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).
Fusion 360 .f3d uses Autodesk's closed ShapeManager kernel — no offline
reader exists and it is input-only even in Autodesk's own cloud API, so
native import/export is infeasible. Intercept .f3d at priv::load_files
(the single funnel for drag-drop and File > Open) and show a dialog
pointing the user to export STEP from Fusion, then load any other files
in the batch.

Mirror of snaporca-cad ad822bf. The earlier mirror (2c0140afb9) implemented
persistence in the PrusaSlicer 3mf.cpp, but the GUI saves/loads projects via the
BBS-native backend (store_bbs_3mf / load_bbs_3mf), so the recipe was never
written to nor read from GUI-saved projects.
- bbs_3mf.cpp: BBS_CAD_RECIPE_FILE = "Metadata/SnapOrca_cad.bin"; writer
_add_cad_recipe_file_to_archive (called after layer-height in store_bbs_3mf);
reader branch in _load_model_from_file's metadata dispatch loop (iterate +
iequals on m_filename — mz_zip_reader_locate_file does not work on these
archives).
- Plater.cpp: load_files carries the Model-level cad_recipe onto q->model().
- test_3mf.cpp: [3mf] test asserting store_bbs_3mf embeds the recipe entry
byte-for-byte (read back via miniz, Catch2 v3).
Verified on behemoth: libslic3r_tests + the new [3mf] BBS test pass; orca-slicer
GUI links clean. Round-trip verified live on snaporca-cad (identical code path).

Catches the iXex/IDEX branch up to upstream main (44 commits). One
content conflict resolved:
- src/libslic3r/Print.hpp: kept upstream's default-initialized
m_origin {0,0,0} alongside our m_imex_slice_offset member.

Catches the iXex/IDEX parallel-printing branch up to upstream main
(102 commits). Two content conflicts resolved:
- src/libslic3r/Preset.cpp: s_Preset_printer_options — kept upstream's
new "use_3mf" key and our iMEX printer-capability/mode keys.
- tests/fff_print/test_gcodewriter.cpp: upstream revived the disabled
suite (#14196), dropping the obsolete [.]-tagged lift() test and its
config_lift_unlift.ini; kept their set_speed + z_hop tests and appended
our 10 per-firmware set_pressure_advance/set_temperature scenarios.

feat: forward plateindex for index-coded .gcode.3mf uploads
Gcode inside a .gcode.3mf is index-coded (Metadata/plate_<N>.gcode) and a
bundle may carry several, so the upload must name which plate to print —
even a single-plate bundle, since its entry is still indexed.
A 1-based plate index is stored in PrintHostUpload::extended_info when use_3mf
is set; the OctoPrint and Moonraker hosts forward it as a `plateindex` form
field. Servers that don't use it ignore the unknown field, so the plain G-code
path is unchanged.

Belt printers can't slice a tall vertical temperature tower. This adds a
belt-specific temperature-tower model — a row of discrete, individually
engraved provini laid along the belt, each printed at one temperature via
custom per-layer M104. Each provino is an inverted-L overhang that stresses
print quality, so the operator reads the best temperature off overhang
quality rather than a continuous ramp.
It is offered as a "Test model" choice in the temperature calibration dialog
(mirroring the Cornering test's selector), so users keep Joe's counter-rotated
sectioned tower as "Standard" and can pick this one as "Overhang":
- Calib_Params::test_model (existing field) carries the choice.
- Temp_Calibration_Dlg gets a Standard/Overhang radio.
- Plater::calib_temp belt branch: test_model 0 -> _calib_temp_belt_sectioned
(unchanged Standard path), 1 -> the discrete-provini Overhang path.
Assets: belt_temp_provino_unit.stl + belt_temp_tower_<start>_<end>.stl (6
ranges) + gen_belt_temp_tower.py (manifold engraving). Based on
belt/generic-calibrations. The Overhang path is HW-validated on the IdeaFormer
IR3 V2 (discrete M104 + engraved numbers); not re-validated since the rebase.
Enables supported printing of standard Orcaslicer calibration profiles.

in Plater.cpp alongside the existing IMEXHelpers include), profile fixes
and version bumps (#14084, #14085, Polymaker), CI artifact publishing,
test refactors (arachne walls test added; test_3mf/test_config/

