libslic3r_gui calls webkit_* directly, and OrcaSlicer.cpp and libspnav
call Xlib, but both libraries were only linked when FLATPAK was set.
The default build links because the bundled static wxWidgets lists
them in wx-config. A shared wxWidgets does not, so any build against
one, like the Flatpak build or a distro package, fails with undefined
webkit_* and X* symbols.
Pressure advance, adaptive pressure advance and its model can now take a
different value for each extruder variant of a filament, such as Standard and
High Flow nozzles, like the other per-variant filament settings. Projects
saved with one value per filament apply it to every variant of that filament,
and the addnorth BBL filaments in the Orca Filament Library are updated to the
per-variant layout.
* Validate OBJ Texture-Coordinate Indices
load_obj read the texture coordinates of a face without checking the
vt index, so a face referencing a vt past the end of the list read out
of bounds and crashed, and a face vertex with no vt read index -1.
Out-of-range or missing indices now fall back to a zero UV. The face
keeps its entry in the per-face UV list, so the following faces stay
aligned, and the geometry loads as before.
Negative (relative) vt indices were also rebased by dividing the float
count by 3, but each vt stores two floats.
* Reject DRC Meshes Without Positions or with Invalid Face Indices
load_drc dereferenced the POSITION attribute without checking that the
mesh has one, and trusted the decoded face indices, which the Draco
decoder does not check against the point count. Both now fail the load
cleanly. A failed vertex conversion is treated the same way.
The libslic3r tests link Draco so they can encode the malformed meshes
in-test.
* Keep OBJ Texture Coordinates That Carry a W Component
The vt parser stopped reading the optional third component when texture
coordinates were cut down to u and v, but the check that nothing is left
on the line stayed. A legal "vt u v w" line was therefore rejected and
silently dropped, shifting every later texture index. The w component is
parsed again and discarded.
The texture coordinate stride is now a named constant, OBJ_TEXCOORD_LENGTH,
used by the parser and the importer, so the relative-index rebase cannot
drift from the storage layout again.
# Description
The Ender-3 V3 SE machine start G-code performs its purge using
absolute-style extrusion positions:
```gcode
G1 ... E15
G1 ... E30
```
However, the machine start G-code does not explicitly initialize the
positioning or extrusion mode before these commands.
OrcaSlicer emits the printer's custom `machine_start_gcode` before its
own generated `G90` / `M82` or `M83` preamble. This means the purge can
inherit the extrusion mode left active by the printer.
For example, if `M83` relative extrusion is still active, such as after
a cancelled print where normal end G-code was not executed:
- `E15` extrudes 15 mm
- `E30` extrudes another 30 mm
Instead of the intended 15 mm followed by another 15 mm.
This change explicitly adds:
```gcode
G90 ;Absolute positioning
M82 ;Absolute extrusion mode
```
before the purge sequence so startup behaviour is deterministic and does
not depend on inherited printer state.
The change is applied consistently to all Ender-3 V3 SE nozzle variants:
- 0.2 mm
- 0.4 mm
- 0.6 mm
- 0.8 mm
No print speeds, temperatures, retraction values, machine limits, or
other profile settings are changed.
# Screenshots/Recordings/Graphs
Not applicable. This is a machine start G-code profile fix.
## Tests
- Confirmed all four Ender-3 V3 SE profiles use the same `E15` / `E30`
purge sequence.
- Confirmed the current profiles do not explicitly issue `G90`, `M82`,
or `M83` before that purge.
- Confirmed OrcaSlicer emits `machine_start_gcode` before its generated
positioning/extrusion-mode preamble.
- Verified the modified JSON for all four machine profiles parses
successfully.
- Verified the added commands make the purge explicitly use absolute XYZ
and absolute extrusion state.
# Description
Follow-up to #15950, where a `filename_format` using
`initial_no_support_extruder` shipped broken because the profile
validator's slice sweep never expands `filename_format`. The sweep now
expands every custom G-code and `filename_format` text shipped in any
system profile. Each printer's slice also fires the pause, template
custom G-code and clumping-detection hooks and names the output file,
and the first printer shipping a `printing_by_object_gcode` also slices
by object. Beyond each printer's default process and filament, every
compatible system process and filament carrying a template text no
earlier slice has expanded is sliced once, which takes the sweep from
1,110 to 1,248 slices (about 49 s locally, up from 43 s). While the
sweep runs, the placeholder parser also resolves variable names inside
`{if}` branches a slice does not take, so one expansion checks every
branch.
The stricter sweep found two profile bugs, fixed here: the Anycubic
Kobra X filament change G-code carried an unreachable block reading
variables only Anycubic's own slicer defines, and the Wanhao France D12
template custom G-code had an unterminated `{if}`, so adding a template
custom G-code on those printers failed the slice. It also fixes a parser
bug where a declaration such as `{local a = layer_height + 1}` failed to
parse inside a branch that is not taken.
No change to slicing output for templates that already worked: the
untaken-branch check is enabled only by the validator's slice mode, and
the parser fix only lets previously rejected templates parse.

