The startup prompt no longer depends on the version the previous run
recorded: whoever still has user filament presets that lost printers is
asked, including users already on a 2.5.0 nightly or alpha. Answering No
asks again at the next start; "Don't remind me again" stops it.
Migration takes the user presets lock once, around the backup and every
file write, instead of once per preset. A lock another instance holds is
reported once ("another OrcaSlicer instance is saving presets") with
nothing written, rather than as one failed preset after another once the
lock's cool-down kicks in. Detection records each preset's file and the
list it will get, so the writes need no collection lock while the user
presets lock is held, the order InstanceLock requires; the loaded presets
are updated afterwards.
The texture-displacement gizmo pushes pane state to the UV editor from the
preview rebuild that runs on every frame of a slider drag. Tile size is the
only one of the layer card's sliders whose value appears in that pane state,
so dragging it changes the "N.N mm tile" label, the panel relays out, and the
UV canvas receives a synchronous wxEVT_SIZE. Its on_size() flushes a paint
with Update(), and render() then makes the app's single shared wxGLContext
current on the UV drawable in the middle of the 3D canvas's frame.
On X11/GLX that out-of-turn context activation is fatal: the drawable the
3D canvas later swaps no longer belongs to the current context, the server
returns BadMatch, and GDK turns the unhandled X error into g_error(). EGL on
Wayland reports only a status, so the same theft silently corrupts the frame
instead of aborting - which is why the guard is not conditioned on the
display backend.
Add GLCanvas3D::is_frame_in_progress(), backed by a counter that
_render_frame() maintains through its existing scope guard, and let the UV
canvas skip the synchronous paint while a frame is on the stack, re-queueing
it with Refresh() so nothing is dropped. Rebind the context with
_set_current() before SwapBuffers() as well, so a surface that steals it by
some other route - a modal GL dialog a gizmo opens from its panel - cannot
turn the swap into the same fatal error.
Only presets that still name their parent as 2.4.2 did and have no printer
list of their own are offered, and a preset changed after it was found is
left alone. The startup prompt appears once, after upgrading from 2.4.2 or
earlier, as a standard dialog that keeps "Don't remind me again"; Help >
Migrate Filament Presets is unchanged. Migrating no longer overwrites an
unsaved printer-list edit or marks the project modified.
The cloud upload sent only the keys that differ from the parent, so a
variant layout equal to the parent's was left out. On download the
loader sized every per-variant value by the missing layout, cut it to
one value and kept the parent's values for the other nozzles and nozzle
volume types. On dual-nozzle printers the right nozzle's settings
silently reverted to the parent's after a sync.
Upload the variant layout always, as the local save already does, and
read copies stored without it against the parent's layout when they
carry one value per parent variant.
Opened or drag-dropped G-code files ignored `; MANUAL_TOOL_CHANGE` comments, so the preview showed every move on the first filament. Only `apply_config(const PrintConfig&)` read `manual_filament_change`, and loading a file goes through `apply_config(const DynamicPrintConfig&)`. Read the option there too, initialize the flag to false, and add a regression test.
Debug builds asserted on startup because these calls raise GL errors on a core-profile context. Both draws already use shaders, so removing the calls changes nothing on compatibility contexts.
* Add CGAL-based mesh repair, drop Netfabb remnants
Add repair_mesh() in MeshRepair.cpp, a CGAL-based repair that replaces MeshBoolean::cgal::repair(). It welds cracks, cancels coincident triangles, fixes orientation, fills holes (including planar annular regions), removes local self-intersections, and unites crossing shells with libigl's exact boolean while following the nonzero winding rule used by slicing.
FixModelByCgal now repairs each volume in place without splitting it into parts, and reports whether the mesh was modified so unchanged meshes keep their painting and ids. The texture import repair prompt no longer depends on the Windows SDK, and the FIX_THROUGH_CGAL_ALWAYS conditionals are removed. The commented-out Netfabb/WIN10SDK build code is deleted.
libslic3r_cgal now builds with CGAL_LINKED_WITH_TBB and links TBB. Add docs/HLSD/mesh-repair.md and unit tests in test_mesh_repair.cpp.
