SmallAreaInfillFlowCompensator. Updated member types and method calls to use the new interpolator for improved flow compensation modeling.
* Enforce strictly increasing flow compensation factors
Added a check to ensure that flow compensation factors in SmallAreaInfillFlowCompensator strictly increase with extrusion length, throwing an exception if this condition is not met. This improves input validation and prevents invalid compensation models.
* Add context to Small Area Flow Compensation errors
Prefixed error messages in SmallAreaInfillFlowCompensator with 'Small Area Flow Compensation' for improved clarity and debugging. Also rethrows exceptions after logging to ensure proper error propagation.
* Remove spline library from dependencies
Eliminated the spline header-only library from the project by deleting its CMake configuration and header file, and updating documentation and build scripts to remove references to spline. This streamlines the dependencies and build process.
Because total print time is typically a big floating point number and the time of trapezoid is typically a small number, summing those numbers leads to a loss in precision. Switching to doubles reduces the loss of precision.

By using Manhattan distance, a penalty function is constructed by weighting the distance from the safe position to the camera and the distance from the current position, incentivizing safe positions to move away from the camera. The isometric line of the integrated Manhattan distance changes from a circle to a trapezoidal shape, with the Euclidean distance toward the camera being half that away from the camera. This ensures that when selecting a safe position, points with the same Euclidean distance from the current position receive a smaller penalty if they are farther away from the camera.

In the safe position calculation for time-lapse photography in traditional mode of piece-by-piece printing, for parts not currently being printed, the maximum expansion radius is used for parts higher than the current layer, and half of the expansion radius is used for parts lower than the current layer height; half of the expansion radius is used for the parts themselves. This reduces unnecessary avoidance.
