* Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill
For patterns with curved/turning anchor lines (Hilbert Curve, Octagram
Spiral), the bridge_over_infill algorithm produced incorrect results:
1. determine_bridging_angle: sampling curved anchor orientations
produced noise across all turning directions (0/90/180/270°)
instead of a single dominant one, yielding unstable bridge angles
with 180° spread. Fix: use the configured infill_direction + 90°
directly, bypassing the noisy sampling. The old blind +0.25*PI
(Hilbert) and +1/16*PI (Octagram) offsets are removed.
2. construct_anchored_polygon: curved Hilbert/Octagram anchors
intersected each vertical scan line many times at wildly different
Y positions, producing chaotic polygon sections — holes in random
places, bridges over air, rotated bridges. Fix: replace the curved
infill polylines with synthetic straight lines parallel to
infill_direction, spaced at the real infill line spacing
(flow_spacing / density). Lines are centered on the limiting_area
bbox center so that after rotation they span the full bridged_area.
Anchors are left at full bbox length (not clipped) to guarantee
every scan line finds an anchor.
Rectilinear and other straight-line patterns are unaffected.
Known limitation: some bridge edges may still terminate over air in
edge cases where the nearest synthetic anchor line is more than one
infill spacing away from the bridge boundary. This will be addressed
in a follow-up.
* fix: anchor internal bridges to actual sparse infill
Preserve real anchors across regions and align plane-path anchor origins with printed infill. Respect lower-layer rotation templates and model alignment, and sample curved bridge boundaries more finely.
Add regression coverage for anchor alignment, bridge angles and region isolation, with Orca comments explaining the geometry constraints. Verified 175 FFF tests before the comment-only follow-up; preserve CRLF in modified files.
* Fix internal bridge support contacts and separated infill origins
Restore anchor contact after bridge smoothing and share per-body pattern origins between anchors and printed infill. Recompute origins when preparation settings change.
Cover multiline counts 1, 2 and 3 and add regressions for printed bridge support, separated infill alignment and reslicing.
* Add explicit standard headers to PrintObject tests
* test: cover surface centering when infill settings change
Verify top and bottom Archimedean Chords and Octagram Spiral paths after switching centering modes or toggling separated infills. Compare reslicing against fresh slicing and document dependent infill invalidation.
* test: preserve directional surface infill when settings change
* perf: index layer islands for connected-body detection
* test: use public print pipeline for body centering checks
* build: clear 2 warnings - cast the NSTextField the class check already proved
mainframe_text_field is NSTextField* and was assigned a bare NSView*, which
Clang reports as -Wincompatible-pointer-types. Both assignments sit inside
if ([viewObject class] == [NSTextField self]), so the runtime type is already
guaranteed, and the line above the second one casts the same variable the same
way to call setTextColor. macOS only, since nothing else compiles this file.
* build: clear 6 warning categories from the clang-cl inventory
-Wmissing-braces (9). Aggregates whose first member is itself an aggregate.
GUID's fourth member is BYTE[8], so the trailing eight bytes take their own
braces. The others were reaching for zero-initialization with {0} and say {}
now. bbs_3mf's backup Task ends in an anonymous union, which needs braces of
its own; those braces initialize the union's first member rather than the one
named at the call site, so the RemoveBackup site says so in a comment.
-Wmacro-redefined (11). SendMultiMachinePage.hpp defines five names that
Preferences.hpp, PresetBundleDialog.hpp, ExportPresetBundleDialog.hpp and
TroubleshootDialog.hpp also define with different values, so the value in
force depended on include order. All nine of this file's DESIGN_ macros take
the SEND_ prefix it already uses for its own macros, values unchanged, so a
DESIGN_ name added elsewhere later cannot collide with it again. They read as
one page-local palette, a 900 to 400 gray ramp plus sizes, so the four with
no current readers stay: dropping them would leave gaps in a named scale. test_marchingsquares.cpp defines NOMINMAX,
which libslic3r already passes as a PUBLIC compile definition, so it takes
the #ifndef guard the other suites use.
-Wbraced-scalar-init (3). Two PushStyleVar calls resolve to the float
overload, so the braces were initializing a scalar. ConfigOptionFloatsNullable
already takes an initializer_list, so the inner braces did the same thing.
-Wmicrosoft-goto (2). Both gotos in copy_file_gui jump forward over the
initialization of size, dwRead and dwWrite, which only MSVC accepts. Those
declarations move up to join the others at the top of the function.
-Wunused-private-field (3). Every use of ColourPicker's m_clrData and
m_picker_widget is behind !defined(__linux__), so on Linux they are written
and never read; the members now carry the same guard. ParamsPanel's
m_size_move is read nowhere. Tab has its own, which is the one Tab.cpp uses.
