Adds CadFeatureType::Mirror: reflect a target body about a plane using
gp_Trsf::SetMirror + BRepBuilderAPI_Transform. BooleanMode::New keeps the
mirrored copy as its own body (mirror_keep_original decides whether the
source survives); BooleanMode::Add fuses it back into the source, so an
overlapping mirror does not double-count volume.
Serialization: mirror_keep_original is appended at the very end of both
CadFeature::save and load (append-only contract). The mirror plane reuses
the existing `plane` member and the body selector reuses `target_body`,
as Cut already does. Golden fixture regenerated at the current
SNAPORCA_CAD_RECIPE_VERSION = 2; the existing field-value assertions all
still pass unchanged, and the reorder tripwire was re-verified after
regeneration (swapping draft_face/draft_angle in `load` alone still
fails the golden test).
Tests assert analytic values: mirrored volumes equal (8000 each) with the
reflected centroid, Add on a non-overlapping asymmetric body gives exactly
2x volume, Add across an intersecting plane gives strictly less than 2x,
and an invalid body index fails cleanly with a non-empty error.

# Description
Adding optional flag for enabling console logging introduced in #14439.
Console logging not working with LLDB-DAP on VSCode as per #14897
Code changes won't fix this because it is a LLDB-DAP issue documented in
#14909
Use flag `-DUSE_SLIC3R_CONSOLE_LOG=ON` or `-DUSE_SLIC3R_CONSOLE_LOG=OFF`
to enable/disable it.
Alternatively in you VSCode's settings.json,
```
"cmake.configureSettings": {
"USE_SLIC3R_CONSOLE_LOG": "OFF"
}

# Description
Fixes some bugs reported by users and the community
# Fix 1: Latest Version
If the user updates the plugin version on OrcaCloud without a changelog,
the latest version shown on OrcaSlicer won't be accurate.
## Issue
OrcaSlicer uses the changelog returned by OrcaCloud backend as the
source of truth, even though we query a latest version from the backend
as well. The changelog only consists of version entries that have
changelogs so if the latest one, e.g. 1.2.0 has no changelog, but 1.1.0
has, the latest version will be interpreted as 1.1.0.
## Fix
Don't use the changelog for version tracking, just use it for the
plugins dialog changelog tab.
# Fix 2: Host theme script / window.orca bridge leaks into cross-origin
child iframes
If a plugin's embedded app renders its own `<iframe>` (its real
catalog/dashboard UI, or a third-party auth/payment widget), that child
document also gets, uninvited: the host theme `<style>` block fighting
whatever CSS the child page already defines.
## Issue
OrcaSlicer injects host themed scripts and window.orca bridge into every
page, potentially breaking any cross origin child frames or `<iframes>`
in general.
## Fix
Only inject top level frames by checking `if (window.top !==
window.self) return;`.
# Fix 3: Transferring Slicing Pipeline Plugin config when switching
printers (#14832)
Select an entry in the Process tab's "Slicing Pipeline Plugin" picker,
switch the active printer preset, then click **Transfer** in the
"modified settings" dialog — OrcaSlicer crashes immediately and
repeatably. Changing other settings (e.g. a single scalar option) does
not reproduce it; only this picker does.
## Issue
`slicing_pipeline_plugin` is a vector option (`coStrings`) with an empty
default. `deep_diff` diffs vector options per-index, so selecting a
plugin produced a `"slicing_pipeline_plugin#0"` dirty key instead of a
plain one. Unlike genuine per-extruder options, this key wasn't caught
by the printer-switch filter that discards stale per-extruder changes,
so it got cached and replayed through `ConfigBase::apply_only`'s
`'#'`-indexed branch, which calls `ConfigOptionVector::set_at()` on the
freshly-reloaded (and still empty) destination vector. `set_at()`'s only
empty-vector guard is an `assert()`, which is compiled out of Release
builds, so it dereferences `values.front()` on an empty vector —
undefined behavior, matching the reported ACCESS_VIOLATION.
## Fix
Treat `slicing_pipeline_plugin` as a single atomic value in `deep_diff`
(`Preset.cpp`), same as `printable_area`/`thumbnails`/etc.,
since it isn't actually per-extruder data. It's now diffed and replayed
as a whole option (`ConfigOptionVector::set()`, a plain vector
assignment) instead of the index-based `set_at()` path — removing the
crash unconditionally, regardless of whether the two printers share the
same extruder configuration.
# Fix 4: Stale .whl cache
After a .whl was loaded once, if at runtime, the .whl is replaced with a
new one, the plugin system will use the stale .whl cache.
## Fix
Added an option in the context menu to Reload or Delete Cache and Reload
for locally installed plugins. The assumption here is that users
shouldn't be modify cloud plugins, and if they want to develop on a
subscribed cloud plugin, they should create a local copy of it.

