# 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.

Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
## 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
BambuStudio `Print.cpp` `_make_wipe_tower()` L3341-3392 -
`NozzleStatusRecorder` pattern.
# Description
Support the 02.08.01 network plug-in and resync the Bambu device
workflow
Brings the Bambu network plug-in up to the 02.08.01 series and reworks
the plug-in
lifecycle around it (ABI gating, OTA install, hot reload), then catches
the device and
monitor side up to what that plug-in and current firmware expose — AMS
mapping, send-flow
checks, print options, and the device status pages.
**Included:**
_Network plug-in_
- Default to the 02.08.01 series and bind its new ABI symbols; bump the
reported
`SLIC3R_VERSION` to 02.08.01.55
- Gate loading to ABI-compatible `AA.BB.CC` series, and store plug-in
identity by series
rather than by exact build
- Fix the OTA update flow: install immediately, hot-reload without a
restart, and destroy
the agent before unloading the DLL
- Version selector lists same-series OTA builds newest first, with
dynamic
"(Latest)" / "(installed)" labels
- Restart printer discovery and reload saved LAN printers after a hot
reload
_Device layer_
- Move axis, calibration, chamber, status and upgrade handling into
DeviceCore; drop the
transitional shims
- Resync the DeviceCore state models, accessory firmware versions,
cold-pull state and
filament checks
_Device UI_
- Resync the AMS control/item widgets, device dialogs, device tab
widgets and status pages
- Add the AMS best-position popup, filament-change stop button, hub
version row and HMS
fallback
- Device error dialog: print-failure snapshot, purification and
don't-remind actions
_Send flow_
- Resync the send flow and port the remaining pre-send checks and
advisories
- Warn when a filament will switch extruders mid-print; block TPU on the
l
without firmware support (O1D/O1E)
- Map switch-bound AMS trays to both extruders and show combined nozzle
mapping
- Add the shared-PA-profile toggle
_Print options / timelapse_
- Restructure DevPrintOptions around a detection-option map and parse
the
bits on the live push path
- Add firmware print-option toggles, plus timelapse storage-location
selection with a
free-space check
_Fixes_
- Inverted MQTT jog on i3-architecture printers, plus assorted popup,
mapping and
status-parse defects
_Tests_
- New Catch2 coverage for network version selection and device filament
mapping
Printers that don't advertise the new capabilities are unaffected —
every added behavior is
gated on a firmware or plug-in capability flag, and the only profile
chang
`support_print_check_firmware_for_tpu_left` to O1D/O1E.

[How to Download Pull Requests Artifacts for
Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
The stored plug-in identity is now the AA.BB.CC series (matching BambuStudio)
rather than the full build version, so the meaningless 4th build digit stops
driving config, the whitelist, filenames, and the version selector. This fixes
the macOS "can't switch to an older build" bug: the cloud endpoint is
series-keyed and only ever serves a series' newest build, so downgrade-by-
download was impossible and the download silently adopted the latest.
A startup migration normalizes an existing full-version config and file name to
the series form with no re-download, the loader resolves a bare series to the
newest same-series build on disk, and user-provided custom-named plug-ins
(libbambu_networking_02.08.01_custom.*) are still enumerated and loaded.
Discovered builds were inserted positionally behind the whitelist entry they
anchored to, so an OTA-installed 02.08.01.53 listed below 02.08.01.52. The list
is now built by appending and sorting once, which also drops the per-entry
insertion scans.
"(installed)" tested whether the library was present on disk, so it marked every
version ever selected - switching leaves the previous library in place. The flag
is now is_loaded, resolved against the plug-in actually loaded, and the two
combo populators share one label helper.
- Allow mapping to EMPTY trays only from the multi-machine send page and keep
both panels pickable in the LEFT_AND_RIGHT view
- Guard the error-dialog cloud snapshot against stale callbacks and fall back
to the local illustration on timeout
- Parse the ipcam storage-check ack and axis/chamber pushes defensively
- Strip fan-control telemetry, initialize the upgrade error code, restore the
.json filter in the model-id scan
- Fix best-position popup tray lookup, gradient placement, and colour-list
ownership
- Cover switch binding sets and invalid-track transients in DevMapping tests
Trim the version whitelist to the latest series plus the pinned legacy build,
and reject out-of-series configured versions at startup, compatibility check,
and load failure - falling back to the latest installed build or the clean
re-download flow so the config never keeps pointing at an unsupported build.
