The plate's mode button showed one icon whatever the mode. It now shows the
mode the plate slices as, the one its ghosts follow. imex_mode_kind() reads it
from the heads beside the mode's primary: none is Normal, any Span head is
Custom (the multicolor modes), otherwise any Mirror head is Mirror, and heads
that all copy are Copy. One Mirror head is enough because an IQEX mirror mode
copies within the primary's gantry.
The icons are Felix14-v2's: the four kinds, each in light and dark with a hover
state, replacing the single mode icon. Two fixes to them: the light Normal
border used the dark theme's gray, and an opacity="undefined" attribute hid one
of its strokes in nanosvg. The knight outlines are drawn at 1.0 rather than
0.8, matching the other plate icons and keeping Copy and Mirror apart when
zoomed out.

* Fix debug build after qhull upgrade
We upgraded qhull from 8.0.1 to 8.0.2 in 504a5d3b70, which contains a commit qhull/qhull@16159c648c `use same CMake target name for Debug and non-Debug`, so this target name check is no longer required
* Fix issue like `IMPORTED_LOCATION not set for imported target "opencv_world" configuration "RelWithDebInfo".` when build Debug config
Seven commits: painted multi-material segmentation made deterministic, missing
includes added across src/slic3r/GUI, U1 high-flow nozzle variants, Windows
ARM64 build and HTTPS fixes, and a rule added to the wxWidgets agent skill.
Three conflicts, all include lists: upstream's include pass and ours each added
to the same lists in GCodeViewer.hpp, PartPlate.hpp and PartPlate.cpp. Resolved
as the union of both. Three includes both sides had added at different places,
which git kept twice, are kept once: Color.hpp and <set> in PartPlate.cpp,
<sstream> in Plater.cpp.

The IMEX fixtures set seven nozzles but kept multifilament_config's single
filaments x filaments flush block. get_flush_volumes_matrix splits that block
across the nozzles, leaving each with 7 values, and
ToolOrdering::reorder_extruders_for_minimum_flush_volume then reads them as a
7 x 7 matrix, past the end of the buffer. One of the affected tests segfaulted
on Windows x64; ASan reproduces the overflow in that test on Linux, where it
passed only by luck.
The fixtures now repeat the block once per nozzle, as the GUI does, and size
flush_multiplier to match, since append_full_config takes the nozzle count from
it. The helper is shared in test_helpers.

* Keep User Preset Values on Extruder Variants They Don't List
A user preset stores the variant list its parent had when it was saved.
When the parent later gains variants, update_diff_values_to_child_config
matched variants by name only and left the new ones at the parent's
value, so the user's settings were silently replaced there, and a
re-save wrote the system values into the user's file.
An unmatched parent variant now takes the child's first variant of the
same extruder, the rule slicing already uses in get_config_index_base.
A child without a variant list covers the parent's first extruder. The
name match also no longer indexes the child's extruder ids when it has
none.
* Share One Variant Column Rule Between Slicing, User Presets and Projects
Three places chose which variant column a value comes from, each with
its own copy of "the same variant and owner, else the owner's first
column": get_config_index_base when slicing, the user preset merge in
update_diff_values_to_child_config, and normalize_filament_values_to_variants
for projects and the CLI.
find_variant_column now holds that rule and map_variant_columns applies
it to a variant list, so a change to how missing variants are filled
reaches all three. Each caller keeps its own copy step. There is no
behaviour change: G-code is identical before and after. The one
relaxation is that get_config_index_base no longer reads past a short
id list when its two lists differ in length, which its assert already
rules out.

The ARM64 jobs pinned CMake 3.31 because CMake 4 dropped pre-3.5 policy
compatibility and its ARMASM support broke Boost.Context. Both are
handled now. deps/CMakeLists.txt sets CMAKE_POLICY_VERSION_MINIMUM on
CMake 4, and Boost.Context uses the winfib implementation on ARM64, so
nothing assembles with armasm.
CMake 3.31 also predates VS 2026. Its InstallRequiredSystemLibraries
treats the v145 toolset as v143, searches only the VS 2017-2022 install
directories and finds no runtime, so the ARM64 installer ships without
msvcp140.dll and vcruntime140.dll. CMake 4.2 and newer find the VC145
redistributable.
get-cmake also installs Ninja, so the ARM64 jobs now use its latest
release instead of the one already on the runner, as x64 does.
The install now fails when InstallRequiredSystemLibraries returns no
msvcp140.dll or vcruntime140.dll, after a configure warning naming the
CMake and MSVC versions. A CMake that predates the Visual Studio in use,
on a developer machine or after the next runner image update, then
stops the installer build instead of shipping one that cannot start.
The build_win.bat prerequisite installer drops its matching 3.31.8 pin.
This is the bulk of the profile changes for U1 that led to the cooling
catiant connection.
The ugly end gcode is used by the printer's UI to complain if normal
nozzle is installed but the file was sliced for highflow.