-Wnonportable-include-path (2). BaseException.h asked for "stackwalker.h"
and the file on disk is StackWalker.h.

# Description
This PR introduces a publish workflow for sharing selected slicer
settings in .3mf projects without exposing or overriding the recipient's
complete printer, filament, or process profiles. A published file
specifies "requirements" for a model — printer, process, and per-slot
filament requirements — while importing it preserves the rest of the
recipient's workflow.
Publish dialog (File → Publish, Ctrl+Shift+E)
- Tabbed dialog (Printer / Filament / Process) with search, Select All /
Select Visible, and DPI rescaling.
- Per-material pages expose three kinds of content: individually
selected filament keys, a Full Publish toggle that embeds the slot's
entire filament preset, and required type and color rows for the slot.
- Publishing is allowed with no settings selected (the file then carries
only identity/requirement data).
- Reuses configuration value formatting extracted into a shared
ConfigValueFormatter.
Export
- Published 3MFs carry published, published_keys, and
published_material_keys metadata.
- A minimal export mode serializes only the selected values, material
identity, and plate geometry, omits embedded preset files, and masks
full-publish vector options to the author's slot so unrelated slot data
never leaks into the file.
Loading
- Only author-selected settings are applied; the recipient's presets are
otherwise preserved and structural/non-publishable keys are protected
(skipped keys are reported).
- Material settings match by filament ID, type, vendor, and slot.
Per-slot type requirements keep a matching receiver material, replace a
mismatched slot with the first same-type library filament (with a
notification), and fall back to a temporary embedded preset or skipped
keys when no match exists. Required colors are applied regardless of the
type match.
- A published 3MF loads as a new project: its path is not adopted as the
project filename (Save prompts instead of overwriting the shared file),
the title reverts to "Untitled", and the published metadata is stripped
so a later save produces a normal 3MF.
- Customized-preset and modified-G-code warnings are suppressed, since
the author's presets and G-code are not applied.
- Previously published 3MF files continue to load through the existing
matching path.

## Tests
Added tests covering:
- Coverage for export slot masking, metadata round-trip,
type-match/replace/fallback semantics, slot growth, and skipped-key
reporting.
build: clear eleven single-site clang-cl warning categories
Each of these is the last site left in its category, and every one is the
compiler saying it cannot tell what the code meant. Nothing here changes
defined behavior.
- OrcaSlicer_app_msvc.cpp printed a DWORD with %d
- StackWalker.cpp ran delete[] through an LPVOID
- ToolOrdering.cpp used a bare ; as a deliberate skip loop's body
- WipeTower.cpp had finish_block_tcr = finish_block_tcr, so the branch that
reached it did nothing. Folding the condition into the enclosing if leaves
the other branch untouched
- GCodeProcessor.cpp had an else binding to the inner if while the outer if
carried no braces
- AmsMappingPopupUpdate.cpp wrote >= 1 || <= 3 where its own comment says &&
- CalibrationWizardPresetPage.cpp left max_decimal_length unset through a
pair of conditions that cover every value but not visibly so
- DevManager.cpp bound map elements to pair<K, V> rather than
pair<const K, V>, copying every one
- SyncAmsInfoDialog.cpp had extraneous parentheses around a comparison
- Http.cpp had if (speed > 0.01) speed = speed;. speed now starts at 0 as
well, because curl_easy_getinfo leaves the target untouched when it fails
and the value reaches Progress either way
- SnapmakerPrinterAgent.cpp truncated npos into an unsigned int, so the
!= npos guard was always true. A colour with no # still yields 0, because
the wrap produced 0 as well
Nine categories go to zero. -Wtautological-overlap-compare and
-Wsometimes-uninitialized reach zero when #15583 merges their second site.
config_substitution_rule is a const enum with a constant initializer, so a
lambda can read it without capturing it. Capturing it explicitly is what
-Wunused-lambda-capture reports.
The category was taken to zero by #15417 and merged on 2026-09-02. These
three sites arrived on 2026-09-08 in bcb4f17d9a, "fix(cli): resolve inherited
presets through vendor manifests" (#15438). All three lambdas still read the
value, which needs no capture and is unchanged.
fix: report the real error when a Windows G-code export fails
copy_file built its failure message as "Error: " + errCode. Adding a DWORD
to a string literal is pointer arithmetic, not concatenation, so the pointer
lands errCode bytes into an 8-byte literal and runs past its end for any code
above 7. std::string then calls strlen on it and throws length_error, and the
catch(...) in BackgroundSlicingProcess::finalize_gcode replaces the diagnosis
with "Unknown error occurred during exporting G-code."
