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.
* Build 2 Checkpoint
* fix support generation wedge, ghost layers
* flip cornering tests 180 deg to waste less supports
* fix row spacing on the flow ratio calibrations
* more testing, this didn't fix anything
* switched rotation tools, same issue
* fixed Z-offset issues
* add rest of PA features, may look a bit weird on a belt
* make temp towers work
* re-enable spiral on calibrations that want it
* Final cleanup pre-PR and community testing
The IdeaFormer IR3 V2 End G-code ran `G28 ; home all`, which homes the
Z (belt) and Y (gantry) axes. On a belt printer Z is the conveyor, so
homing it runs the belt all the way back to origin, dragging the finished
part back under the gantry that G28 has just lowered — the head knocks the
print (reported by an IR3 V2 user; the `G1 Y50` lift came after the G28,
too late).
Replace the end sequence with a belt-safe one: switch to relative mode
(G91), lift the gantry for clearance, advance the belt forward one full
machine-depth (Z676, the 676 mm product depth) to eject the part and cycle
the belt surface clean, then home X only — never the Z/belt axis.
collect_layers_to_print() warns (CRITICAL) when an extrusion layer sits above
the previous one with an empty gap below — the fixed-bed assumption that
material with nothing under it is floating and unprintable. On a belt printer a
*leading* empty range (the gap starts at Z=0, no prior extrusion layer) is not
floating: it is the conveyor lead-in, and the part rests on the advancing belt
as the first material is laid down well above Z=0. A part not designed for a
belt (e.g. a flat test model tilted into the belt frame) then trips this as a
false "Object can't be printed for empty layer between 0 and N" error.
Suppress only the leading case (belt_printer && last_extrusion_layer == null);
genuine internal gaps are still flagged, since on a belt those can be an
over-angle overhang printing into air. Non-belt output is unchanged.
* fix: tombstone resolution for 409 status code with error code -3
* fix: add resolution for undefined conflicts
* fix: generate setting id if it is empty for 409 tombstone
* fix: force push empty setting_id preset on 409 tombstone
* clearner solution
* Sync Elegoo profiles from ElegooSlicer
Update vendor Elegoo.json, filament/machine/process trees, and OrcaFilamentLibrary
Elegoo entries. Align machine default material names with existing filament preset names.
* feat: expose filament_name for G-code export filename format
Derive from filament_settings_id for the first active extruder and strip the suffix after @, matching ElegooSlicer so filename_format can use {filament_name}.
* chore: reorder Elegoo entries in OrcaFilamentLibrary
Group Elegoo @base profiles and bump library version to 02.03.02.62.
* sync OrcaFilamentLibrary.json with Elegoo filament profiles
* fix: clean up Elegoo process renamed_from for profile validation
Add single renamed_from only where preset names changed from legacy Orca
names; remove duplicate Rapid @System library entries that conflicted with
ECC2 vendor presets.
* fix(profiles): add missing Elegoo renamed_from for profile validation
CI custom-preset tests still inherit legacy Orca preset names that no
longer exist after the Elegoo bundle update. Add renamed_from on process,
Neptune 4 machines, OrcaFilamentLibrary filaments, and Giga profiles so
inherits resolve again, without changing print parameters.
* fix(profiles,elegoo): resolve renamed presets and CC2 SET_PRINT_STATS_INFO G-code
Resolve legacy preset names through renamed_from when validating presets and loading external projects. Add missing renamed_from aliases for Elegoo Giga process and OrcaFilamentLibrary filaments. Combine TOTAL_LAYER and CURRENT_LAYER in one SET_PRINT_STATS_INFO command on Centauri Carbon 2 (ECC2), Centauri (EC), and Centauri Carbon (ECC) 0.4 nozzle profiles.
* chore(profiles): bump Elegoo and OrcaFilamentLibrary profile versions
Refresh installed profile bundles after renamed_from aliases, CC2 SET_PRINT_STATS_INFO G-code, and Preset.cpp renamed preset resolution fixes.
* Add IdeaFormer IR3 V2 belt printer profile
Self-contained vendor profile for the IdeaFormer IR3 V2 (45 deg belt printer):
machine (0.4 nozzle) + 0.20mm process + Generic PLA/PETG filaments, with the
belt machine-frame transforms set explicitly on the machine preset
(belt_printer, belt_slice_rotation x/45/global, build_plate_tilt_x=45,
gcode_remap_x/y/z, gcode_shear_z=pos_tan, gcode_scale_y=inv_cos).
The vendor bundles its own machine/process commons (fdm_belt_common,
fdm_klipper_common, fdm_machine_common, fdm_process_common) on purpose:
OrcaSlicer resolves system-preset inheritance per-vendor, so a profile that
inherits the Custom vendor's commons cross-vendor fails to resolve its parent
and the whole IdeaFormer vendor silently fails to load. Bundling the commons
(and listing them in IdeaFormer.json in dependency order) keeps the vendor
self-contained, matching how every other vendor folder is structured.
Machine limits, bed temperature (75 C for belt PLA) and start/end G-code are
taken from a working IdeaFormer IR3 V2.
* feat(belt/profile): eSUN PLA @IdeaFormer IR3 V2 — HW-calibrated belt filament
Add an eSUN PLA belt profile for the IR3 V2, inheriting Generic PLA @IdeaFormer
IR3 V2 (self-contained: parent is in the same IdeaFormer vendor, registered
after it in filament_list). HW-calibrated on the IR3 V2:
- nozzle_temperature 200/200 (temp-tower calibration)
- pressure_advance 0.12 (PA calibration)
- filament_max_volumetric_speed 10 mm³/s (max-vol-speed calibration: wall
failed at 126 mm/s → 126 × 0.0798 mm³/mm ≈ 10 mm³/s)
* Fix junction deviation and jerk settings behavior
Process settings now follow the selected printer's junction deviation
configuration. When machine_max_junction_deviation is enabled,
default_junction_deviation is shown and jerk settings are hidden. When
junction deviation is disabled, jerk settings are restored and
default_junction_deviation is hidden.
Fix a validation issue where junction deviation mismatch warnings could
be reported even when machine_max_junction_deviation was set to 0.
Warnings now apply only when junction deviation is active and point
directly to default_junction_deviation.
Also simplify Motion ability page visibility checks by reusing local
firmware-flavor booleans.
* GUI tweak
- separate Junction Deviation segment
- JD and Jerk stay visible
Switching to a printer with fewer filaments (e.g. H2D -> X2D) threw
std::out_of_range in check_filament_printable. Clear stale per-volume
extruder config on count shrink and bound-check filament indices at the
read sites.

Support fixes for .7 and 1.0 nozzles

## 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)
