Conflicts were all co-located additions rather than design collisions:
- GCode.cpp: adopt upstream's toolchange(filament_id, nozzle_id) signature and
per-variant set_config_index() while keeping the IMEX bare-T<n> suppression;
rebase the second-layer temperature loop's non-IMEX branch onto upstream's
get_filament_config_index() resolution.
- Preset.cpp / PresetBundle.cpp / PrintConfig.cpp: keep both sides' option-list
and enum-map entries.
- GLCanvas3D.cpp: upstream's printable_heights argument plus the IMEX ghost pass.
- PartPlate.cpp: keep <set> (still used).
- test_gcodewriter.cpp / test_3mf.cpp: keep both sides' test cases.
Resolves two conflicts:
- GLCanvas3D.hpp: keep both the IMEX ghost render declarations and
upstream's _render_wireframe_overlay().
- test_gcodewriter.cpp: both sides appended test cases to the same
region; keep upstream's origin/machine-limit tests alongside the
pressure-advance and temperature scenarios.
* 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).

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.

## 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)