* Parallelize repair while preserving separate shells
Repair connected mesh units and shells independently in parallel, keep crossing shells separate, and limit self-intersection remeshing to local defects. Update mesh-repair documentation and tests for the revised behavior.
* Make mesh repair deterministic and report its progress
Flags written from parallel loops were std::vector<bool>, whose neighbouring
bits share a word, so shells could be kept or dropped at random; they are now
std::vector<char>. Holes of up to 100 edges are filled with the search over all
triangles: the search restricted to a 3D Delaunay triangulation picks between
equally good fills differently from run to run.
Shells of fewer than four faces are dropped, as the volumes of two triangles
back to back need not cancel exactly, and a shell that self-intersection removal
changed is split again so the pieces it cut off are dropped too.
repair_mesh() takes a progress callback in place of the cancel callback, and
Fix Model reports each stage. The object's bounding box is now invalidated even
when a cancel or an error stops the repair after some volumes were replaced.
The edge-use sort, union-find and box-overlap code shared by several stages is
factored out, the topology analysed for welding is reused to build the work
units, the orientation pass checks only the edges it cut, and the output is
written from the shells without joining them first.
* Fix Split to parts crashing on flat pieces and staying offered after a repair
ModelVolume::split() added every piece to the object and then deleted the
pieces without a convex hull. When the first piece was flat, as often in a
triangle soup, that deleted the volume being split while split() and its
caller kept using it. A part made only of flat pieces lost all its volumes,
and a soup added thousands of pieces, saving a backup of the object for each
one it deleted. Pieces without a convex hull are now dropped before any joins
the object, the volume being split keeps the first remaining piece, and a part
with no solid piece is left whole. Other parts of the object without a convex
hull are no longer deleted as a side effect.
ModelVolume caches whether its mesh can be split, and set_mesh() kept the
cached value, so after Fix Model, Simplify or Emboss replaced a mesh, Split to
parts could still be offered for a single piece. set_mesh() and reset_mesh()
now clear the cache.
* Import STEP surface models with Split compound enabled
Splitting a compound kept only its solids, so a surface model, which OCCT
reads as a compound of loose faces, gave nothing to mesh and the import failed
with "Meshing of a model file failed or no valid shape". Each shell outside a
solid now becomes a part too, and loose faces stay together as one part, as
they do without splitting.
* Add Fix All for plates and re-enable --repair on the command line
ModelVolume::repair() applies repair_mesh() to a part and replaces the mesh
only when the repair changed it. Fix Model, the new Fix All and Fix All Plates
items of the plate context menu, and the command line's --repair option, which
had been commented out since the Win10 SDK repair was dropped, all use it.
With Keep painted feature after mesh change off, Fix Model cleared the painting
of every part of an object before repairing. Now only a part whose mesh changes
loses its painting, so fixing a whole project does not wipe it. The
notification counts the models that needed no repair instead of listing them as
repaired, and objects that did not change are not refreshed.
A filament_start_gcode list shorter than the filament count made the Bambu start-of-export path throw std::out_of_range. Use get_at() like the other filament_start_gcode reads, and add a regression test.
stapler fetches the notarization ticket from Apple's CloudKit server,
and a dropped connection there (NSURLError -1005, exit 68) failed the
whole macOS universal job twice on 2026-10-12, after notarization had
already been accepted. Rerunning the job passed, but repeats the full
build and both notarizations.
Wrap both stapler calls in the existing retry helper already used for
hdiutil in this step.
GLGizmosManager can be called while its gizmo list is empty, either at startup before the canvas has loaded the gizmos or after their init() failed. reset_all_states(), open_gizmo(), open_gizmo_by_shortcut() and activate_gizmo() now return early in that case. This fixes a Debug-build assert when a new project resets the gizmos at startup, and an out-of-bounds read in release builds when a gizmo shortcut key is pressed after gizmo init failed. activate_gizmo(Undefined) still returns true, since no gizmo is open. The reset_all_states() guard was first proposed in #16074 by kenrap.