Every code a user is likely to hit is past the end: write-protected media is
19, no media 21, a full disk 112, and a destination held open by another
program 32. Codes 1 to 7 stay inside the literal and produce a truncated
message instead. So the "Maybe the SD card is write locked?" text has not
been reachable on Windows since this path was added in #2923.
Now that it is reachable, that guess only fits removable media, so it is
conditional on m_export_path_on_removable_media. The existing string is
untouched and keeps its 23 translations; the fixed-drive case adds one string.
* build: clear 2 warnings - a precedence bug and an arm64-only pragma
Both were found by promoting every warning to an error across the CI matrix.
Neither is reported by clang-cl on Windows x64, which is the configuration the
#15374 inventory measures.
LineSplit.hpp reserved with path.size() + closed ? 1 : 0. Addition binds
tighter than ?:, so that parses as (path.size() + closed) ? 1 : 0, and the
function returns early when path is empty, so the condition is always true and
the reserve is always 1. The vector then grows by reallocation instead of
reserving once. Output is unaffected, since reserve only sets capacity.
Reported by Clang on Linux, macOS and Flatpak; GCC does not diagnose it.
Int128.hpp declared #pragma intrinsic(_mul128) under _WIN64, which is defined
on Windows arm64 as well, where that x64 intrinsic does not exist. The call
site at line 190 is already guarded on _M_X64 and carries a comment saying
ARM64 has no _mul128, so the pragma now uses the same guard. x64 is unchanged
because _M_X64 is defined there.
* build: clear 1 warning - CLI error label prints 1 instead of a name
construct_assemble_list is a function, so streaming it converts the function
pointer to bool. When that catch block fires the CLI prints "1: <message>".
This line was already fixed in #5963 and came back in the wholesale revert of
that PR two weeks later, which was reverting an auto-orientation regression
somewhere in its 184 files. The string is restored exactly as it was merged
then.
Both are in our own code and neither shows up in a clang-cl or clang census,
so the Windows and CI matrices have never reported them.
FillRectilinear.cpp draws two trapezoid diagrams whose lines end in a
backslash, which continues a // comment onto the next line. GCC calls that a
multi-line comment. The diagrams are now block comments, where the rule does
not apply, and the drawings are unchanged.
CutObjectBase has a user-provided operator= and a virtual destructor, either
of which deprecates its implicitly generated copy constructor. bbs_3mf.cpp
copies the type through CutObjectInfo. The copy constructor is now declared
and defaulted, leaving the class with no implicit copy member. Move
operations were already suppressed by the user-provided operator=, so nothing
changes there.
Every edit makes the precedence the compiler already applies explicit. None
of them regroups an expression, so behavior is unchanged at all eight sites.
Strip parentheses and whitespace from the diff and the token stream matches.
GCodeProcessor.cpp:1472 tests == where the symmetric clause below tests !=,
which reads like a typo and is not one. A comment now explains why.
OrcaSlicer.cpp:4760 was the only judgment call. Its leading !is_seq_print is
bare while both operands are parenthesized, so the written form matches what
the compiler does. Kept rather than guessed at.
ImGui::Text and ImGui::TextColored take a printf format, so these six sites
passed data where a literal belonged. A % in that data reads a vararg that
was never supplied.
Three sites in GLCanvas3D's paint toolbar passed filament text, which comes
from the filament preset config and is user-editable. Two more passed
translated strings, where a % in any of the 23 catalogs does the same.
GLGizmoSimplify passed its progress label.
That label had been built with an escaped %% because it was being used as a
format string. Passing it as an argument instead needs a single %, so it
still renders as "42%".
ToUTF8() returns a buffer class, which converts to const char* for a named
parameter but not through varargs, so those two sites need .data().
GLGizmoSimplify.cpp:335 is unchanged, because _u8L("%d triangles") is passed
with a real argument and has to stay a format string.
Fix two stack buffer overflows in ADMesh stl_read (solid name + MW parse)
Bound the ASCII-STL solid-name fscanf scanset to the buffer size, and bound
the OrcaSlicer-specific "MW" metadata sscanf %s conversions to their buffers:
- fscanf(fp, " solid %[^\n]", solid_name) -> %255[^\n] (solid_name[256])
- sscanf(mw_position+3, "%s %s %s", ...) -> %15s %127s %15s
(version_str[16], model_id_str[128], country_code_str[16])
Both are reachable by opening a crafted .stl and overwrite saved stack state
(instruction-pointer control on the no-PAC arm64 macOS build). The solid-name
defect is inherited from the shared ADMesh loader (bambulab/BambuStudio#12153);
the MW parse is OrcaSlicer-specific.