* Make Painted Multi-Material Slicing Deterministic
Painted (multi-material) models sliced to slightly different G-code on
every run: ±1 µm wall coordinates and reordered islands. Hashing each stage
of the segmentation across runs showed the projected painted lines and the
per-layer Voronoi segmentation were stable; the raw top/bottom projections
from slice_mesh_slabs() were not. Three causes, all thread-order dependent:
- slice_slabs_make_lines() appends each slab's intersection lines from a
parallel facet loop and never restored a canonical order, so the loop
start vertices and polygon order from make_slab_loops() depended on
scheduling. Sort every slab's lines with the same key slice_make_lines()
already uses.
- segmentation_top_and_bottom_layers() wrote a layer's shell projections
into neighbouring layers' vectors from the parallel loop, relying on a
parity double-buffer that assumes TBB ranges are exactly one group wide
and aligned, which blocked_range does not guarantee; two threads could
append to the same vector. Each source layer now records its projections
in its own slot and they are gathered per target layer in source order.
- The painted-line sort in post_process_painted_lines() was not a total
order: projections of one span from facets of different colours tied on
every key and the first one won the span. Colour and end points now break
the tie.
Three multi-threaded runs of each painted fixture now give one G-code;
unpainted output is unchanged.
* Test That Slab Slicing Does Not Depend on the Thread Schedule
Projects a dense, tilted sphere with slice_mesh_slabs() on one thread and
then three times multi-threaded, and requires the polygons to match exactly,
vertex order included. Fails without the canonical line sort, passes with it.
A tilted layer runs from the belt to the top of the part, so a wall loop
that starts above the belt still passes along it. Tagging only the path's
first point left such loops out of the band entirely; the band is now
evaluated at each segment, with the tag capped where the fan stops
depending on it.
The clearance test needs the relative-E reset in its layer change G-code to
get past validate()'s other checks, and now asserts the height message. The
fan band test counts cycles rather than commands: the band is decided per
path start, so a cube cycles the fan far less often than a benchy.
* Add Missing Includes Across src/slic3r/GUI
Every GUI source and header now directly includes the headers declaring what it uses, rather than relying on the precompiled header or transitive includes. Generated with clang-tidy misc-include-cleaner, plus one hand edit making CalibrationPanel.hpp self-contained.
* Drop the OS-Specific Includes Added Outside Their Platform Guards
GLib, GTK, D-Bus and POSIX headers are only used inside platform #if blocks, which already include them. Added unconditionally at the top of the file they broke the Windows build.
* Add the clang-tidy Configuration That Generated These Includes
Only misc-include-cleaner's missing-include check, with the headers it must never suggest: per-platform, internal and OS-specific ones that would break other platforms or are not meant to be included directly.
* Match Windows Paths in the clang-tidy Ignore List
Header paths use backslashes on Windows, so every / in a pattern is now [/\\]. The Windows SDK headers are ignored alongside the other OS-specific ones, and the list is one pattern per line. Suggested by @raistlin7447 from a Windows clang-cl run.
Covers the case from Hanif Koh's review of #14394 (belt raft layers below
the object with no lower bound), which the negative-Z bottom layer fix in
layer_initialize() addresses.
With a first layer of about 0.28 mm or more at 45 degrees (or a shallower
belt) the brim band is wider than one bead and its lines go on the nominal
lattice. A lattice line could land where the belt is almost at the band's
print_z; its flow was clamped to half a layer while the nozzle sat nearly on
the belt. Such a line now moves uphill to the 0.75 fraction the single-line
case uses, and a line that lands on the previous one is skipped.
Ported from the Unlayered fork (patch 0007 of its belt port series, found
there by fuzzing first layer heights). The fork's companion fix, restricting
the brim filament to those the writer was handed (0008), is not needed here:
ToolOrdering registers the brim filament on every band's layer, so the writer
always has it. A test pins that with every object a flush target.
EXCLUDE_OBJECT_DEFINE keeps plate coordinates on a belt printer: the frame
after the slicing rotation is undone and before the G-code axis remap and
machine-frame shear, which is where the object stands on the belt.
Raised in Hanif Koh's review of #14394.
The purge tower is a model object the GUI creates and sizes, and libslic3r
only purges into one that exists. A multi-filament belt project sliced from
the CLI without it changed filament with nowhere to purge, silently.
Raised in Hanif Koh's review of #14394.
The cooling buffer's band pass rebuilt positions from the layer's G-code
and tested them against the first-layer plane. The G-code is in machine
coordinates and the plane is in slicing coordinates, so on the shipped
profiles the nearest move was over 100 mm from a 0.2 mm band and the pass
never changed the fan. GCode::_extrude() already knows each path's height