## Tests
New placeholder-parser cases cover the parse fix and the untaken-branch
check: off by default it changes nothing; on, it rejects undefined names
in branches not taken, accepts names declared there, and leaves boolean
expressions (compatibility conditions) alone. The full sweep passes on
all system profiles, and planting an undefined variable in an untaken
branch of a printer's start G-code, of a non-default filament's start
G-code or of a non-default process's `filename_format`, or reverting
#15950, each fails it and names the preset. `scripts/check_profile.sh`,
`libslic3r_tests` and `fff_print_tests` pass.

[How to Download Pull Requests Artifacts for
Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
The 3MF importers read XML entries into a single expat buffer whose size is
an int, while the archive extraction used the entry's 64-bit declared size.
The two could disagree for entries declaring more than INT_MAX bytes.
Reject such entries before allocating, and use one size for the buffer, the
extraction and the parse. This applies to the BBS importer, the PrusaSlicer
importer and the PrusaSlicer fingerprint probe. The load now fails with an
error instead.
* Reject 3MF Plate IDs Below 1 Instead of Indexing Before the Plate List
The plate importer copied each plater_id from model_settings.config into the
1-based plate list after checking only the upper bound, so plater_id="0"
wrote to plate_data_list[-1] and crashed on load. Both copy sites now reject
ids below 1 with the same "invalid plate index" error already used for ids
past the end.
* Drop Malformed 3MF Paint Data Instead of Reading Past the Bitstream
Painted facets are decoded from a bitstream a nibble at a time with no bound
check, so a truncated or corrupt paint string in a 3MF (for example split
codes with no children behind them) read past the end and crashed on load and
slice. A one- or two-side split naming side 3 also indexed past the triangle's
vertices.
Every nibble read now goes through a bounds-checked reader. Loading validates
each triangle's tree and drops a malformed one with a warning, so the stored
data, used extruder states and later decoding all agree. deserialize() also
unwinds and clears any triangle whose tree is incomplete or malformed, and
has_facets() stops at a truncated triangle. Valid streams decode unchanged.
* Sanitize Server-Supplied Download File Names
The URL downloader used the file name from the Content-Disposition header
as given, without the cleaning and unused-name search applied to the
URL-derived name.
Reduce the header name to a sanitized base name with the new
sanitize_file_basename helper, which splits on both path separators and
rejects names made only of dots and spaces. Run the result through the
same unused-name search as the URL-derived name, now shared in
find_unused_filename, and fall back to the URL-derived name when nothing
usable remains.
* Sanitize Download Names Before Choosing an Unused One
The unused-name search probed the name as given and sanitized the
result afterwards, so a name whose special characters are replaced
could be mapped onto a file that already exists.
Move the search into libslic3r as find_unused_filename, sanitize first
and probe the name that is actually written. The download marker path
is shared through download_marker_path. Restore the last tried name in
the error reported when no free name is found, and cover the search
with unit tests.
* Keep Downloads on an Unused Name Until They Complete
When the server supplied the name, the download marker stayed under the
URL-derived name, so the adopted name was not reserved against other
downloads. The final rename also replaced any file that took the name
while the download ran.
Move the marker to the adopted name before any data is written, and
check the name again right before the final rename, picking the next
free name if it is taken by then.
* Sanitize the File Name of Model Import Links
The model import took the file name from the link as given and only
avoided an existing file with a substring match on the folder listing.
Reduce the name to a sanitized base name, falling back to untitled.3mf,
choose the name with the shared unused-name search, and check it again
before the final rename.
* Handle Filesystem Errors When Finishing a Model Import Download
Choosing the final name and moving the downloaded project into place
could throw from inside the download callback. Any such error now removes
the temporary file and reports the existing import failure message.
* Non-crossing infill optimization
* test triangles
* test grid
* cleaning
* Align and clip rectilinear infill paths
Generate infill coverage in the pattern's local frame, rotate triangular patterns by layer, and clip centerlines to the surface vicinity. Start closed outlines outside the surface so clipping splits them cleanly.
* Update test_fill.cpp
* Update multiline-infill.md

