Temperature emission (GCode.cpp, PrintConfig.cpp, ConfigManipulation.cpp):
- Set temperatures for all active tools in layer_change_gcode for iMEX
parallel modes (primary + secondary carriages)
- Fix filament temperature commands so Layer 1 temperatures only emit on
the first layer; subsequent layers use normal layer-change temperatures
- Remove stray temperature commands that fired outside the intended context
- Consolidate iMEX temperature handling into the second-layer transition;
clean up emission logic and naming throughout
Pre-slice warning dialogs (PartPlate.cpp/hpp, Plater.cpp):
- Collect per-plate IMEX warnings before slicing: multi-material conflict,
bed temperature mismatch between carriages (>5 °C delta), and filament
type incompatibility
- Show a dismissible Yes/No dialog from both "Slice Plate" and "Slice All"
actions; No returns to 3D view, Yes proceeds to slice
- Refresh plate thumbnails after the panel switch so previously-generated
thumbnails are not left black

In iMEX (IDEX/IQEX) parallel printing modes (copy/mirror), only the
primary extruder generates toolpaths. The firmware duplicates the
primary's movements for secondary carriages, so they don't appear in
tool_ordering.all_extruders().
This caused is_extruder_used[N] to return false for secondary tools
even though they're physically active and moving.
The fix adds logic to parse the active mode's tool assignments from
imex_mode_active_tools config and marks all assigned tools as used.
Changes:
- Added null checks and bounds validation for config options
- Skip empty tool strings to avoid unnecessary parsing
- Reordered bounds checks for defensive programming
- Added clarifying comments for exception handling
This ensures is_extruder_used[N] is true for all tools in a parallel
mode, allowing printer profiles to correctly enable heaters and
emit cleanup G-code for all active carriages.
Fixes: is_extruder_used[1] returns false in copy/mirror modes (#13086)
Related: Comment [28]/[30], Comment [18] (is_extruder_used in G-code header)
Register imex_mode (string), imex_mode_index (int), and imex_mode_gcode
(string) in OtherSlicingStatesConfigDef so they appear in the placeholder
search UI under Slicing State.
Set all three via placeholder_parser().set() before any script processing
in _do_export(). Process imex_mode_gcode first so {global} declarations
defined there flow forward into machine_start_gcode.

IMEXModesCtrl:
- Primary mode is now a non-deletable first row stored as sentinel
"primary" in imex_mode_names; older configs load cleanly
- New rows default T0 → Primary when no tool assignment is stored
- Filter "primary" from plater popup/cycle list to prevent double entry
- imex_tools_per_gantry cap raised 2 → 4
Zone sizing:
- Zone width/height now based on active tool count only; inactive tools
donate their bed share to active neighbors (fixes 4-tool layout)
- Active col/row maps (col_to_zone/row_to_zone) applied consistently
across zone fills, collision strips, and primary zone box
GCodeViewer animation:
- Mirror position formula fixed: left-of-copy reflects across copy
zone's left edge; right-of-copy reflects across right edge
(T3 was rendering on top of T1)
- strip_width/row_strip_height use active counts, matching PartPlate
Stability:
- Early return in calc_imex_zones() when tool_states is empty; prevents
OOB crash on new printer with stale process-preset mode name
- is_imex toggle in on_config_change calls refresh_imex_icons() so the
plate mode icon appears without requiring a new project
GCode:
- Remove "primary" guard so Primary mode gcode field is emitted at
start of print

* Fix crash-inconsistent draft shield
* Skip empty skirt G-code and fix skirt_done handling
Track whether a skirt was actually generated for the current print Z and avoid appending empty skirt G-code. Only pop m_skirt_done when a skirt was emitted to prevent corrupting skirt state across multiple instances per layer. Also use a temporary string (moved into the main gcode) to detect emptiness before updating state. Preserves existing first-layer clearing behavior.

Stop detecting extruders used on the first layer and remove the is_multimaterial_first_layer guard.

Introduces first-class parallel printing (copy/mirror modes) for printers
with multiple independent X-axis carriages. Branded iXex (independent X
extruder), targeting Klipper firmware with a firmware-agnostic design.
- PrintConfig: new printer options declaring iXex capability and geometry
(is_ixex, ixex_gantry_count, ixex_tools_per_gantry, carriage dims,
tool layout, and per-mode name/role/gcode arrays)
- Preset: iXex keys registered in printer and process preset option lists
- Tab: IXexModesCtrl visual grid editor in Printer preset tab; mode
dropdown in Process → Others tab; clear_pages() nulls iXex pointers to
prevent dangling-pointer crash on preset save
- PartPlate: 2D zone visualization (active/dimmed/dividers) and
placement-violation detection (has_ixex_placement_violations) that
blocks slicing when objects fall outside the primary zone
- Plater: violation detection wired into update_background_process so
the Slice button is disabled with an error notification on violation
- GCode: mode-activation G-code injected before machine_start_gcode
- GCodeViewer: multi-carriage toolhead markers in sequential preview,
filament legend annotated with active carriage count and mode name
Previously, wipe tower behavior was determined by checking if the printer
was a QIDI vendor. This introduces a configurable enum (Type 1 / Type 2)
so any printer can select its wipe tower implementation. BBL printers
remain hardcoded to Type 1. Qidi profiles default to Type 1.
When flush_multiplier is applied to flush_volumes_matrix values, the
result can be a decimal (e.g., 272 * 1.3 = 353.6). Some printer firmware
metadata parsers (notably Creality K2) crash when parsing decimal values
in flush_volumes_matrix, causing prints to get stuck at "File selected".
This fix rounds the multiplied values to integers, ensuring compatibility
with firmware that expects integer values in this field.
Fixes compatibility with Creality K2 and potentially other Klipper-based
printers that parse the CONFIG_BLOCK metadata.

The WipeTower2 code path never called construct_mesh(), leaving
wipe_tower_mesh_data as std::nullopt. GCode export then dereferenced
it unconditionally, triggering an assertion failure / crash.
Added checks in ByLayer print sequence to handle ordering for Intra-layer ordering option. Prevents new ordering setup when "As object list" is enabled.
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

## 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)

When the retraction setting is larger than the retraction during the material change, the travel triggered during the material change will make up for the retraction interpolation, but the retracted extruder head will be the wrong one. By moving the travel part in the extruder switch Gcode to after the traditional head change (where m_curr_extruder_id in writer() is updated), the old ID is avoided during travel.