# Description
The pre-slice wipe tower size estimate existed twice:
`Print::wipe_tower_data()` (validation) and
`PartPlate::estimate_wipe_tower_size()` (GUI placement clamp, default
placement, preview, arrange, CLI placement) — with a third partial copy
in the CLI, which resolved the brim itself around the second. They were
hand-written twins reading their inputs from different places, so
validation could measure a tower with one number after the clamp had
placed it with another.
This PR extracts the estimate into one function,
`estimate_wipe_tower_footprint()` in
`src/libslic3r/GCode/WipeTowerEstimate.{hpp,cpp}`. It takes a
`ConfigBase&` (static `PrintConfig` and GUI/CLI `DynamicPrintConfig`
both work), the filament count, layer height and tallest object height,
and returns width, depth, height and the resolved brim width.
`Print::wipe_tower_data()` and a new
`PartPlate::estimate_wipe_tower_footprint()` become thin adapters around
it; `PartPlate::estimate_wipe_tower_size()` had no callers left and is
deleted.
**Inputs made to agree** — sharing the arithmetic is not enough when
each caller derives the inputs from its own view of the model:
* **Layer height** — thinnest layer among the objects on the plate,
resolved per object (Print used the first object's, PartPlate the
preset's).
* **Objects setting the height** — `PartPlate::get_extruders` counts an
object if *any* instance is on the plate, matching `PrintApply` (it only
looked at instance 0).
* **Height per object** — per on-plate instance, from the cached convex
hull (same z extent as the mesh). `PrintObject::size()` still measures
the model's first instance, so objects whose instances differ in scale
or x/y tilt can still disagree; that is inherent to the two data
sources.
* **Wipe tower filament** — counted for every caller, since
`Print::extruders()` adds it to the tool ordering even when unused.
* **Rib width cap** — kept for both (Print lacked it).
* **Config source** — everything read from the config passed in
(PartPlate read `m_print->config()`, stale on fresh plates and in the
CLI).
* **Dual-nozzle test** — `nozzle_diameter.size()` from the config for
both.
**One decision about whether a tower exists.** The rectangle branch
sized a tower the generator never builds while the rib branch reported
none for one it does; with rib as the shipped default, a single-filament
plate that still prints a tower (custom G-code tool changes) validated
against depth 0, collapsing the collision/exclusion hull to a point. The
purge volume is computed first, and an empty footprint is returned only
when nothing is purged, there is no tool change, and nothing else puts a
tower on the plate. The reason a single config cannot see arrives as a
resolved input: validation counts `Print::extruders(true)`.
A raft is deliberately **not** one of those reasons.
`DynamicPrintConfig::normalize_fdm_2` clears `enable_prime_tower` for a
plate that purges one filament unless smooth timelapse or wrapping
detection is on, and `Print::apply()` runs it, so a raft alone leaves no
tower to reserve for. (It also keeps the tower for a single *mixed*
filament, which this does not model — `Print::extruders(true)` does not
expand mixed filaments.)
**Two implementation notes:**
* Enums are read **by value**: a preset-built `DynamicPrintConfig` holds
`ConfigOptionEnumGeneric`, so a `dynamic_cast` to `ConfigOptionEnum<T>`
is null for exactly the config the GUI and CLI pass. The tests build
their configs the way `PresetBundle::full_config()` does, so that
storage is what gets tested.
* `PartPlate::estimate_wipe_tower_footprint()` is CLI-reachable, so
`get_extruders(bool)` gained a config-taking core with the identical
body; the GUI wrapper passes the app's presets, the adapter passes the
config it is given. `get_extruders_under_cli()` was not substituted: it
filters the plate's instances differently (skips unprintable ones, keeps
ones the plate flags as outside), so the GUI's filament set would have
changed in edge cases.
**Also fixed here:** `WipeTowerData` carries the effective width — set
by the estimate, and then by both planners at generation, so it never
disagrees with its neighbour `depth`; the preview and the containment
check take *whether there is a tower at all* from the footprint instead
of each re-deriving it; the config-taking `get_extruders` answers for an
object-less (`.gcode.3mf`) plate the way the wx overload does; the
preview takes body *and* brim from the plate's own footprint (an auto
brim drew every plate with the selected plate's brim);
`estimate_wipe_tower_polygon` builds its margin from the resolved brim
("Auto" gave a margin of 0) and no longer calls `std::clamp` with `hi <
lo`; the estimate falls back to declared defaults instead of hand-copied
constants. `estimate_wipe_tower_size()` /
`estimate_wipe_tower_polygon()` lose four parameters every caller took
from the same config.
## Behaviour changes reviewers should know about
G-code is never affected; no 3MF, profile or string changes. But this is
**not** a pure refactor:
1. **Validation now reserves what the placement clamp reserves**, which
is in places larger than before. A saved 3MF with a tower close to an
exclusion area or the rear edge can be rejected where it previously
sliced; dragging resolves it since the clamp agrees. Nothing re-clamps a
stored position on load (out of scope; the CLI side lands with #15518).