* Block plugins from reading or writing app config and cloud credentials
Add a denied-filename registry to the plugin audit sandbox, seeded with OrcaSlicer's config (.conf/.ini) and the cloud refresh-token file. The deny is checked above the loading-mode read exemption and the allowed roots, so a plugin cannot reach these files even though they sit inside data_dir(), which is itself an allowed root. Case-insensitive prefix matching also covers the .bak/.tmp companions that hold the same data, and os.rename/os.remove are hooked alongside open so the files cannot be deleted or clobbered either.
# Description
Use Space to trigger a new **speed dial**, which allows users to run
**app actions**. The only app actions implemented currently are python
plugin scripts.
## Notes
- Only toggleable in the Prepare (3D) view. Press Space, type to filter,
Enter or double-click to run.
- Focuses on search bar automatically
- Frecency-sorted (run count + recency) with alphabetical fallback (C++
computes)
- Pin actions as favourites and they will show on the top favourites
bar. Done through star icon on each row.
- Script plugins have no icon art yet, so tiles show a collision-aware
monogram: the capability's initial, escalating only when names collide -
prepend the package initial, then add an ordinal - so same-named actions
from different plugins stay distinguishable.
- E.g., capability Bravo from plugin Alpha normally shows just B. If
another action's name also starts with B, they disambiguate by
prepending the package initial (Alpha -> AB). If two still collide on
both initials (both AB), they become AB1 and AB2.
- "Run X?" confirm with a per-plugin "don't ask again" scope, owned
C++-side; suppression persists.
- Persistence (`speed_dial` AppConfig section): `favourite_actions`
(ordered id list) + per-action `stats` + `ask_suppressed`.
- Example of shape in data_dir:
```json
{
"speed_dial": {
"ask_suppressed": "[\"9b12aa079924bbc4\"]",
"favourite_actions": "[\"ccfdf8b9e492b624\",\"9b12aa079924bbc4\",\"b7abfa67626248e4\"]",
"stats": "{\"31d9d129a616a8b7\":{\"count\":4,\"last\":1783924989},\"53ec17d430634f62\":{\"count\":3,\"last\":1783939329},\"9b12aa079924bbc4\":{\"count\":5,\"last\":1783924981},\"9f2cb0d3ca56a87c\":{\"count\":1,\"last\":1783668370},\"b7abfa67626248e4\":{\"count\":4,\"last\":1783939325},\"f93469da14248128\":{\"count\":3,\"last\":1783939337}}"
},
}

## Tests
- **Web layer (green):** node-vm logic test `test-speeddial-logic.js`
covers `filterActions`, `visibleFavourites` (incl. the runnable guard),
`selectedActionId`, `resultCountText`, `actionLabel`, `tileCode`,
`nextSel`, and payload seeding - pure helpers, DOM-free.
- **Backend:** `ActionRegistry` FNV-1a id golden-vector Catch2 test
(`test_speed_dial_action_id`) pins the hash; the registry was verified
by fresh-context review including a threading fix (`run()` operates on a
stack copy so a queued refresh can't reallocate the action vector
mid-run).
- **Manual (all passing):**
- Space opens the dial in Prepare only; no regression to existing
Prepare-tab keys or the Plugins dialog.
- Search auto-focuses; typing filters live; a freshly-run action rises
in the frecency order.
- Up jumps to the favourites bar, Down into the list, Alt+1..9 hits
favourites; Enter and double-click run the highlighted action.
- Star pins/unpins an action; favourites persist across an app restart.
- "Run X?" confirm with per-plugin "don't ask again" is respected on
later runs.
- The `?` shortcuts dialog shows the Space row.
- Verified in both light and dark themes.
## Known Issues
When there are no actions, plugins, or scripts, the search bar will show
"Search 0 actions". This is bad UX. One alternative considered was to
show a call to action, for example "Please load plugin scripts so that
they appear here".
However, this is ultimately not implemented, as eventually it is not
expected that actions will be empty. The action registry will not be
expected to be empty because we will include in-app actions such as
opening dialogues or other app actions.

[How to Download Pull Requests Artifacts for
Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
Adapt the speed dial's ActionRegistry to the collapsed
get_plugin_capability(PluginCapabilityId) overload, and restore the
script success/skipped status message the dialog lost when its
PluginScriptRunner refactor was superseded by ActionRegistry.
