* 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.

Update Brim.cpp
* Remove multimaterial first-layer check for brims
Stop detecting extruders used on the first layer and remove the is_multimaterial_first_layer guard. Simplify can_combine_brims to only consider combine_brims and whether printing is ByObject, allowing brims to be combined across extruders unless printing by object or combine_brims is disabled. Cleans up unused code and simplifies brim-generation conditions.
* Remove material specification from unified brim comment
* Update PrintConfig.cpp
Config key rename (breaking for saved profiles — call out in PR):
ixex_carriage_width_x/y → ixex_nozzle_clearance_x/y
Labels updated to "Nozzle Clearance X/Y" with consistent tooltips
describing the measurement as nozzle-to-collision-side-edge distance.
Strip math fix:
Previously halved the clearance value (× 0.5) under the assumption
the nozzle was centered in the carriage. The measurement is now the
literal nozzle-to-edge distance, so the × 0.5 factor is removed.
The collision strip width now equals the configured value directly.
Carriage box visualization (GCodeViewer):
- Add per-carriage box_offset_x/y so the nozzle marker sits at the
physically correct edge of the footprint box rather than centered.
- X: zone-based by default (nozzle at inner edge facing bed center).
Copy secondaries inherit the primary's X orientation (same movement
direction). Mirror secondaries use the collision-side edge.
- Y: always row-based regardless of copy/mirror mode. Gantry is always
behind the nozzle (high-Y); front-row primaries with a back-row
secondary override to place nozzle at the low-Y edge.
- Fix stale mesh bug: GLModel::init_from() is a no-op when already
initialized. Call reset() before init_from() so mesh rebuilds
correctly when nozzle clearance values change in config.
- Remove m_ixex_toolhead_box_dims (was the now-unnecessary cache key).

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
# Description
This pull request fixes the bug where Orca Slicer enters an infinite
loop when a density of zero is introduced for the top layer solid infill

Note: For bottom solid infill, this is not a problem because the minimum
density is 10%.
Makes sure all non-bbl printers go through the same filament reordering
code so custom filament sequence is properly handled, while skipping the
filament grouping part by mapping all filaments to group 0.
This is the same method used by BBL printer to calculate the optimal
filament grouping so should be robust.
Fix#12449Fix#12766
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.
Add a guard that skips creating fill params for top surfaces when the configured density is less than or equal to zero. This avoids generating surface fills for zero/negative densities and prevents unnecessary processing or potential errors when top surface density is disabled.
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.