2. **`PartPlate::get_extruders` counts any-instance-on-plate**, which
reaches every caller of it, not only the estimate. It is `PrintApply`'s
rule and closes a GUI/CLI divergence.
3. **`estimate_wipe_tower_polygon`'s rear/right bound is looser by one
brim width** (it subtracted the brim twice).
4. **A single-filament plate with a rib wall no longer reserves a
phantom tower.**
5. **A single-filament plate whose tower comes from wrapping detection
is now validated against the bed.** Neither the old estimate (which read
only the wall type and smooth timelapse) nor the old containment gate
(the filament count or smooth timelapse) knew about that tower, so
between them it was never checked. It is printed, so it can be rejected
now.
Not addressed: the estimate still does not read `wipe_tower_type` or
per-filament `filament_prime_volume`, inherited unchanged from both
copies (the generated Type 1 tower is ~10 mm larger than the estimate on
Bambu profiles). #15516 mirrors the planners and folds into this
function on rebase.
## Verification
Before/after on the same fixtures with a main build and this branch, all
numbers read from the CLI (details, method and the real-tower and
arrange-clamp tables in the first comment):
| Fixture (divergence) | Side | Before (w × d, mm) | After (w × d, mm) |
|---|---|---|---|
| control | GUI/CLI · validation | 23.585 × 23.585 · 23.585 × 23.585 |
same |
| per-object layer 0.1 | GUI/CLI · validation | **23.585** · 31.637 |
**31.638** · 31.637 |
| unused `wipe_tower_filament` | GUI/CLI · validation depth | **39.332**
· 44.542 | **44.541** · 44.542 |
| tall object, instance 0 on another plate | GUI/CLI · validation |
**23.585** · 29.391 | **29.390** · 29.391 |
| rib cap binds | GUI/CLI · validation | 11.170 · **13.910** | 11.170 ·
**11.170** |
Before, the two estimates disagree on every divergence fixture; after,
they agree to the 0.001 mm bisection resolution, the control is
unchanged, and G-code is byte-identical. GUI screenshots of the preview
on both binaries are in the same comment.
The table was measured on the first commit; none of its fixtures uses a
raft or a zero purge volume, so the second commit does not move them.
G-code equivalence was re-checked on the final tip: `Cube.3mf` sliced by
a `main` build and by this branch is byte-identical.

/>
**Per-object layer height reaching the preview.** One object with a 0.1
mm override against a 0.2 mm preset. `main` sizes the previewed tower
from the preset, so it is smaller than the one validation reserves and
the one that prints; this PR sizes it from the object. Captured
headlessly on both builds from the same project, top view:
<img width="1408" height="596" alt="D_per_object_layer_height"
src="https://github.com/user-attachments/assets/989920fc-9f14-4658-8a3d-681c92a7f754"
/>
Measured over the four evidence fixtures on both builds, this is the
only one of the corrected inputs that changes what is drawn: the others
(an object contributing through a non-zero instance, an unused
`wipe_tower_filament`) change the estimate by amounts confirmed through
the CLI bisection above, but leave the rendered tower pixel-identical.
Arrange is unaffected either way — the tower enters the arranger as a
fixed obstacle (`m_unselected`), so it never moves.
## Tests
* `tests/libslic3r/test_wipe_tower_estimate.cpp` (10 cases / 104
assertions): rectangle and rib sizing, stability floor and auto brim,
single-filament cases (timelapse, wrapping, and a raft *not* reserving
one), a tool change reserving the floor when the purge volumes resolve
to zero, both wall types agreeing on tower existence, dual-nozzle
volume, the shipped flush-matrix path, default fallback for a missing
key, and a {rectangle, cone, rib} × {type1, type2} matrix asserting a
preset-shaped `DynamicPrintConfig` and a static `FullPrintConfig` give
the same footprint.
* `tests/fff_print/test_wipe_tower.cpp`: what `Print` feeds the
estimator — thinnest object layer height, effective width reaching
validation, the width staying current through generation, a
single-filament plate reserving a tower only when one is really printed
(raft no, smooth timelapse yes), and a wrapping-detection tower being
bed-validated. The last two fail on `main` and on the first commit of
this PR.
* Full suites green on this branch: `libslic3r_tests` 342 cases / 58325
assertions, `fff_print_tests` 174 cases / 3152 assertions. `--target
all` builds clean (including `OrcaSlicer_profile_validator`, which needs
`-DORCA_TOOLS=ON`). No new warnings.