The reason recorded for CLI_NO_SUITABLE_OBJECTS (-50) assumed a 3mf being uploaded. The CLI also slices STL, OBJ and STEP input, so the reason now states what both -50 sites check: the plate is empty, or no object on it is both printable and fully inside the print volume. The exit code is unchanged.
Adds tests/cli/test_cli_no_suitable_objects.sh.
Pop the FramePadding style var before end() in the move and rotate gizmo windows. It was pushed inside the window and popped after End(), which failed ImGui's style stack check in Debug builds.
The CLI's arrange no longer rotates objects unless --allow-rotations is passed, which matches the GUI's default. STL, OBJ and STEP inputs are arranged even without --arrange, so a part that only fits the bed when rotated now exits with -50 unless --allow-rotations is given. The CLI prints that reason to stderr.
FanMover could split a move inside change_filament_gcode to place a delayed fan command. It computed the split point from the last position the G-code set, but on Bambu printers the firmware moves the head during the T command, so the inserted waypoint sent the head to a spot the template never visits (#15789).
Both toolchange paths, set_extruder() and the Type1 append_tcr(), now wrap the template output in ;_FAN_MOVER_SKIP_START/END tags when fan speed-up or kick-start is on. FanMover keeps fan commands inside them where they are and drops the tags from the output. multifilament_config() also sizes the per-filament options that the wipe tower reads by index.
This fixes the H2C start G-code template by commenting the two
`========== record data ==========` separator lines.
Those lines are currently emitted as raw text inside
`machine_start_gcode`. Since they are not comments or G-code commands,
they can make the generated start sequence invalid or firmware-dependent
when the template is used. The fix preserves the separators as comments.
Fixes#16218.
Validation:
- Parsed the modified JSON profile with Python `json.loads`.
- Checked both `record data` separator lines now start with `;` after
unescaping the G-code string.
# Description
Re-slicing no longer leaks layers in two places. Tree supports dropped
the support layers above the topmost overhang without freeing them. And
an object that had sliced itself, then became identical to another
object (for example a copy whose original lost a per-object setting or
modifier), leaked its own layers when it switched to sharing that
object's slices; it now frees them once it takes the shared layers over.
If slicing is cancelled before that point, they still leak, as before.
Tree support also stops copying its collision and avoidance areas on
every lookup, and releases its working cache once supports are generated
instead of keeping it until the next slice. Elephant-foot compensation
now uses each object's own slice closing radius, where the first object
sliced in a session used to fix the value for every later slice.
Slicing output changes only on layers with more than one region printed
with elephant-foot compensation and no raft, and only where an object's
slice closing radius differs from the value the session had fixed.

# Description
Fixes highlights in the texture displacement gizmo that stayed on screen
after the state behind them changed, or were drawn where they could not
be seen. Erase whole model, Select whole model and Capture current view
update the paint highlight at once instead of on the next right-click. A
stroke released outside the 3D view ends on the next mouse move, in
every paint gizmo, rather than leaving the brush stuck in its pressed
colour. The layer textures stop showing an image that has been replaced.
Selecting islands in the UV editor switches a Normal view to Fast, where
their highlight is visible instead of buried under the displaced relief,
and Normal comes back once no island is selected unless another view was
picked in the meantime.
No change to slicing output; the changes are confined to the paint
gizmos and the UV editor.

The island highlight was hidden under the Normal view's relief. Normal comes back once no island is selected, unless another view was picked in the meantime.
The segment draw switched to an element buffer of 8-bit indices. GCN 1/2
GPUs cannot read 8-bit indices in hardware, so the driver converts them,
and on a Mac Pro 2013 FirePro under Windows Boot Camp the toolpaths come
out as scattered spikes. 16-bit indices are supported everywhere and keep
the eight shader runs per segment.