[How to Download Pull Requests Artifacts for
Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
Selection failures on a real desktop kept looking identical from the UI
whether the ray missed the solid, the click was rejected as a drag, or the
press never reached the tool at all. The status line added in edb1adbfa3
reports WHICH body/face was picked, so it distinguishes "picked" from
"silence" and nothing finer -- not enough to tell those three apart.
This narrates the whole press -> release -> ray path on stderr, one distinct
line per failure mode:
down x= y= the press reached the tool
up with no pending press the press was eaten upstream
up ... drift=N / rejected the click-vs-drag threshold decided
ray tris=N -> body= face= t= the ray reached the solid (or missed)
no solid data (bodies= mesh=) the pick pointers were never wired
Gated on getenv("SNAPORCA_PICK_TRACE"), cached in a function-local static,
so a normal build pays one load and prints nothing. It ships enabled-on-
demand because the failing environment is a real X session with a real
mouse, which the headless rig cannot reproduce.
First use retired a wrong theory of my own: the trace showed drift=0 on
three consecutive picks, so the widened threshold in edb1adbfa3 was not
what fixed anything. The reported symptom is best explained by a stale
pre-orcawidgets binary left running alongside the current one.

## Problem
On H2C (carousel) printers, the wipe tower purge volume calculation in
`_make_wipe_tower()` tracks filament state **per-extruder** (2 slots).
Since H2C has up to 7 carousel nozzle slots on a single extruder, all
filaments sharing that extruder are collapsed into one tracking slot.
This causes:
Test:
[5cubes.3mf.zip](https://github.com/user-attachments/files/30092551/5cubes.3mf.zip)
- **Massive redundant AMS flushing** every filament change on the
carousel triggers a full purge against the "previous" filament, even
when the target nozzle slot already has the correct filament loaded
- **60.9g total weight** instead of ~17g (**3.5× material waste**)
- **3h09m print time** instead of ~1h57m (**60% longer**)
## Root Cause
The code uses `nozzle_cur_filament_ids[extruder_id]` (a 2-element array)
to track which filament was last used for each extruder. BambuStudio
uses `NozzleStatusRecorder`, which tracks per `group_id` (physical
carousel slot 0..6).
## Changes
| File | Change |
|---|---|
| `Print.cpp` | Replace `nozzle_cur_filament_ids` with
`NozzleStatusRecorder`. Use `get_nozzle_for_filament()` to resolve the
physical carousel slot per layer. Select `filament_prime_volume_nc` for
nozzle changes, `filament_prime_volume` for filament changes. |
| `PrintConfig.hpp` | Add `ConfigOptionFloats filament_prime_volume`
(per-filament EC prime volume, missing from upstream but present in BBS
and H2C profiles) |
| `PrintConfig.cpp` | Register `filament_prime_volume` with default
45mm³ (matching BBS) |
| `Preset.cpp` | Add `filament_prime_volume` to preset keys |
Also includes `tests/compare_analyzer/` - two standalone Python tools
for G-code slice comparison and temperature timeline analysis (stdlib
only, no dependencies).
## Test Results (5-color H2C Hybrid print, same 3mf project)
| Metric | Upstream (broken) | **Fixed** | BBS (reference) |
|---|---|---|---|
| **Total weight** | 60.90g | **16.20g** ✅ | 17.47g |
| **Print time** | 3h09m | **1h57m** ✅ | 1h51m |
| **Filament changes** | 105 | 105 | 140 |
| **Tool changes** | 35 | 35 | 35 |
| **Critical discrepancies vs BBS** | ⚠️ YES | ✅ None | — |
## Analysis Tools (`tests/compare_analyzer/`)
Two standalone Python tools (stdlib only, no dependencies) for deep
G-code comparison:
- **`compare_slices.py`** - comprehensive .3mf slice comparison:
filament usage, nozzle mapping, tool change sequences, prime tower
analysis, temperature timeline, retract parameters, and automatic
critical discrepancy detection (weight/time anomalies)
- **`show_temp_plot.py`** - interactive HTML temperature timeline
plotter for visualising heater profiles during multi-nozzle prints
(supports single-file and side-by-side comparison)
Usage:
```bash
python3 tests/compare_analyzer/compare_slices.py file1.3mf file2.3mf --labels "Upstream" "Fixed"
python3 tests/compare_analyzer/show_temp_plot.py file1.3mf file2.3mf
```

## Compatibility
Safe for non-carousel printers: when each extruder has a single nozzle,
`group_id == extruder_id`, so `NozzleStatusRecorder` behaves identically
to the original per-extruder tracking. The `filament_prime_volume`
default (45mm³) matches the existing global `prime_volume` default.
## Reference

Adopt BambuStudio's load_last_machine (cloud machines only, remembered
machine preferred) and port record_user_last_machine /
get_user_last_machine. Orca's version auto-connected an arbitrary LAN
printer, starting an unrequested connection that the user's first
printer switch tore down mid-flight, which the 02.08 plugin's connect
worker does not survive. This also caused the 100% crash-on-relaunch
loop: the crashed-on printer was auto-connected at startup, so
re-selecting it always hit the same-machine disconnect+reconnect path.