* CLI evidence run above; its unused-`wipe_tower_filament` fixture is
also the regression check for the adapter under the CLI, which no unit
test can reach (`PartPlate` needs a GL context).

Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
A plain CLI slice ran none of the placement sites, so a stored or
default tower position that no longer fits the tower the plate needs
went straight to the generation-time error. The slice loop now applies
the same clamp the GUI applies on reload to every plate it is about to
slice, skipping only plates that print no tower: by-object plates with
more than one instance, and plates whose footprint estimate is empty
(which covers single-filament plates without smooth timelapse, wrapping
detection or a raft). The plate's filaments come from the same
config-driven derivation the estimate uses everywhere else.
The two arrange sites read the brim width from the right option when
padding the default position; an auto brim uses its 8 mm cap there,
since the object heights are unknown before the estimate runs.
The preview brim, the placement margin and the pre-generation validation
warning each decided on their own whether the tower has a Type2 cone
base, reading the wall type and cone angle three different ways. The
preview's read cast the preset's enum to ConfigOptionEnum<T>, which a
preset-shaped config never holds, so the cone base was never previewed.
estimate_wipe_tower_first_layer_outline now answers that question once,
beside the footprint estimate, from the config and the resolved planner;
all three sites take the outline from it. The libslic3r case reads the
outline off a preset-shaped config, where the old cast came back empty.
The validator forces a two-filament print with the prime tower on and
slices it at the config default position (x 15, y 220), which lies off
any bed shallower than the tower. It calls validate() but slices
regardless, so the off-plate tower was exported silently; with the
generation-time footprint check it is rejected instead, and 522 of the
1013 printer presets failed the slice check.
The validator now positions the tower the way the GUI and CLI do before
slicing: beside the centred cube, clear of the edge exclusion strips some
beds carry, then pulled inside the printable outline by the tower's own
estimated footprint.
The clamps and validation work from estimates. Once the tower is
generated, _make_wipe_tower re-tests the exact first-layer footprint,
brim and cone base included, against the printable area and the
exclusion zone, so an off-plate tower fails with a clear error instead
of exporting unprintable G-code. The rectangle-wall mesh footprint
learns the Type2 cone base so that check and the post-generation
validation see the real outline.
Pre-generation, validation hard-checks the body plus an explicit brim
and warns on the estimated auto brim and cone base with the existing
"may collide" strings, so the user hears about a marginal position on
the first slice rather than only at generation time.
Two fff_print fixtures that print a tower at the default position move
it onto the 200 mm test bed, as the multifilament fixtures already do:
the shipped default y of 220 is off that bed, and the backstop now says
so instead of exporting the tower.
Smooth timelapse no longer charges a prime volume it does not purge. A
tower printed with no tool change is exactly the idle depth: the
stability minimum for Type2, the wrapping detection depth for Type1.
Charging a full prime_volume on top made the previewed and arranged
tower deeper than the one that is printed.
The Type2 half of "a tool change reserves a tower whatever the purge
volumes resolve to" arrives with the base commit; here it only has to
survive the planner split, since Type1 already reserves per filament.
The wipe tower filament only joins the tool ordering when there is a
tower to join, which is the has_wipe_tower() half of the guard
Print::extruders applies.
The shared estimate reserved every tower with one volume-per-purge rule
and the stability floor. Both planners do more: WipeTower (Type1) wipes
each filament's own prime volume in whole lines, one block per
adhesiveness category sized by its worst layer, rams the leaving
filament at every nozzle change, and squares a rib tower from the
planned depth; WipeTower2 (Type2) spaces its lines by
wipe_tower_extra_spacing, not the Type1-only infill gap, and its extra
flow cancels out of the depth. Both extend the ribs rather than the body
below the stability minimum, size every layer including a thinner first
one, and lay the brim in whole loops, WipeTower reporting half a spacing
of line width on top.
All of that now lives in estimate_wipe_tower_footprint, fed the planner
(resolve_wipe_tower_type mirrors Print::wipe_tower_type and the CLI's
Bambu Lab detection) and the filament ids rather than a count. Print
passes its own tool set; the PartPlate adapter derives the plate's ids
from the passed config and treats an explicit count as a floor, so the
CLI's count-only callers size per filament too. The placement clamp also
reserves a Type2 cone's base bulge, which the body box does not cover.
The planner-mirroring helpers sit beside the planners in WipeTower and
WipeTower2 so the two stay in sync; the libslic3r cases pin them to
footprints measured from generated G-code.
Validation grows the estimated body by the brim before the tower is
generated, so a tower whose brim leaves the bed is rejected up front
instead of at export. The scene reload re-clamps the stored position,
since set_default_wipe_tower_pos_for_plate does not rerun when painting
changes the filament count. The rectangle-wall footprint polygon gets its
two missing brim corners (it was a skewed quad), so the post-generation
check covers the whole brim.
