Fix Windows crash in Replace all with 3D file
Keep the replacement result message as wxString and substitute the volume
name directly.
On Windows, wxString::ToStdString() cannot encode the Unicode status icon
through the active ANSI code page and returns an empty string. Passing that
empty string to boost::format with a volume-name argument throws
boost::too_many_args and exits OrcaSlicer.
Replace per-printer auto-activation
(is_current_printer_agent_plugin)
with a global experimental AppConfig
toggle, default off: legacy
print-host behavior is unchanged
until the user opts in. The toggle
drives device-tab routing, print
button defaults, connect-button
visibility and sidebar layout, and
dedups machine-select dialog opens.
* For dialog without explicitly `SetMinSize`, we should use `SetSizerAndFit` instead, otherwise the dialog will not show correctly on GTK3. (OrcaSlicer/OrcaSlicer#14561)
- and if `SetSizer` is called before the full layout has been built, then an extra `SetSizeHints` should be called before layout/fit so the min size can be properly set automatically based on children's min sizes accordingly.
* Fix GTK3 dialog min size: SetSizer → SetSizerAndFit for dialogs without explicit SetMinSize
Replace SetSizer() with SetSizerAndFit() in 11 dialog constructors that
neither call SetMinSize() nor SetSizeHints(), ensuring proper minimum
size propagation from child widgets on GTK3.
SetSizerAndFit internally calls sizer->SetSizeHints(window), which
sets the window's minimum size based on children — the same fix
applied to ProjectDropDialog in 8a7662083e.
Also drop sizer->Fit(this) calls where present, since they only
resize but don't set the min size hint needed by GTK3.

## 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.
Give previously-bare panels a keyed background so the existing dark-UI walk
can theme them. Runtime-created widgets (HMS items, device firmware/nozzle
panels) route their whole subtree through one UpdateDarkUIWin(this) call
instead of per-widget darkModeColorFor, which also themes their child text
and follows live light/dark switches. Extruder-card chips re-apply their
colours from Sidebar::sys_color_changed so a live switch updates them too.
Replace hand-rolled nozzle type comparison + Hybrid hack with
BBS-style NozzleGroupInfo comparison in check_ams_status_impl.
Previous approach: direct nozzle_volume_type == printer_flow_type
with a Hybrid tolerance lambda. This either suppressed the dialog
entirely (Hybrid always matched) or showed it on every Preview switch.
New approach (matching BBS):
- Build preset NozzleGroupInfo from extruder_nozzle_stats config
- For Hybrid presets: expand into per-type counts (Std#N, HF#M)
- nozzle_count==0 (never synced): dialog appears for first sync
- nozzle_count>0 (after sync): compare with printer GetNozzleGroups()
- Counts match → dialog suppressed on Prepare↔Preview switches
Safe for all multi-extruder printers (H2C, H2D): non-Hybrid presets
use single NozzleGroupInfo per extruder. Single-extruder printers
exit at is_multi_extruders() guard before reaching this code.

reslice() now enforces only the missing-plugin block via
refresh_missing_plugin_block (no second Print::validate); plate
ready-status returns to upstream's plain model_fits, matching
GLCanvas3D::reload_scene. Also restores main's use_bbl_device_tab and
the check_track_enable comment, and drops two unused MainFrame includes.
Resolve five conflicts, all of which needed both sides rather than a pick:
- BackgroundSlicingProcess: ours was a pure tabs->spaces reformat of base, so
keep main's per-filament volume/nozzle map read-back (its only change here).
- GUI_App: main's #12506 else-if attached to an `if` this branch deleted;
re-expressed onto the same-agent early-return path (the agent factory caches
per id, so pointer equality is the same predicate).
- MainFrame: both sides relocated Sync Presets independently; keep main's
push_notification plus the branch's Plugins menu items.
- Tab: the "TODO: Orca: Support hybrid" blocks were unchanged base, not a branch
decision; take main's enabled Hybrid to match the already auto-merged siblings.
- test_config: union of both sides' cases (6 plugin + 9 multi-nozzle).
* Fix issue that switching printer profile is slow.
`wxGetApp().get_tab(preset_type)->select_preset(preset_name);` is called twice when switching printer profiles. Only one needed.
* Avoid unnecessary type conversion & function call during printer profile switching:
- Don't call `config->opt_string("printer_model")` repeatedly
- Use ref when possible during iterating
- Avoid unnecessary `wxString` to `std::string` conversion
HoverLabel's constructor used SetSizerAndFit, which records the
count-hidden width as the panel's explicit minimum size. An explicit
minimum outranks best size in sizer allocation, so once the "(N)" count
was shown, any ancestor Layout() - e.g. switching the extruder flow type
to Standard or High Flow - shrank the title row back to the stale width
and clipped the trailing edit button. Hybrid only appeared correct while
nothing had re-laid the row since its own Fit().
Use plain SetSizer and, on every title/count change, invalidate the
cached best size and re-lay both the row and its parent so the sizer
always allocates the current content width.
