Completes the Split-type IMEX mode plumbing started in 0bb1cef. Phase 1
landed the config option, helper, validator, and plater badge updates;
this commit lands the visualization side and the editor surface so users
can actually create and use Split modes.
Zone aggregation (PartPlate::calc_imex_zones)
- When mode_type == "split" and there's row separation between primary
and secondaries, collapse copy_cells and mirror_cells per-gantry
(each cell gets primary's column) and force has_col_sep = false.
make_boxes then takes its full-X-row branch and renders one zone
covering each non-primary gantry's full Y band, instead of per-tool
quadrants.
Ghost aggregation (PartPlate::calc_imex_ghosts)
- Pre-scan the active mode's tool list to pick a canonical head per
non-primary gantry (the tool whose physical column matches primary's;
fallback to first-seen). For Split modes, the per-head emission loop
skips non-canonical tools so each non-primary gantry gets exactly one
aggregate ghost rendered at the canonical's mirrored position.
- update_imex_ghost_transforms unaffected — it iterates the already-
filtered ghost set.
Modes editor Type column (IMEXModesCtrl in Tab.cpp)
- Each non-primary mode row gains a wxChoice dropdown selecting Copy /
Mirror / Split. Primary row gets a static "Primary" label.
- Header row picks up a "Type" column header with sized spacer that
aligns with the dropdown.
- get_mode_data() now returns a fourth tuple element (types vector).
load_from_config() reads imex_mode_types via imex_mode_type_for so
legacy presets without the new option still infer types from mode
names. on_change writes imex_mode_types back to config.
- matches_config(), snapshot_row(), row_differs_from_parent(), and
reset_row_to_parent() all extended to track type alongside name/
tools/gcode — per-row reset arrows reflect type-only changes, and
reset restores the parent's type via imex_mode_type_for fallback.
- Type-choice dropdown fires notify() on change so the dirty/save flow
catches it like any other row edit.
End-to-end: switching a row to Split type in the modes editor, then
selecting that mode on a plate, allows multicolor slicing (the gantry-
pair check is bypassed in imex_multicolor_block_reason) and the bed
visualization shows a single aggregate zone + one ghost per non-primary
gantry instead of per-tool clutter.

Some Background
Open-source slicing has always been built on a tradition of collaboration and attribution. Slic3r, created by Alessandro Ranellucci and the RepRap community, laid the foundation. PrusaSlicer by Prusa Research built on Slic3r and acknowledged that heritage. Bambu Studio in turn forked from PrusaSlicer, and SuperSlicer by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.