A raft is not a reason to reserve a tower. Print::apply runs
normalize_fdm_2, which clears enable_prime_tower for a plate that purges
one filament unless smooth timelapse or wrapping detection is on, so a
single-filament plate with a raft prints no tower at all and the estimate
was reserving bed area for one. Drop the input; need_wipe_tower is now
exactly the two exceptions normalize_fdm_2 honours, named there so the
next reason added has to be checked against it.
The GUI preview and the validation containment check each re-derived
"is a tower printed here" from the filament count instead of reading the
estimate, so both missed the towers printed with no tool change to purge
for. They now take the answer from the footprint, which is the drift this
shared estimate exists to remove. A tower that is not printed estimates to
zero, so its hull is degenerate and every check on it passes trivially -
the containment check needs no gate of its own.
WipeTowerData::width was written only by the pre-generation estimate and
left at zero for the whole post-generation life of the Print, while its
neighbour depth held the real value. Set it from the generator in both
branches.
The plate's height scan transformed every model part's full mesh per
instance on each scene reload, discarding all but the z extent. The
cached convex hull has the same z extent.
A plate loaded from a sliced .gcode.3mf holds no objects and its filaments
live in slice_filaments_info; the config-taking get_extruders overload
returned an empty list for it, which sized the tower for a placeholder two
filaments. It now answers the way the wx overload does, without reaching
the plater.
Also drop estimate_wipe_tower_size, which has no callers.
import_presets reduced each zip entry to a basename by stripping only
'/', so on Windows an entry named with '\' separators kept its
directory components and was extracted wherever they pointed. Strip
both separators, and reject any entry whose name still escapes the
extraction folder.
The preset name from the JSON and the bundle id from
bundle_structure.json were joined onto the preset directory unchecked
as well, which let either of them write outside it on every platform.
Both are now validated before anything is written.
The check is the is_path_within_root helper the 3MF importer already
had, moved to Utils so both importers share it. It treats '/' and '\'
as separators on every platform, so a bundle that would escape on one
OS is rejected on all of them.
* Make tree support deterministic without giving up its parallelism
* Break equal-distance ties in the tree support MST by coordinates
* test: cover the determinism this PR fixes
The MST unit tests here cover the tie-break, but the drop_nodes rework
has no test.
Adds two cases to the tree support suite. The thread-scheduling one
slices five configs twice each and compares the support point sequence,
which is what the node ordering moves. The MST tie one pins the branch
diameter and line width that carry Prim's equal-distance ties into the
toolpaths.
slice_with_tree_support takes an optional config list so the second case
can add the tree parameters it needs, and the double-slice comparison is
shared rather than written twice.
Both fail on main without this PR. The first passes from 60d1ceb580, the
second from e148865dd6.

Its output is not bounded to [-1, 1], so it scales past the configured

Fix nondeterministic slicing: order per-layer intersection lines canonically
Facet processing in slice_make_lines() is parallel, so the per-layer line
order depended on thread scheduling. make_loops() consumes that order for
island order and loop start vertices, so the same model could slice to
different G-code run to run.
Sort each layer's lines by a topology-based key. edge_type and flags are
appended to the key purely to break ties: two lines can share every id and
endpoint (a Horizontal facet can emit such a pair) and std::sort is not
stable, so without them that pair's order would stay thread-dependent.
The bed was declared as 0x0, 20x0, 200x200, 0x200 - a triangle - where the
0.4 nozzle profile and the printer have the 200 x 200 square. Found by the
profile validator once it placed the prime tower beside the test cube:
no tower fits inside that outline.
# Description
This PR redesigns `filament_id` across OrcaSlicer's profile library, so
that one filament
product now carries one consistent id everywhere it ships, instead of a
hand-written value that
unrelated materials routinely shared. Minting scripts and CI checks come
with it so future
profiles comply by construction: a new filament takes its id from the
tool, and the checks
reject a hand-written, duplicated or drifted one before it can merge.
Unique, non-duplicated ids are a precondition for AMS-style spool
syncing to be dependable —
the id is what a printer matches a physical spool against, and while two
products share one, the
match is a coin toss. This PR lays that groundwork. A follow-up PR will
publish an OrcaSlicer
materials reference on the wiki, giving every system profile one place
to point at.
`filament_id` names one filament product, and it is what a device
matches a physical spool
against: Bambu AMS, Creality CFS, the Qidi box, Klipper and Snapmaker
all resolve a tray to a
preset by id alone, first hit wins. Those ids were written by hand, and
on `main` 99 of them
stand for 674 different products — `GFL99` alone covers 132, from
Anycubic PLA to Bambu PLA
Matte. Every consequence is silent: a spool resolves to whichever preset
happens to load first,
tray names and support-material flags are read off the wrong material,
and the second preset
holding a duplicated id disappears from the tray-edit dialog entirely.
