build: clear 54 dead private fields
54 of the 161 -Wunused-private-field warnings, across 31 files. These are
the ones needing no judgment. Each member is declared once and appears
nowhere else in src/, counting the .mm and .c sources as well as .cpp and
.hpp, so nothing writes them and nothing reads them. Every removal is a
whole line, and no declaration shares a line with another member.
The remaining 107 are left alone. Those members are mentioned elsewhere,
usually assigned and never read, where the fix might be deleting the
member or might be restoring a read that went missing.
These dialogs treated a filament with no compatible_printers as compatible with
nothing, while the rest of the app treats it as compatible with everything, so
the entire Orca Filament Library was missing from the AMS material and
calibration filament lists. They now resolve compatibility the same way the
plater does, and a vendor profile still supersedes the library generic of the
same name.
* build: remove std::move that blocks copy elision
std::move wrapped around a temporary, or around a local being returned,
stops the compiler constructing it in place. Each edit is the fix clang
suggests, which is to delete the std::move call and keep its argument.
Three of the 39 sites save a move, the two return std::move(local) in
Print.cpp and TreeSupport.cpp:2749. The rest are equivalent either way
and match how the codebase already writes this elsewhere.
Clears 39 -Wpessimizing-move warnings.
* build: drop null checks on references and this
A reference cannot be bound to null and this cannot be null, so the
compiler folds these conditions to true and drops the guard. Seven are
if (&bitmap && bitmap.IsOk()), where IsOk() already does the work; two
test this directly. The guarded code runs either way, so removing the
dead operand changes nothing.
Clears 11 -Wundefined-bool-conversion warnings.
Validate mixed-filament definitions during the published material pass: definitions whose components reference slots that do not exist or hold other mixed filaments, or that carry fewer than two components, are reported through the shared skipped_keys channel instead of shipping a mix the GUI integrity check would only flag later.
Fix the slot-limit exhaustion report being silently dropped: it wrote to published_config->skipped_keys, which the pass's final move-assignment from the local vector clobbers. All rejections now go through the local.
Remove the unreachable persist branch from add_detached_preset: no caller passes save_to_project=false, so the parameter is gone and the copy is always project-embedded.
Tests: cover the exhaustion path, the new definition validation, the identity-tier matching matrix (including substitute reporting), the structural-key denylist, whole-vector size-mismatch skips, relocation payload degradation, the "(Published 2)" uniquify chain, mixed blend colours staying out of shared preset configs, and duplicate-slot last-wins. Also fix the legacy-3mf scenario passing vacuously behind an if-guarded assertion. All existing published/3mf tests pass unchanged.
- Publish mixed-filament slots as whole units: serialize the filament_mixed_* definition into project_config on import, grow the receiver's parallel arrays in lockstep, and report unappliable definitions as skipped instead of dropping them silently
- Per-extruder printer selection: one inner tab per extruder, rows keyed by full "#N" ids; single-extruder receivers collapse variants onto their slot (first applied, rest skipped), multi-extruder receivers override element-wise
- New per-slot "Enable" toggle gating what gets published; enabling a mix auto-enables + Full Publishes its components
- Mixed page previews: fixed-size ratio bar, ternary triangle (3 components) and Material Ratio vs Model Height graph (gradients), always visible regardless of Enable
- Tab strip shows full swatch compositions with adjustable spacing; barycentric helpers shared via FilamentBitmapUtils
* Keep mixed-color filaments intact when the extruder count changes
The extruder-count spinner resized the filament arrays in bulk at the tail,
which is where mixed-color slots live, so a new filament landed behind the
mix and the sidebar skipped a slot number. It now adds and removes one slot
at a time through the same calls the sidebar's +/- buttons use, so a new
slot opens ahead of the mixed tail and a removal renumbers object filament
ids, painted facets, custom g-code and mixed components rather than
clamping them away.
Drops the vector overload of set_num_filaments(), which this leaves without
callers.
Update perimeter traversal to pass each extrusion's closed/open state into `apply_fuzzy_skin`. This lets fuzzy skin logic distinguish contours from closed loops when processing perimeters.

* Fix contour cleanup across coplanar triangles
Avoid generic collinear simplification after slicing. Skip only junctions created by shared edges between coplanar faces so contours stay stable without altering shallow geometry.

* Skip straight-run splits in corner smoothing
Teach `CornerSmoother` to treat vertices that only continue a straight segment as part of the same leg instead of rounding them as corners. The smoother now keeps a three-point window so it can emit a corner only once both adjoining legs are known, which avoids unnecessary corner processing while preserving real turns such as hairpins.
* Add regression test for split-leg smoothing
Adds a FillCornerSmoothing regression test covering polylines with an extra collinear vertex in a straight run. The test ensures corner smoothing treats split and unsplit geometry identically, preventing inconsistent rounding radii in triangular/grid infill paths.

* chore: mark every declaration that overrides a base virtual
clang-cl reports 42 member functions across 28 files that override a
base virtual without being marked `override`, inside classes that
already mark their other overrides. That is every occurrence of
-Winconsistent-missing-override in the tree, so the category drops to
zero and -Werror=inconsistent-missing-override becomes available as a
guard against it coming back.
Behaviour is unchanged. Each keyword goes only where clang had already
resolved the declaration to a base virtual, so it records what the
compiler already worked out and cannot affect overload resolution or
dispatch. If any of these signatures had not really overridden a base
method, the build would have failed rather than warned.
Where a declaration already carried `virtual` it is left alone and the
keyword appended, matching the surrounding declarations. Plain
`override` is used rather than the wxWidgets `wxOVERRIDE` macro, which
wx/defs.h defines as `override` beneath a comment marking it obsolete,
and which the rest of src/slic3r already avoids by 1742 occurrences to
113.
A full clang-cl build takes -Winconsistent-missing-override from 1,146
warning lines to 0. Those 42 declarations produce that many lines
because a header is re-diagnosed in every translation unit that
includes it. CalibrationWizardStartPage.hpp alone accounts for 336 of
them from 4 declarations.
* chore: drop unused lambda captures in GUI/Widgets
clang-cl reports 10 lambda captures in src/slic3r/GUI/Widgets that are
never read. Removing them changes nothing at runtime.
Every capture removed is `this` or a raw pointer. clang does not report
a capture whose type has a non-trivial destructor, since such a capture
can be held purely for its effect on an object's lifetime, so nothing
that owns or extends a lifetime is touched. The std::weak_ptr captured
beside the removed `this` in MultiNozzleSync.cpp stays.
This clears the category in GUI/Widgets only. A full clang-cl build
takes -Wunused-lambda-capture from 312 warning lines to 302, leaving
235 sites in other directories for a follow-up.
Introduced a shared `colinear_vertex_tolerance()` helper in `ExtrusionLine.hpp` and updated both simplify paths (`ExtrusionLine.cpp` and `WallToolPaths.cpp`) to use it instead of duplicated hardcoded `0.005` scaled thresholds. This keeps the near-colinear early-out tied to `SCALED_EPSILON` (rounding-noise scale) and avoids unintended curve decimation from larger tolerances, while documenting the geometric impact in code.