above the belt, so it now tags the band changes and the buffer applies and
strips the tags.
The pass also took the S of every M106 as the part fan, whatever its P
index, and stored that 0..255 value where a percentage was expected (an
auxiliary fan line came back as M106 S651); it now uses FanMover's parser,
which ignores other fans, and converts to percent. It no longer overwrites
the layer's intended speed, only the fan's actual state.
Raised in Hanif Koh's review of #14394.
belt_brim_instances_compatible() runs while the slicing parameters can be
stale, like the rest of the brim predicates, which read the print config.
Raised in Hanif Koh's review of #14394.
Apron bands looked up their filament and nozzle config slot with a running
counter, while object layers use Layer::id(), so band N read the map of
object layer N. They precede layer 0 and now use its assignment.
Raised in Hanif Koh's review of #14394.
The mesh transform is a rotation and an axis permutation, so its
determinant is always 1; rebuilding the forward transform on every
extrusion to divide the flow by it changed nothing.
Raised in Hanif Koh's review of #14394.
enable_prime_tower stays on for any multi-filament project, but a belt
printer never prints the classic tower and the belt purge prism is an
ordinary object that never takes a brim, so every brim on a multi-filament
belt print was refused for nothing.
Raised in Hanif Koh's review of #14394.
validate() skipped the build-volume height check whenever the machine-frame
transform was active, which is every shipped belt profile, so a 400 mm
object passed on a 300 mm printable_height. The transform only changes how
the height is written to G-code; the clearance check from f682ab5cd3
applies regardless.
Raised in Hanif Koh's review of #14394.
Drops the [BELT-DEBUG], [BELTRACE], [BELT-CALIB] and [BELT-PREVIEW] log
lines, the SLIC3R_BELT_DIAGNOSTIC_LOG blocks, and the counters and
temporaries that existed only to feed them. Six of the purge tower lines
logged at warning level, which is Orca's default, on every plan. Raised in
Hanif Koh's review of #14394.
preslice_remap_*, preslice_remap_global and gcode_remap_* describe the
printer's kinematics and are set once by its profile. A wrong value sends
the gantry outside the machine (a user preset with the pre-slice remap in
place of the G-code remap emitted gantry moves to Y=646 mm), so they are no
longer offered in Expert mode.
On a belt printer a lift is a move along the belt axis (0.4 mm / sin 45 =
0.57 mm of belt travel out and back on every hop), not a lift away from the
part. The three belt printer bases now ship z_hop 0, the IR3 V2 leaf no
longer restates 0.4, and the BabyBelt Pro and IR3 V2 filaments stop
overriding the printer with filament_z_hop 0.4. The option stays editable.
PartPlate's containment tests treat the plate as open along Y on a belt printer with
belt_printer_infinite_y, so a long part is no longer flagged outside the plate in Prepare
while the slicer and the G-code checks accept it. The check reads the printer preset
through the app object, which does not exist headlessly, so it is guarded on the plater.
The prism's generator already sets no_brim; PrintObject::has_belt_brim() now also ignores
any brim setting on the prism (belt_purge_tower_object), so a brim on the parts beside it
never blocks purging.
ToolOrdering::has_wipe_tower() reads the first layer's flag. On a belt the first layer may
be a brim apron band, which carries neither object nor support and never gets the flag, so
with a brim the purge plan returned early and nothing was purged. Scan the layers for a
change.
With top_shell_layers = 0 the `top` vector is never filled and erasing its begin() was
undefined (found by fuzzing on a painted object dropped below the plate).
The per-filament island tour was cached by island centroids only. A later layer with the
same centroids but fewer islands (thin walls, negative volumes) reused the stale visit
list, whose catch-all index pointed past the layer's islands, and extrude_perimeters read
freed memory (three fuzz crashes, planar and belt). The per-instance island layout is part
of the cache key and the use site never indexes past the islands.
Found by fuzzing the headless slicer:
- A BBS-style 3MF without Metadata/project_settings.config segfaulted the CLI silently on
the missing printable_height option.
- A project saved with fewer filaments (or filament groups) than --load-filaments overran
the filament variant tables (segfault in the variant match) and then hit an uncaught
ConfigurationError from set_with_restore_2 (std::terminate). The tables are regenerated
for the filaments the project did not know about, the destination vectors grown first
(only from a non-empty source), the match bounded, and a failure becomes a CLI config
error.
A 3MF vertex with a nan/inf coordinate was accepted by both parsers and crashed qhull in
ModelVolume's convex hull while the file was still loading. Both vertex handlers refuse it,
and volume generation checks again whichever parser produced the geometry. The main
parser's _stop_object_xml_parser keeps a message a handler already set.
filament_minimal_purge_on_wipe_tower became variant-keyed upstream, which
invalidated the comment claiming none of full_config's keys were.
WipeTower2::extract_wipe_volumes indexes it by raw filament slot. Not reachable
with shipped presets; noted rather than worked around.