- FilamentMapDialog's manual page understands volume types: a mixed
(Hybrid) extruder shows separate Standard / High Flow drop zones
with live sub-nozzle counts, a validation timer with an inline
error + "set nozzle count" suggestion, and composes a per-filament
volume map on OK (persisted to the plate or globally)
- switching an extruder's Flow type rewrites the affected plate map
entries; plate maps stay sized across filament add/delete/count
changes (values keep their filament, no index shift)
- CLI: manual mapping on multi-nozzle printers synthesizes the volume
map from extruder flow types when absent; nozzle-manual mode
requires explicit maps; computed maps land on the plate so exported
projects carry filament_volume_maps
- filament_nozzle_map joins the project options (selection seeding +
filament-count resizing)
- pot entries for the new dialog strings
All 19 reference fixtures byte-identical; slicing an exported Hybrid
project reproduces its g-code byte-for-byte with the volume map
round-tripped through model_settings.config.
- Print::update_filament_maps_to_config takes filament/volume/nozzle
maps, backfills an empty volume map from extruder types, rebuilds
filament_map_2, re-expands the per-filament variant arrays, and
recomputes retract overrides keyed by resolved slots
- grouping writes its result back in every non-sequential mode;
manual multi-nozzle grouping validates the user mapping and raises a
translatable error on deviation; the engine's concrete volume
assignment is deliberately not merged yet (per-filament arrays are
already consumed by filament id, so materializing High Flow now
would change motion before the layer-aware resolvers land)
- Print::apply treats the three map keys as engine outputs in auto
modes (erased from the diff and adopted), compares them against used
filaments in manual mode, and keeps the pre-expansion snapshot in
sync with the late normalization pass so rebuilt headers reflect the
sliced state instead of resurrecting stale values
- volume/nozzle maps and extruder_nozzle_stats join the invalidation
group of filament_map (wipe tower + skirt/brim)
- PresetBundle composes full configs with an optional per-filament
volume map (plate map, else defaults derived from each extruder's
flow type); project config keeps the map sized across filament
count changes
- PartPlate stores per-plate volume/nozzle maps; Plater injects them
at every slice-composition site (incl. g-code reload and wipe-tower
estimation); BackgroundSlicingProcess reads engine results back to
the plate in auto modes
- per-filament map trust guards relaxed to size-match everywhere now
that every producer sizes the map; single-filament explicit flow
assignments are honored
- tests: grouping volume maps stay concrete, merge semantics of
update_used_filament_values, single-filament override honoring
Motion g-code is byte-identical fleet-wide including Hybrid projects
(19-fixture gate + repro determinism double-slice). Header deltas:
the map keys now dump real values, and stale pre-normalization values
(e.g. enable_prime_tower on single-used-filament prints) no longer
leak into the config block.
The sidebar extruder cards get an interactive title row — "<name> ( <count> )"
with an edit button — showing the extruder's physical nozzle count on
multi-nozzle printers (hidden elsewhere). Clicking it opens the existing
"Set nozzle count" dialog, which now also handles a Hybrid extruder by
offering both Standard and High Flow counts (an empty mix is rejected) and
shows a hotend thumbnail.
Because `extruder_nozzle_stats` is session-only (saved presets never carry
it, so preset switches rebuild the edited config without it), the stats are
re-baselined whenever they are missing: each extruder starts with
extruder_max_nozzle_count nozzles of its selected volume type. Switching an
extruder's flow type carries its total count over to the new type, except
when the stats came from a device sync — the machine-reported per-type
breakdown must survive a manual flow switch.
The badge refreshes on preset load, flow-type change, manual edit, device
sync, and project load. Single-extruder cards keep the title row but never
enable editing.
An extruder with more than one physical sub-nozzle can hold a mix of
Standard and High Flow nozzles. The Flow dropdown now offers Hybrid for
such extruders (extruder_max_nozzle_count > 1, nil-guarded); grouping
already expands a Hybrid extruder into per-volume nozzle groups from
extruder_nozzle_stats.
- sidebar Flow combo offers Hybrid only for multi-sub-nozzle extruders
- preset lookup treats Hybrid as Standard (presets define no Hybrid
variant); variant strings are never fabricated for it
- printer tab splits a Hybrid extruder into Standard + High Flow rows,
with matching selection-index arithmetic and sync-enable rules
- syncing from a printer whose extruder holds mixed nozzle flows now
selects Hybrid instead of collapsing to the dominant flow type
- send-to-printer flow check: a nozzle-rack extruder validates its
nozzle inventory (mounted + rack) against every needed flow instead
of comparing only the mounted nozzle; mounted-flow lookup is now
per-extruder, fixing an index shift when a nozzle reports no flow
- Hybrid is session-only in app config (stored as Standard), so a
fresh session starts from concrete flow types
Printers whose extruders have a single sub-nozzle (including all
dual-extruder machines without a rack) see no new option and identical
check behavior.
