The Emboss text-cut workflow can crash with SIGBUS at a stack-guard page
on macOS (and equivalent on Linux) when CGAL's
Polygon_mesh_processing::corefine falls back from filtered interval
arithmetic (Epick) to exact rational arithmetic (Epeck / mpq_class).
On near-degenerate inputs -- coplanar triangles in the projection
footprint, very thin font stems, sharp edges or seams under the text --
CGAL's Filtered_predicate_with_state cascade ends up inside
Triangulation_2<Projection_traits_3<Epeck>>::march_locate_2D, whose
recursive walk plus mpq_class arithmetic frames overflows the worker's
4MB default stack. The fault address sits exactly inside the next
thread's guard page, which is the textbook macOS signature.
Crash trace (BambuStudio v02.07.00.55, macOS 26.4.1 arm64, embossing
text into a model):
__gmpn_mul_1
__gmpz_mul / __gmpq_mul
CGAL::determinant<mpq_class>

Slic3r::cut_surface
Emboss::cut_surface_to_its
Emboss::GenerateTextJob::get_text_mesh
PlaterWorker::PlaterJob::process
The thread's stack region in the report was exactly 4128K -- the
default 4MB plus a small TLS overhead -- and the faulting address hit
the adjacent guard page. We have one observed reproducer; the 16 MB
value is chosen as 4x defensive headroom over that, not as a measured
upper bound. Future heavier emboss inputs may need more.
Cumulative cost on a 64-bit target. Slic3r::create_thread has 22
callsites across the codebase. Realistic peak concurrent live count is
on the order of 10-15 workers (Plater UI worker, slicing process, FDM-
support gizmo, STEP loader, network sync helpers, per-task sender
threads in TaskManager up to MaxSendingAtSameTime, per-machine info
threads in device-list dialogs, long-lived sync helpers in GUI_App).
At 16 MB reserve x ~15 = ~240 MB of address-space commitment in the
worst case, which is bounded on any 64-bit target.
Resident memory remains proportional to actual stack depth on all three
platforms: macOS / Linux mmap the thread stack and defer-commit pages on
touch, and Boost.Thread on Win32 passes STACK_SIZE_PARAM_IS_A_RESERVATION
to _beginthreadex (verified at libs/thread/src/win32/thread.cpp), so on
Windows the bumped value is the reserve, not the initial commit.
The 32-bit branch of the previous (sizeof(void*) == 4) ternary is
removed: BambuStudio doesn't ship a 32-bit build today, and the literal
makes the value easier to read at the callsite.

* feat(viewer): Display travel distance and move count in G-code summary
This commit introduces a new feature that enhances the G-code viewer by displaying the total travel distance and the total number of travel moves in the 'Line Type' summary.
This provides users with more detailed statistics about their prints, helping them to better understand the printer's behavior and identify opportunities to optimize travel moves for faster print times.
This commit also fixes a critical bug in the G-code processor where the travel distance was being calculated incorrectly. The distance variable was not being updated for non-extruding travel moves, leading to inaccurate statistics. The calculation has been corrected to ensure it is performed for all relevant move types, resulting in accurate travel distance reporting.
* Subfix segments
kilo mega giga tera peta exa
* Add missing values
* Grams to Kilos and tons
* add distance
* Fix tool view
* Record and display seam distances
Track seam-related distances in print statistics and show them in the GCode viewer. Added total_seam_gap_distance and total_seam_scarf_distance to PrintEstimatedStatistics (with initialization). In GCode::extrude_loop the code now computes seam gap and scarf distances and accumulates them for external perimeters. GCodeViewer uses the summed seam distance when the Seams option is selected in the legend.
* Fix travel / wipe distances
* Update GCode.cpp
* Filament changes estimated time

Handle user_ticket_login
Legacy Bambu network plugins completed embedded login with
user_login, which the WebView dialog already handled.
Newer Bambu login flows can complete with user_ticket_login and
return only a short-lived ticket. The external browser path already
worked because the local HTTP callback server exchanges that ticket
for tokens, fetches the user profile, and passes the resulting session
payload to change_user.
Mirror that ticket exchange path for embedded WebView login so the
dialog can handle user_ticket_login instead of silently ignoring it
after verification-code submission.

fix: OK/Cancel buttons clipped in Flushing Volume dialog (#13511)
The WipingDialog renders its UI inside a wxWebView. When the dialog
was clamped to screen size (many filaments, small displays, high DPI),
the HTML content exceeded the WebView bounds and the OK/Cancel buttons
fell below the visible area.
HTML fix:
- Convert .container to flexbox column with overflow-y: auto
- Pin .button-container with flex-shrink: 0 so it stays visible
- Allow .scroll-container to flex-grow for the table area
C++ fix:
- Replace heuristic extra_size with accurate fixed_overhead estimate
- Use correct cell height (25 DIP) matching HTML table row height
- Add screen margin for window decorations
- Enforce minimum dialog size when clamped