Erase whole model, Select whole model and Capture current view update the
highlight at once. A stroke released outside the 3D view ends on the next mouse
move, in every paint gizmo, instead of leaving the brush in its pressed colour.
The layer textures no longer show an image that was replaced.
* Wait for the PR's Deps Cache in clang-tidy When deps/ Changes
* Fail the clang-tidy Deps Wait When Listing Caches Keeps Failing
* Wait for Deps Through ci_deps_cache.sh in clang-tidy
Reuse the macOS deps wait for Linux: the job names, workflow and cache
ref are passed in, and a new 'own' mode waits for the PR's own build
when it changes deps/. A PR that keeps deps/ now waits for a running base
build with the same deps, and warns when it falls back to older ones. The
wait ends as soon as the deps job fails.
Every slider in the texture displacement panel can now be given an exact
number, either by Ctrl+clicking the track or via a small edit icon at
its right end. Both routes reuse ImGui's own temp-input mode.
Each slider also gets a tooltip with its description and its range, and
the panel's `?` popup lists both ways in.
Draft: description to be refined.
## General
Nothing about texture displacement was written to the `.3mf`, so a
painted relief did not survive closing the project.
Everything the user set up is saved now, so a project reopens with the
relief intact and still editable.
### What is saved
- The layer stack: every per-layer setting (depth, midlevel, smoothing,
tiling, projection blend mode, colour) and the per-volume options
- Each layer's texture, as a file in the archive (why? because user
might want to move .3mf to another computer where custom textures are
missing, or he saves .3mf then deletes textures, and returns back to
.3mf)
- The painted region, one mask per layer slot
- The UV work: LSCM seams, island placement, per-vertex overrides
- Editor state: the selected layer and Standard/Pro, so the panel
reopens where it was left
### What is not saved
- The preview mesh. It is a second copy of the model in the file, for
something the app rebuilds quickly on reopen.
- Panel docked/undocked, which goes to the application config instead
## Format
- `<volume id>.json` - the layer stack and the per-volume options
- `<volume id>_<slot>.png` - each layer's texture, referenced from the
JSON through `path_in_3mf`
Paint masks ride along as one per-triangle attribute per slot
(`paint_texture_0..7`), beside
the attributes the existing paint tools already write.
## Compatibility
Both ways:
- an older build ignores what it does not know and still opens the
project, losing only the relief
- a newer build finds nothing in an older project and leaves the volume
as today.
SysInfoDialog, JumpPointSearch and WebUpdatePlugin are in no CMake list on any platform, and nothing includes ConfigExceptions.hpp, wxinit.h or Utils/Profile.hpp. MultiTaskModel holds only empty namespaces. Also drop the empty GUI_App::system_info() and comments that still mention SysInfoDialog.
TriangleMeshDeal.hpp reused Timer.hpp's guard and CloneDialog.hpp reused
SingleChoiceDialog.hpp's, so including both headers of a pair silently
dropped the second one. Use #pragma once instead.
Its inline suggestions rarely apply: clang-tidy adds a missing include
to the include block at the top of the file, which a PR seldom touches,
and GitHub only accepts review suggestions on lines in the PR's diff.
* Add a /bot fix-tidy Command That Pushes clang-tidy's Missing Includes
A maintainer comments /bot fix-tidy on a PR. A read-only job runs
scripts/run_clang_tidy.sh --fix on the PR's merge commit and returns the
patch; a second job, which never runs the PR's code, accepts it only when
it adds nothing but #include lines to C++ files the PR already changes,
then commits it on the PR head and pushes with CLANG_TIDY_BOT_TOKEN.
* Post clang-tidy's Fix as Review Suggestions Instead of Pushing It
A failed clang-tidy check now runs once more with --fix and uploads the
patch as the clang-tidy-fix artifact; the check still fails. /bot
fix-tidy downloads that patch for the PR's latest commit, checks it adds
only includes to C++ files the PR changes, and posts one review: a
one-click suggestion for each include on a line the PR's diff shows, and
the whole patch with a git apply command. Nothing is pushed and no PR
code runs in the bot, so the PR's author can run it too and no token is
needed.