The id is now a hash of `(filament_vendor, filament_type, filament
name)`, so one spool product
carries one id in every bundle that ships it, two vendors shipping the
same product converge on it
without coordinating, and a collision cannot be authored by hand. Every
ambiguity across 48
vendors is fixed rather than excused — no grandfather list and no
per-vendor carve-out, Bambu's
bundle included — and the resulting landscape is frozen in
`scripts/filament_id_snapshot.json`,
so a change to any filament's identity lands as a reviewable diff to one
file. CI now runs the
duplicate-subtype validation tree-wide instead of over Bambu only.
Letting the id follow the product meant correcting the identities
themselves. Generics that
shipped under a vendor prefix now have one name and one id everywhere
(`Blocks Generic PETG` is
`Generic PETG @Blocks`), presets whose `filament_vendor` or
`filament_type` contradicted the
spool are fixed, and duplicate pairs are collapsed onto the
better-configured survivor. Renames
carry `renamed_from`, so existing projects and user presets keep
resolving.
Bambu's printers, its AMS and its cloud know only Bambu's own catalog
ids, so those ids leave
the profiles entirely. The Bambu bundle mints like every other vendor,
and the printer agent
swaps in the catalog value only where an id crosses to or from a Bambu
printer — outbound MQTT
and FTP, the AMS mapping sent with a job, the ids written into a 3mf the
printer will read —
mapping back on the way in, so status messages, SD-card prints and
projects saved by an older
Orca or by BambuStudio all still resolve. The correspondence is
generated from BambuStudio's
own shipped bundle by `scripts/update_bambu_filament_ids.py`; an id with
no row is forwarded
untouched, a missing or malformed map degrades to no translation rather
than taking the app
down, and an agent whose printers already speak Orca's ids translates
nothing.
Two device-side bugs this work surfaced are fixed here as well. The Orca
Filament Library was
missing from the AMS material and calibration dialogs, which treated a
filament with no
`compatible_printers` as compatible with nothing while the rest of the
app treats it as
compatible with everything; and Creality CFS sync on a K2-family stock
0.4 nozzle picked the
wrong preset, an imprecise matcher that duplicate ids had been masking.
`docs/HLSD/filament_id.md` is the authoring rule for all of this.
`scripts/orca_id_tool.py`
mints both `filament_id` and `setting_id`, replacing
`assign_vendor_setting_ids.py`, and the
local `check_profile` scripts gained per-vendor scoping so one vendor
can be checked without a
tree-wide run. `scripts/tests/` covers the tooling; `tests/slic3rutils/`
covers the boundary
translation and the CFS matcher.
Ids change for most products and nothing forwards the old value, so a
tray or a calibration
record still holding one falls back to matching by filament type until
the filament is selected
once. Beyond the profile fixes above no print settings change, except
that a few presets stop
claiming printers a dedicated variant already covers.

`scripts/check_profile.sh`, the local twin of the "Check profiles" CI
job, with
`scripts/check_profile.bat` as its Windows entry point, passes on this
branch: the extra JSON
check reports no errors and no warnings, system validation and the now
tree-wide
filament-subtype check load all 66 vendors cleanly, all 1013 printer
presets slice, and
custom-preset validation passes against every fixture archive from
v1.9.0 to v2.4.2.
The id tooling has 176 unit tests (`python -m unittest discover -s
scripts/tests`). The C++
suites pass too — 332 in `tests/libslic3r` and 126 in
`tests/slic3rutils`, the latter including
the boundary-translation and Creality CFS matching cases added here.

filament_id is the plain mint of the product triple (filament_vendor,
filament_type, filament name), and nothing else feeds it. The tooling used to
accept any salt iteration of a preset's own triple, and its minting policy
stepped past ids that other products held in the tree or in the snapshot, so
which id a product got could depend on history. Every "salt split" in the tree
masked a redundant preset rather than a real need, and no shipped id is
salted, so salting goes entirely: no salt parameter, no id policy object, and
--generate no longer reads the snapshot.
--check now holds every declared and every inherited id to that one value and
lists each preset that misses it, variants under a wrong root included, instead
of folding them into the root's error. Two products whose triples mint one id
is reported as a collision naming both, and --generate refuses to write it;
the remedy is a rename so the triples differ. The Bambu catalog map generator
keys its rows by the same mint rather than by what the tree already ships.
No id changes: all 913 ids in the tree are already the mint of their triple,
so --generate is a no-op and the snapshot is untouched.