The engine already implements prime_volume_mode (Default/Saving/Fast)
but nothing in the UI could set it, leaving prime-saving unreachable on
multi-sub-nozzle extruders and fast purge unreachable on printers that
support it.
- new PurgeModeDialog with selectable Standard/Fast or
Standard/Prime Saving cards depending on printer capability
- "Purge mode" sidebar button next to Flushing volumes; opens the
dialog and stores the choice in the project config
- printer preset-load gating: button shown only when the printer has
multiple sub-nozzles per extruder or sets support_fast_purge_mode;
stale project values the printer cannot honor reset to Default
- enable fast purge on A2L 0.4 (support_fast_purge_mode), explicit
default 0 in the common machine base
- new dialog strings added to OrcaSlicer.pot
Printers without these capabilities never show the button and their
projects keep prime_volume_mode at Default, so slicing output is
unchanged.
The Filament Track Switch (H2-series accessory, product code O2L-FTS) feeds
every AMS to both extruders through a two-track switch. Port full support
across the device layer, project config, and GUI.
Device / config:
- Model the switch-aware AMS binding (the set of extruders an AMS can feed
and which input track A/B feeds it), switch readiness, the O2L-FTS firmware
module, and the fun2 capability bit for checking a slice against installed
hardware.
- Register has_filament_switcher and enable_filament_dynamic_map as project
config that persists with the project and restores from a saved 3mf, and
force both back to false on every project/printer/CLI load path. Live
device sync is the only thing that sets them true.
GUI:
- Sidebar sync activates the switch from live device state, attributes each
AMS to the extruder its input track feeds, shows a floating status icon
(ready / not-calibrated), and surfaces a one-time tip / not-calibrated
warning.
- Send dialog gains a non-blocking slice-vs-hardware mismatch warning and a
blocking error when a slice needs dynamic nozzle mapping but the switch is
missing or not set up.
- AMS load/unload guards, AMS-view routing glyph + un-calibrated banner +
hidden external-spool road, and mapping-popup external-spool lockout.
- Filament pickers collapse the per-extruder split into a single deduplicated
"AMS filaments" group with a smart-assign toggle when the switch is ready.
- Firmware-upgrade panel lists the O2L-FTS accessory and its version.
- Device-provided filament-change steps (ams.cfs) drive the change-step
display when firmware sends them, including the three switch steps.
- "Load current filament" asks which extruder to feed via a
FeedDirectionDialog when the switch is calibrated.
Inert without the accessory: every path is gated on the switch being
installed (MQTT aux bit 29, default off) or ready, both project flags default
false, and the per-extruder AMS attribution is byte-identical, so AMS state,
the send/load UI, and sliced g-code are unchanged for every printer that does
not report a Filament Track Switch.
Multi-nozzle sync widget, AMS rack-nozzle mapping popup, calibration rework, send-dialog nozzle mapping and extruder-count UI. Includes the fix to persist the AMS sync badge on filament cards (H2C/A2L and direct-sync printers).
* fix: isolate calibration temp paths per user
The calibration temp files under <temp>/calib were file-scope statics
initialized before set_temporary_dir() runs at startup, so they kept
using the shared system temp root and missed the per-user isolation
added in #14607. On Linux every account shares /tmp, so the first user
to calibrate owns /tmp/calib and later users fail to write there, the
same cross-user collision #14607 fixed for model backups, STEP import,
and part skip.
Build the paths lazily from temporary_dir() instead, through a
calib_temp_dir() accessor and a calib_temp_file() join helper. The base
becomes <temp>/orcaslicer_<uid>/calib on Linux and is unchanged on
Windows, where the temp dir is already per user.
Also make StoreParams::path a std::string rather than a non-owning
const char*. The calibration code had to keep a std::string alive
solely to feed that pointer, and the field was uninitialized by
default; owning the string removes the lifetime hazard for all three
callers and makes the entry guard a reliable empty() check. Confined to
the 3mf project exporter (three callers, two internal reads); no
on-disk, format, or ABI impact.
Follows up on #14607 per @Noisyfox's review suggestion.
* Fix reload from disk for STEP models after reopening a project (#12992)
reload_from_disk matched reloaded source volumes with an exact
source.input_file string comparison. After a project is saved and
reopened, the stored source path is only the filename (the default,
non-full-path save) while a freshly re-imported volume carries a full
path, so the comparison never matched: reload fell into fail_list and
the "locate file" dialog was effectively useless for STEP models.
Fall back to a case-insensitive filename comparison when the exact
paths differ, so the existing same-folder source lookup (and the
locate dialog) can reload the model. Projects that stored absolute
source paths still match exactly as before; no 3mf format change.
* Add Preferences option to store full source paths in projects
Expose the existing export_sources_full_pathnames setting (previously
only editable in the config file) as a checkbox under Preferences >
General > Project. Enabling it stores absolute source paths in saved
projects, so "Reload from disk" works when the source file is kept in
a different folder than the project (companion to #12992).