* fix: constrain PA_Line calibration bounding box to model geometry
- PA_Line bounding box now uses actual model convex hull for X constraint instead of full printable area
- Skip EXCLUDE_OBJECT_DEFINE for PA_Line mode (single object, no exclusion needed)
- Add tool config files to .gitignore
* modified: .gitignore
* fix: add gcode type annotations and fix box height in PA line calibration
- Label calibration segments with appropriate TYPE comments (Outer wall, Bottom surface, Top surface, Custom) for proper gcode processing
- Fix bounding box height calculation to account for z_offset
- Add LAYER_CHANGE and HEIGHT comments for multi-layer numbering display
* fix: lock PA_Line bounding box X to bed centre instead of model hull
* Added extra TYPE to ensure text/numbers/glyphs are labelled correctly
` gcode << ";TYPE:Outer wall\n"; `
* Remove hardcoded Perl path in OpenSSL.cmake
Remove hardcoded Perl path for Windows configuration.
* Add cross compilation support for Windows in OpenSSL.cmake
* Remove unnecessary blank line in OpenSSL.cmake
* Set perl config command back to variable
Accidentally uploaded version with hardcoded path for my local environment
* whitespace adjustment in previous
* removed personal .gitignore config
Remove specific files and directories from .gitignore.
* Fix box height parameter in DrawBoxOptArgs
Update DrawBoxOptArgs to use `m_height_layer` instead of `m_height_layer*2+z_offset`. This isn't a Z coordinate, it's a layer height
* Replace hardcoded extrusion type with call to `GCodeProcessor::reserved_tag` Etags
* Get pa_line bounding box from actual calibration variables
Updated calibration line bounding box calculation to use actual geometry for X bounds, using a fake call to generate the calibration pattern.
This will accurately get the size of the calibration pattern, massively reducing wasted time from bed mesh probing.
* Implement print_extents method in CalibPressureAdvanceLine
Add print_extents method to calculate bounding box extents based on bed dimensions.
* Declare print_extents method in CalibPressureAdvanceLine
Added print_extents method to return X-bounds of the pattern.
* Fixed whitespace issues
* Adjust print_extents to account for delta printers
Check if the printer is delta layout and adjust bed dimensions if so.
Used code from `CalibPressureAdvanceLine::generate_test`
* Added semicolons to reserved tags
Didn't realise etags wouldn't add semicolon - added these
* only include number list in bounding box if number list is used

The LeftUp pick discarded anything moving more than 4 px total since the
press. A hand-held mouse drifts that much during an ordinary click, so
real clicks were thrown away as drags and it read as "selection does not
work". Use 8 px per axis, GTK's own drag threshold.
Also report the pick on the status line (body / face / edge). A solid
pick previously set no text at all, so its only feedback was the viewport
highlight, and a pick that registers but draws faintly looked identical
to one that never fired.
DesignSketchTool.cpp copied verbatim (identical between the forks apart
from this change). DesignPanel.cpp took the status hunk only, since this
fork keeps mainline's Item-based DropDown in feat_dropdown/ToolFlyout.
Not confirmed on hardware yet, on either fork; this fork remains
uncompiled (needs Eigen 5.0.1).

- WipeTower: use filament_ramming_volumetric_speed(_nc) for ramming, falling back to
max_vol_speed only when nil; gate precool temps on enable_pre_heating
- ToolOrderUtils: disable the inter-layer forecast in the per-nozzle base reorder so
H2D/H2C ordering is unchanged
- PrintConfig: stop stripping filament_prime_volume in handle_legacy; document that
prime_volume drives the Type2 wipe tower and filament_prime_volume the Type1 one
- GCodeProcessor: exclude post-print end-gcode M400 dwells from the M73 estimate and
drop the dead air-filtration state
- Trim verbose BambuStudio source-location comments across the port
Ports snaporca-cad c741fb9677.
SketchInlineEditor::open() clamped its position with
wxGetClientDisplayRect(), which describes only the PRIMARY monitor. On a
multi-head desktop (the reporting machine runs 5760x1080 across screens
at +0, +1920 and +3840) a field anchored on the left or right screen was
clamped onto the middle one and left invisible, while m_awaiting_length
made the sketch tool consume every mouse event until it was answered:
orbit and pan died after any sketch, with Enter the only way out. Clamp
to the display the anchor is actually on instead.
Also let drags and the wheel through that freeze, so a field that lands
somewhere unexpected degrades to odd placement rather than a dead
viewport.
Both files were byte-identical between the forks apart from this change,
so they are copied verbatim. Verified on the snaporca side by the user;
this fork is still uncompiled (needs Eigen 5.0.1, which the available
deps image does not provide).