The merge kept this branch's PluginConfig design, which deletes
PluginDescriptor::settings, get_plugin_settings() and ctx.params, but left
references to them behind: the slic3rutils target did not build, and the
bindings test still asserted the removed ctx.params attribute.
Port the two settings tests onto PluginConfig instead of dropping them. They
guard a field bug where a cloud-metadata refresh wiped a plugin's settings and
it silently ran on its own defaults, so the equivalent properties are still
worth pinning: that a stored config survives the refresh, and that an edited
config reaches the plugin through a real dispatch.
Also defer PluginsConfigDialog's web commands off the webview script-message
callback, as PluginsDialog already does. Its remove_preset_override handler put
a modal wxMessageBox on that stack, which is the GTK crash class fixed in
b779a7bfed/f2ccbfc8b5 for the sibling dialog.
Physical dist/speed ignores acceleration/deceleration, giving
underestimated total time (29 min vs real 48 min). M73 from the
trapezoid planner accounts for accel/decel and is closer to reality.
Now we keep physical DISTRIBUTION (proportions per-filament) but
scale the X-axis so total time matches M73 trapezoid estimate.
Replace M73-based timeline interpolation with physical time calculation
from G1 feedrates and M400 delays. M73 has 1-minute resolution and
non-uniform granularity which distorts the time axis (e.g. P83→P100
jump makes last filament appear much longer than it actually is).
Physical timeline computes cumulative time per gcode line from actual
move distances and feedrates, giving accurate filament duration on plot.
Falls back to M73 interpolation when raw gcode lines are not available.
Cloud catalog records never carry [tool.orcaslicer.plugin.settings], so the
metadata merge wiped the locally-parsed settings and plugins silently ran on
their built-in defaults (ctx.params arrived empty).
The M620→M621 firmware toolchange block weight (500x) was only applied
to sparse track sample lines. Hundreds of G1 moves between samples
inside the M620 block got weight=1, causing firmware toolchange to
appear compressed on the timeline plot.
Build continuous M620→M621 line ranges from track samples and apply
weight=500 to ALL lines within those ranges. This makes toolchange
and wipe tower zones proportionally accurate on the timeline.
Add two standalone Python tools for deep comparison and analysis of .3mf
slicing project files:
- compare_slices.py: comprehensive slice comparison with filament usage,
nozzle mapping, tool change sequences, prime tower analysis, temperature
timeline, and automatic critical discrepancy detection
- show_temp_plot.py: interactive HTML temperature timeline plotter for
visualizing heater profiles during multi-nozzle prints
Both tools use only Python stdlib (no external dependencies).
Primary use case: regression testing H2C carousel purge volumes and
BBS compatibility verification.
The upstream _make_wipe_tower() tracked purge volumes per-extruder (2 slots),
which collapsed all H2C carousel filaments into one slot and caused massive
redundant AMS flushing (~40g instead of ~0.4g).
Changes:
- Print.cpp: Replace per-extruder nozzle_cur_filament_ids with BBS
NozzleStatusRecorder that tracks per group_id (carousel slot 0..6).
Use get_nozzle_for_filament() to resolve physical slot per layer.
Select filament_prime_volume_nc for nozzle changes, filament_prime_volume
for filament changes (BBS pattern).
- PrintConfig.hpp/cpp: Register filament_prime_volume (per-filament EC prime
volume, default 45mm³) matching BBS PrintConfig.
- Preset.cpp: Add filament_prime_volume to preset keys list.
Safe for non-carousel printers: group_id == extruder_id when each extruder
has one nozzle, so NozzleStatusRecorder behaves identically to the original
per-extruder tracking.

Drop the orphaned PluginCallbackList (dead
after the PluginManager migration) and hop
run_on_*_callbacks onto the UI thread via
CallAfter, snapshotting under the mutex on the
worker first. Keeps wx subscribers off the
detached load/unload workers.
Only one action source ever existed, so the
IActionSource interface and ScriptActionSource
are gone. ActionRegistry now subscribes to the
plugin loader and enumerates actions directly
in init() - no polymorphism for one impl.
Replace the opaque FNV-hash SpeedDialActionId
with a readable composed id of the form
prefix:title:source_key. Split AppAction's
single source field into source_key (stable
identity, e.g. plugin_key) and source_name
(display), so identity and display no longer
share one field.