* Add Optimized Gyroid infill (auto-tuned wavelength + amplitude)
New infill geometry derived from FillGyroid. Two parameters are
auto-computed per-region from density, line spacing, and layer height
(no user inputs):
omega = sqrt(density_adj) / sqrt(1 + layer_height/spacing)
clamped to [0.5, 2.0]
-- Euler-Bernoulli buckling: critical load ~ 1/L^2,
so shorter wavelength under higher load (denser infill)
raises buckling resistance.
amplitude = 0.55 / omega^2, clamped to [0.20, 0.65]
-- Curved-beam bending stress: peak stress ~ A * omega^2,
so amplitude is reduced as omega rises to keep peak
fiber stress bounded while preserving stiffness.
Files:
- src/libslic3r/Fill/FillOptimizedGyroid.{hpp,cpp} (new)
- src/libslic3r/Fill/FillBase.cpp (factory case)
- src/libslic3r/Fill/Fill.cpp (switch case)
- src/libslic3r/Layer.cpp (switch case)
- src/libslic3r/PrintConfig.{hpp,cpp} (enum + label)
- src/libslic3r/CMakeLists.txt (build sources)
User-facing: appears as "Optimized Gyroid" in the Fill Pattern dropdown.
Density still chosen by user; omega/amplitude are internal.
* Fix build: layer_height is in FillParams, not Fill base
* Add ipOptimizedGyroid to multiline infill list in ConfigManipulation
* Refactor: replace ipOptimizedGyroid enum with gyroid_optimized boolean
Per @RF47's review feedback, fold the optimized wave math into FillGyroid
itself behind a per-region boolean instead of a separate infill enum.
What changes:
- New ConfigOptionBool "gyroid_optimized" on PrintRegionConfig (default
false). When unchecked, gyroid behavior is byte-identical to before.
- Optimized wave math (compute_omega_factor, compute_amplitude_factor,
f_opt, make_*_opt, make_optimized_gyroid_waves) lives inside
FillGyroid.cpp. _fill_surface_single branches on params.gyroid_optimized.
- FillParams gains a bool gyroid_optimized field, populated in Fill.cpp
from region_config alongside fill_multiline.
- UI checkbox added under Strength > Infill in Tab.cpp, label
"Optimize gyroid wave (experimental)". Toggle is hidden by
ConfigManipulation when sparse_infill_pattern != ipGyroid.
- "gyroid_optimized" added to s_Preset_print_options for preset I/O.
What goes away:
- ipOptimizedGyroid enum value, factory case, switch cases, dropdown
label, string key.
- FillOptimizedGyroid.cpp / FillOptimizedGyroid.hpp (math moved into
FillGyroid.cpp).
- Net diff drops by ~250 lines.
Existing profiles using gyroid are unaffected.
* Wire gyroid_optimized through SurfaceFillParams to FillParams
Linux build failed because line 921 in Fill.cpp populates a
SurfaceFillParams (the dedup struct), not FillParams directly.
Add the field there, in operator< / operator==, and copy it to
FillParams at both conversion sites.
* Use toggle_line for gyroid_optimized: hide row when pattern != gyroid
* Account for multiline wall thickness in omega correction (per @RF47)
When fill_multiline = N, each gyroid wall is N lines thick, so the
geometric scale fed into the buckling correction term should be
spacing * N rather than spacing. Increases omega (tighter wavelength)
when multiline is enabled, consistent with the thicker wall being
more buckling-resistant.
* Optimized gyroid via marching squares on the implicit scalar field
Per @RF47 review: replace the analytical f_opt / make_one_period_opt
wave generator (which had visible kinks at vertical-horizontal
transitions) with a marching-squares iso-extraction on the gyroid
scalar field, modeled on FillTpmsFK.cpp.
- New marchsq::GyroidField in FillGyroid.cpp evaluates
F(x,y,z) = sin(fx*x)cos(fy*y) + sin(fy*y)cos(fz*z) + sin(fz*z)cos(fx*x)
where fx = omega * baseline (anisotropic in x), fy = fz = baseline.
- get_gyroid_polylines() runs marching squares at iso=0 and converts
rings to polylines.
- _fill_surface_single() optimized branch now builds GyroidField,
runs marching squares, and skips the bb.min translate (field
output is already in absolute coords).
- Dropped: f_opt, make_one_period_opt, make_wave_opt,
make_optimized_gyroid_waves, compute_amplitude_factor. Amplitude
has no clean analog in iso-zero extraction.
- Standard (non-optimized) gyroid path unchanged.
* Mass calibration: compensate period by cbrt(omega) for x-anisotropic field
Per @RF47: optimized vs standard gyroid had different masses at the
same sparse_infill_density setting. Cause: scaling fx by omega while
leaving fy=fz at the baseline raised the surface-area-to-volume ratio
by approximately omega^(1/3) (the geometric mean of the three
frequencies).
Fix: multiply the base period by cbrt(omega) so the geometric mean of
(fx, fy, fz) returns to the standard baseline. Net effect:
fx = omega^(2/3) * baseline_orig
fy = fz = omega^(-1/3) * baseline_orig
which preserves total mass at the same density setting while
preserving the load-direction anisotropy this PR introduces.
* Switch optimized gyroid anisotropy from X to Z (per @RF47)
Z is the typical compression-load axis for FFF parts and is not at
delamination risk under compression — so the dominant failure mode
is column buckling of the vertical strands themselves. Tightening
fz directly shortens the effective vertical strand length, which
improves Z-axis buckling resistance.
Mass calibration via cbrt(omega) period compensation still applies
(scaling exactly one of three frequencies by omega; the geometric-
mean preservation argument is symmetric across axes).
* Update src/slic3r/GUI/Tab.cpp
Co-authored-by: Rodrigo Faselli <162915171+RF47@users.noreply.github.com>
* Address review feedback (Copilot + @RF47)
- Fill.cpp: gate params.gyroid_optimized on (params.pattern == ipGyroid)
so non-gyroid surfaces don't differ in SurfaceFillParams by an
irrelevant flag (would unnecessarily split fill batching).
[Copilot suggestion, RF47 confirmed correct]
- PrintConfig.cpp: drop "amplitude" from the tooltip; only wavelength
is parameterized (the marching-squares iso=0 extraction is invariant
to a uniform field scale, so amplitude has no effect).
- FillBase.hpp: shorten gyroid_optimized comment to match the actual
carried state (no amplitude term).
- FillGyroid.cpp: shorten the marchsq namespace comment block; the
ODR concern was overstated (FillTpmsFK uses the same pattern fine).
* Drop redundant marchsq bb expansion (Copilot)
bb is already offset by 10 * scale_(spacing) above for edge-artifact
margin; the second offset on bb_field doubled the raster area for no
geometric benefit and hurt CPU time on large parts.
* Update src/slic3r/GUI/Tab.cpp