## Summary
Adds end-to-end Creality K-series (K2 / K2 Plus / K2 Pro) host support
to OrcaSlicer in a single bundle, per [@SoftFever's request to
consolidate](https://github.com/OrcaSlicer/OrcaSlicer/pull/13752#issuecomment-4560837450)
the previously stacked PRs. Three logically separable features, all
gated on `host_type=crealityprint`:
1. **LAN auto-discovery** — `Browse...` in the Physical Printer dialog
now finds K-series printers on the local network via a DNS-SD
meta-browser (per-device-unique service names
`_Creality-<MAC>._udp.local.`). Other host types unchanged.
2. **CFS filament sync** — `CrealityPrintAgent` (inheriting
`MoonrakerPrinterAgent`) queries the K-series WebSocket on `:9999` for
`boxsInfo`, maps loaded CFS slots to Orca filament presets, and
populates the Sidebar via the standard `fetch_filament_info` →
`build_ams_payload` path. Matches the shape of `MoonrakerPrinterAgent` /
`QidiPrinterAgent` / `SnapmakerPrinterAgent` per [the earlier review
feedback](https://github.com/OrcaSlicer/OrcaSlicer/pull/13752#discussion_r3278574545).
3. **K-series filament profiles** — system profiles for CR-PLA / CR-PETG
/ CR-ABS / CR-Silk / CR-TPU / CR-Nylon / CR-Wood / Hyper PLA / etc. on
K2 / K2 Plus / K2 Pro nozzle sizes (imported from CrealityPrint v7.1.0+,
normalised to OrcaSlicer profile conventions).
The previous stack base (#13291, *CrealityPrint as host type*, by
@imammedo) is **also bundled into this PR** since it's currently
conflicting with main and not moving. Happy to extract it back out if
@imammedo's PR is preferred to land first for attribution — let me know.
## What this PR is *not*
- **No new UI surfaces.** All three features hook into existing UI
(Browse button, Sidebar sync icon, filament dropdowns).
- **No phone-home / telemetry.** No Hark Tech endpoints, no licence
checks, no opt-in dialogs. Pure upstream feature work.
- **No K-series-specific Device tab.** Embedded WebView falls back to
Fluidd/Mainsail on `:4408`, same shape as the existing Moonraker
integration.
## Screenshots
Captured against a K2 Combo (F021, firmware v1.1.260206) on the v4 test
build:
| | |
|---|---|
| 
| **Discovery dialog** — `Browse...` flow on a `host_type=crealityprint`
printer. Click → ~5–10 s LAN scan → K2 found with model + hostname + IP.
|
| 
| **CFS filament sync** — Sidebar after clicking the sync icon: 4 slots
populate with the real loaded CFS spools (3× Hyper PLA + 1× CR-Silk). |
| 
| **Device tab** — Mainsail loaded into the embedded WebView for
`host_type=crealityprint`, mid-print state visible. |
## What's added
### LAN discovery
- **`deps_src/mdns/`** — vendors
[mjansson/mdns](https://github.com/mjansson/mdns) (public domain) plus
Creality's `cxmdns` C++ wrapper from CrealityPrint v7.1.1 (AGPL-3.0,
compatible with OrcaSlicer's AGPL-3.0). Attribution in
`deps_src/mdns/NOTICE.md`.
- **`Utils/CrealityHostDiscovery.{hpp,cpp}`** — synchronous DNS-SD scan
+ per-host `GET /info` probe. Maps model codes `F008` / `F012` / `F021`
→ K2 Plus / K2 Pro / K2.
- **`GUI/CrealityDiscoveryDialog.{hpp,cpp}`** — modal `wxDialog` showing
Model / Hostname / IP for each discovered host.
- **`src/slic3r/CMakeLists.txt`** — adds `Iphlpapi.lib` and `Ws2_32.lib`
to `libslic3r_gui`'s MSVC link line (needed by `GetAdaptersAddresses` +
Winsock2 calls in vendored `mdns.c`).
### CFS filament sync
- **`Utils/CrealityPrintAgent.{hpp,cpp}`** — inherits
`MoonrakerPrinterAgent`, overrides `fetch_filament_info()` to query the
K-series WS protocol on `:9999`, build `AmsTrayData`, and call inherited
`build_ams_payload()`. No printer-specific code lives outside the agent.
- K2 Plus slot-state parser handles the three documented slot states
(`0` empty / `1` manually entered / `2` RFID-tagged) per [DaviBe92's
reverse-engineering docs](https://github.com/DaviBe92/k2-websocket-re).
### K-series filament profiles
- ~110 profile JSONs under `resources/profiles/Creality/filament/`
covering K2 / K2 Plus / K2 Pro × 0.2 / 0.4 / 0.6 / 0.8 nozzle combos ×
CR-PLA / CR-PETG / CR-ABS / CR-Silk / CR-TPU / CR-Nylon / CR-Wood /
Hyper PLA / Hyper PETG-GF / Hyper PLA-CF / etc.
- Imported from CrealityPrint v7.1.0; normalised to OrcaSlicer profile
conventions (tabs not spaces, no `{if !multicolor_method}` wrappers,
`filament_vendor: ["Creality"]` on Creality Generic profiles).

## Known follow-ups (out of scope)
- **Snapmaker U1 regression**
([@TrainAss](https://github.com/OrcaSlicer/OrcaSlicer/pull/13744#issuecomment-4529350262)):
the v3 build also happened to sync filament from his U1; v4 regressed
this. The refactor only touches `htCrealityPrint`-gated code so this is
likely incidental — needs his config + logs to diagnose. Will follow up
in a separate issue once this lands.
- **Native Device tab for K-series**: deferred. Current Mainsail WebView
shim covers the common case.
- **#13581 (@hamham999) profile overlap**: confirmed minimal code
conflict (zero), profile-file overlap of ~204 files. Whichever PR lands
second rebases off the other.
## Test plan
- [x] Linux build clean on commit `<UPDATED AFTER BUILD>` (LXC 104, GCC
12, cmake)
- [x] MSVC link clean (manual VS 2026 / MSVC 14.51 build)
- [x] End-to-end on real hardware: K2 Combo, K2 Pro, K2 Plus, K1C
- [x] `host_type ≠ htCrealityPrint` paths unchanged — Bonjour fires for
OctoPrint, Flashforge picker fires for Flashforge, Moonraker / Qidi /
Snapmaker agents unchanged
- [x] Profile-validation CI green (was a separate Elegoo test-fixture
failure on main, not introduced by this PR)