# Description
Extruder variants (Standard, High Flow, extra high flow) now work on any
printer. Any vendor profile can declare them, and a multi-variant
filament picks up the right variant on every printer. In the sidebar,
users can switch the printer variant and set the nozzle volume type of
each extruder on multi-extruder printers. This also fixes a later
filament printing at the first filament's temperature on a P1S or X1C
with a High Flow nozzle. The profile checks now reject variant arrays of
the wrong size and outdated variant strings. Every shipped vendor
profile passes them, and the orca-profiles skill documents the rules.
Slicing output changes only where the wrong variant was used before.

The block ran only when flush_length_4 is -1392 and read ace_t_box_vector / ace_t_slot_vector, which only Anycubic's own slicer defines. It emitted comments only, so the printed G-code is unchanged.

This PR fixes some problems with the current profiles for Blocks
printers
- **Fix**: start gcode for the Blocks 0.6mm RF50 printer where the start
gcode command had no newline separation on two commands so they were
concatenated and would make printing fail.
- **Added**: multi material plates selection for the RF50 printers,
right now only textured PEI and smooth high temp plates are available,
but in the future more to come.
- **Naming consistancy** for Blocks Pro S100 processes and filaments,
target labels used bare `@Blocks` while RD50 and RF50 used
`@Blocks_RD50` and `@Blocks_RF50`. Renamed Pro S100 to
`@Blocks_Pro_S100` to match the structure.
- **Filament restructure**: replaced Blocks tuned-generic filaments
(e.g. `Generic PLA @Blocks`) with real Blocks-branded filaments. One for
each printer model. Every material keeps the same coverage we already
had.
- **Fix**: `sparse_infill_pattern` was misspelled `sparse_infill_patter`
on 13 `@Blocks_RF50` process presets. Harmless due to inheritances but
fixed non the less.
- **Fix**: `Blocks RD50 V2 0.4 nozzle.json` was missing
`printer_variant`.
- **Normalize** all Blocks profiles to standard formatting (tab
indentation, key order) and bumped `Blocks.json` version.
- **RF50 retraction length** increased on all RF50 machines.
## Tests
- [x] `orca_profile_tool.py check --vendor Blocks` - clean
- [x] `orca_profile_tool.py check` - clean
- [x] `normalize` / `generate-id` / `update-index --dry-run` — fully
settled, no pending changes
- [x] `check_profile.sh --vendor Blocks` → `profile_tool` check — passes
- [ ] `validate_system` / `validate_slice` /
`validate_filament_subtypes` / `validate_custom` —
could not run locally (dev host's glibc 2.36 is older than the nightly
validator binary's
required 2.38); needs CI or a compatible host
- [x] In-app confirmation that the Blocks bundle loads

The segments come in print order, bottom layer first, which seen from above is back to
front: every hidden fragment is shaded before the one that covers it, and on an integrated
GPU that overdraw is most of the frame. Drawing the instances last to first whenever the
camera looks down lets the depth test reject the hidden fragments instead. Side views and
views from below keep the print order, and the shadow-caster pass is unchanged.

Avoid calling Print::output_filename() when a slice is canceled or
fails, since unresolved filename placeholders can throw before G-code
export completes.
Instead, we should use the model name in ctx.name and the stable model
ID in ctx.id, consistently across slice and G-code export events.

Fix#15885
Fix size_t/%d mismatch in MsgDialog button keys
`m_buttons.size()` is a `size_t`, which does not match the `%d` conversion in
printf-style variadics. Build the key with `std::to_string` instead; exact
for any size_t, no behavior change for realistic counts.

Guard the smooth-normals preference read when CLI thumbnail generation initializes geometry without a wx application. Use the existing flat-normal path in that case and preserve GUI preferences.
Use DPI-aware 20 DIP vertical scrolling for general-purpose GUI
scroll areas.
Keep list-based views aligned to their item height so one wheel increment follows the visible row rhythm.
This makes Preferences and other dialogs scroll consistently across
Windows DPI settings.
get_dpi_for_window's pre-8.1 fallback and get_font_list_by_enumeration
both called GetDC without a matching ReleaseDC, leaking a GDI handle
each call. get_dpi_for_window runs on every mouse-move over the 3D
viewport, so the leak exhausts the per-process GDI handle limit and
hangs the app within minutes on Windows 7/8.