* Make the clang-tidy Fix in Its Own PR-Scoped Workflow on Request
clang_tidy.yml is back to main's version. clang_tidy_fix.yml runs on
every PR push but skips its job on the first attempt; /bot fix-tidy
re-runs it, so run_clang_tidy.sh --fix runs in the PR's own context
with a read-only token and the PR's cache, never main's, and the PR's
author can ask for it. When that re-run finishes, the bot posts the
patch as review suggestions as before. When the clang-tidy step fails,
the bot also comments asking the author to run the script or the
command, edits that comment on later failures, and deletes it once the
check passes.
* Give the clang-tidy Bot Write Access to PRs It Answers
* Tell /bot fix-tidy Users How to Start a Fix Run When There Is None to Re-Run
Instead of giving user presets their parent's 2.4.2 printers in memory,
detect the user presets that inherit their parent's compatible_printers
and are missing printers from the legacy map, and offer to migrate them
at startup or from Help > Migrate Filament Presets.
Migrating first backs up the user folder to
filament_preset_migration_<datetime>_backup.zip in the configuration
folder, and migrates nothing if that fails. It then writes the printers
into each preset's compatible_printers, patching only that key so the
preset keeps the parent name it was saved with and older releases can
still resolve it. Cloud-synced presets are marked for upload.
No asks again at the next launch; "Don't remind me again" stops the
startup prompt.
A project no longer reads texture files from outside its archive, and a
malformed value or layer slot drops only the texture layers instead of
failing the whole load. Copies of an object that share a mesh keep their
own texture paint when saved, and projects without texture paint no
longer use extra memory to load.
User presets store only their diff, so they inherit the parent's
compatible_printers. Profile changes since 2.4.2 renamed and narrowed many
system filament presets, so user presets made against them disappear from
printers they were made for and the saved selection silently falls back to
another filament at startup.
orca_profile_tool.py legacy-compat writes, per current system filament
preset, the printers it covered in an older release and no longer lists,
kept only where a preset with the same filament_id still covers the printer
and they share an extruder variant. The loader gives these printers to user
presets that inherit their parent's list, without writing any file; saving
a preset detached, cloned or with its own list drops them.
# Description
With "Support multi bed types" enabled on a Qidi printer, the
first-layer bed temperature was always taken from the Smooth PEI / High
Temp Plate setting, whichever plate type was selected.
The slicer computes the right value (`first_layer_bed_temperature` in
the G-code footer follows the selected plate), but the machine start
G-code of these presets hardcoded `[hot_plate_temp_initial_layer]`:
- `fdm_qidi_x3_common` (base of X-Max 3, X-Plus 3, X-Smart 3, X-Plus 4,
Q1 Pro)
- `Qidi Q1 Pro 0.4 nozzle`
- `Qidi X-CF Pro 0.4 nozzle`
They now use `[bed_temperature_initial_layer_single]`, which follows the
selected plate type, as most other profiles do. The Qidi bundle version
is bumped to `02.04.00.17`.
With "Support multi bed types" disabled, these printers use the default
plate (Smooth PEI / High Temp Plate), so the temperature is unchanged
there.
# Screenshots/Recordings/Graphs
N/A — profile change only.
## Tests
`python3 scripts/orca_profile_tool.py check` passes.
Sliced on Qidi X-Max 3 0.4 nozzle with "Support multi bed types"
enabled, `0.20mm Standard @Qidi XMax3`, `Generic PLA @Qidi`, with a

layers).
Before, with first layer set to 50–55 °C: `M190 S54` for every plate

On Linux and macOS the app follows the system theme: at startup it
overwrites the saved dark_color_mode with the system appearance. The label
colours and the cached dark mode flag were already set from the saved value
by then, and the later "changed" check reads the mode only after the
overwrite, so it never fires. For that session every dialog that maps its
colours through UpdateDlgDarkUI keeps the old mode, e.g. white dialogs on a
dark main window after switching the desktop to dark, or on a fresh install
on a dark desktop.