ComboBox::SetLabel is overridden and writes the text control when the text
control is shown, which it is on an editable combo. Clearing the label after a
pick therefore erased the name. Removed; the label is never written on this
control.
Suggestions are also rebuilt when the list opens. Built in add_row they filtered
against only the rows that already existed, so a row was offered names the rows
below it had taken.
Drops the 1px inset on the Primary label, which matched a frame the name field
no longer has.

138 commits. The count is large because texture displacement merged with its
whole branch history behind it, going back to July, alongside config and preset
file locking across instances, a foundation for configurable printer agent
connections, and a day of smaller fixes and CI work.
Two conflicts, both the same shape: each side had appended to a sorted list and
git could not choose an order. libslic3r's CMakeLists gained InstanceLock
alongside our IMEXHelpers and IMEXZones, and the preset bundle loading test
gained an include for ParallelResolve alongside ours for IMEXHelpers. Both sides
kept, alphabetical. No logic conflicted.
Verified: 740 targets build clean under -Werror, and the Release suite passes
1740 of 1740, up from 1665 -- the 75 new cases arrived with the merge and all
pass. That mattered more than usual here, since preset loading and config
locking are both areas the IMEX preset code touches.

The name field becomes an editable ComboBox, the same pattern the sidebar uses
for parameters like sparse infill anchor length: predefined entries in a
drop-down, with the text still typeable. The mode table is authored for whatever
hardware the user has, so a closed list would be wrong -- nothing in the slicer
reads a mode's name except as the key a plate stores -- but the conventional
names are worth offering rather than leaving everyone to retype them.
What is offered follows the tool grid rather than a fixed list. Four carriages
get iq-copy and iq-mirror; multicolor needs a Span partner beside the primary
and a second gantry to copy the pair onto, so mc-copy and mc-mirror appear only
on a grid that can hold one. imex_resolve_routing() already refuses a multicolor
mode with no Span on the primary's gantry, and suggesting a name it would then
reject is worse than not suggesting it. Names a row already uses are dropped, so
the list only ever offers what is still free.
Two things about ComboBox matter when it is editable, which nothing else in the
tree does -- the other 78 call sites all pass wxCB_READONLY:
GetValue() returns the drop-down selection whenever there is one, so a name
typed after picking a suggestion would be silently discarded. Every read goes
through GetTextCtrl() instead. Field.cpp reconciles the same way for its own
open enums.
The constructor hands its value to TextInput as the LABEL -- the small
right-aligned slot a unit like "mm" occupies -- because a read-only combo hides
the text control and shows the label in its place. Left there, the name rendered
as a greyed echo beside the hint while the field itself sat empty. The combo is
built empty and the value written to the text control, and the selection handler
clears the label again afterwards, since SetSelection() writes there too.
The mode column widens to 176 to leave room for the drop-down arrow, with the
header spacer deriving from the same constant.