* Fix density mismatch + rename to Z-buckling bias optimization
Issue (per @ianalexis): at the same sparse_infill_density setting,
the optimized branch produced denser fill than standard. Verified via
Python sim (sim_gyroid_compare.py) using marching squares on the
implicit field across multiple z slices.
Root cause: the omega formula was inverted from the buckling-physics
intent. The naive sqrt(density_adj) factor produced omega < 1 at
typical print densities (10-30%), which LENGTHENED the Z wavelength
instead of shortening it -- net loss in both mass and strength.
Fix:
- compute_omega_factor: invert to sqrt(1 / density_adj), clamp to
[1.0, 2.0]. Now omega = 2.0 at low density (long strands need
most help) and clamps to 1.0 above ~30% density (no-op, since
standard gyroid is already short enough).
- Remove the cbrt(omega) period compensation. Empirically (sim
table embedded in FillGyroid.cpp comment) the inverted formula
keeps line length per area at ~1.000 of standard across all
densities with no period scaling needed.
Predicted gains (sim, Z-axis Euler buckling proxy):
density line/std strength/std
10% 1.000 2.84x
15% 1.000 1.89x
20% 1.000 1.42x
30%+ 1.000 1.00x (no-op)
Rename per @ianalexis: "Optimize gyroid wave" oversells (now no-op
above 30% density and Z-only). Renamed user-facing label to
"Z-buckling bias optimization (experimental)" with updated tooltip
that scopes to vertical compression and discloses the density cutoff.
Internal config key (gyroid_optimized) unchanged for diff size.
Real-world Instron compression tests at Brown's Prince Lab to follow.

GridCellSupportEditor::DoActivate dereferenced
grid->GetSelectedBlocks().begin() without checking against end(). In
wxWidgets 3.1.5 that range always contained at least one block; in 3.3.2
it is empty after the user deselects, and the dereference crashes inside
wxGridBlockCoords::GetLeftCol().
Fall back to the (row, col) that triggered activation when the selection
is empty, so the existing single-cell branch handles it. While here,
drop a dead local_table cast that was never read.
Fix macOS orcaslicer:// deep links after wxWidgets 3.3.2 upgrade
Install an OrcaSlicer-owned kAEGetURL Apple Event handler from
on_init_inner(). The wxWidgets 3.3.2 handler registered in
applicationWillFinishLaunching: stopped delivering URL events to
GUI_App::MacOpenURL on macOS (#13119), so links from Printables /
Thingiverse opened a blank project instead of importing the model.
Registering our own handler late in startup is last-writer-wins on
NSAppleEventManager and routes back to the existing MacOpenURL ->
start_download path, restoring the pre-upgrade behavior without
touching wxWidgets.

Use glBlendFuncSeparate in GLTexture::render_sub_texture so destination
alpha stays at 1.0. The Wayland compositor honors framebuffer alpha for window compositing; the previous straight-alpha blend reduced dst alpha
at anti-aliased icon edges, making them semi-transparent against the
desktop. RGB blending is unchanged, so X11/Windows/macOS are unaffected.
Delay opening the object-list filament dropdown on wxGTK until the editor
window is mapped, avoiding popup creation without a valid native toplevel.
Also set the GTK transient parent for dropdown popups created from data-view
cell editors.