Refresh the label colours and the flag when the system theme differs from
the saved mode.
# Description
## Summary:
Adds favorite filament support to the AMS material selection dropdown.
Users can now click a star icon next to a selectable filament in the AMS Materials Setting dialog to mark it as a favorite. Favorited filaments appear in a new `Favorite filaments` section at the top of the dropdown, while all compatible filaments remain available in the `All filaments` section.
This PR also adds generic right-side action icon support to Orca's custom dropdown widget:
- Adds optional action icons to `DropDown::Item`.
- Adds a new `EVT_DROPDOWN_ITEM_ACTION` event for clicks on the action icon.
- Relays the action event through `ComboBox`.
- Adds `ComboBox::RefreshDropdownIfOpen()` so callers can refresh an already-open dropdown without changing normal `ForceDropdownOpen()` behavior.
The AMS favorites implementation:
- Uses existing bundled star assets:
- `score_star_dark` for non-favorited filaments
- `score_star_light` for favorited filaments
- Stores favorite filament IDs in app config under `ams_favorite_filament_ids`.
- Stores stable filament IDs instead of display names
- Uses existing C-style string escaping helpers for persistence.
- Keeps Bambu/RFID/read-only slot behavior unchanged
No new external dependencies.
**Note:** `AMSMaterialsSetting` now uses Orca's custom `ComboBox` on macOS as well, because the favorite-star UI depends on the custom `DropDown` item renderer. I was able to test this on Windows, but macOS/Linux smoke testing is still needed and would be appreciated.

- Opened the AMS Materials Setting dialog from an editable AMS slot
- Confirmed clicking a star toggles favorite state.
- Star clicks do not select the filament row.
- Dropdown remains open after toggling a favorite.
- Confirmed favorited filaments appear under `Favorite filaments`.
- All compatible filaments remain visible under `All filaments`.
- Confirmed Filament still selected as before
- Confirmed favorites persist after closing and reopening the dialog.
- Confirmed favorites persist after restarting OrcaSlicer.
- Confirmed the favorite IDs are saved in `OrcaSlicer.conf` under `ams_favorite_filament_ids`.
- Bambu/RFID/read-only filament slots continue using the existing read-only display behavior.
Not tested:
- macOS
- Linux/Wayland
These should be tested, `ComboBox` behavior not tested on macOS.

Five Plater::TakeSnapshot guards in GUI_ObjectList were unnamed temporaries, so snapshots were allowed again as soon as the snapshot was taken. Naming them keeps the suppression until the edit is done, as everywhere else.
The importer assigned pick_file.empty() and pattern_bbox_file.empty(), a bool, to the string fields, storing a one-character string instead of the path.
Every slider in the texture displacement panel now takes an exact number,
either by Ctrl+clicking the track or through a small edit icon at its right
end. Both routes end in ImGui's own temp-input mode: the icon only asks ImGui
to focus the slider, which is what turns it into an input box, so the parsing,
the clamping and the Enter/click-away behaviour stay ImGui's rather than
becoming a second implementation.
The mechanism lives in one helper, typed_row(), with a float and an int form
over it. float_row() and int_row() are thin wrappers on those, and the six
sliders that previously built their widget inline (brush size, smart fill
angle, edge fade amount, remesh sharp angle, refine resolution and the uniform
triangle budget) now go through the same path.
Each slider carries a tooltip with its description and its range. The range is
derived from the bounds and the format string the slider is already given, so
no row states them twice and the tooltip cannot drift from the track. The
tooltip allows hovering while disabled, since several rows are drawn inside
disabled_begin(), where a greyed slider is exactly when the explanation is
wanted.
The panel's "?" popup gains an entry for each of the two ways in, appended to
every tool's shortcut list and shown on their own when no painting tool is
selected, where that popup was previously empty.
