What's Changed

This is the OrcaSlicer V2.4.1 release — a maintenance update on top of 2.4.0 with a broad round of profile and preset fixes at its core: it restores filaments that had gone missing or were miscategorized in the Orca Filament Library and the filament selection dialog, de-duplicates profile setting IDs, corrects ambiguous AMS filament matches, and improves how renamed and inherited presets are resolved. Other changes include a native Windows ARM64 build, a new minimal chamber temperature field, and a reworked skirt and brim generator (fixing a 2.4.0 regression that re-printed the skirt during per-object/sequential printing), alongside fixes for fuzzy skin, AMS sync ordering, CrealityPrint hosts, and Linux Wayland rendering. It also adds Snapmaker U1 nozzle profiles, Elegoo Centauri 2 support, and a refreshed translation catalog.

🌊 New Features & Improvements

• Native Windows ARM64 build (Snapdragon X Elite) by @abehrman in 14059, brought up to date and merged by @SoftFever in 14381
  Adds a green, native Windows-on-ARM build (not x64 under emulation) for Snapdragon X Elite and other Windows ARM64 devices, folded into the standard Windows build matrix. It ships full feature parity — STEP/STP import, SVG→3D, and text emboss all build and work on ARM64 — with the x64/x86 build paths unchanged. This is a build/CI addition; wiring ARM64 into the official signed-release pipeline (code signing, installer) is a follow-up. The original work and authorship are @abehrman's (#14059); #14381 simply brings that branch up to date with main. With the new ARM64 builds, the Windows x64 installer and portable downloads now carry an _x64 suffix in their filenames to distinguish them from the ARM64 ones.

• Minimal chamber temperature field by @igiannakas in 14340
  Adds a per-filament "Minimal" chamber temperature alongside the existing value (now labelled "Target") in the filament settings, exposed to print-start macros as the chamber_minimal_temperature variable. This lets a start macro begin printing once the chamber reaches a threshold — for example, start at 50 °C while the chamber keeps heating toward a 60 °C target. The value is validated against the target (it warns and clamps if set higher) and is not emitted via M141/M191; it defaults to zero for existing profiles.

  

• Skirt and brim generation rework by @kisslorand in 14333
  Reworks skirt and brim generation into a single, shared flow and fixes a regression introduced by the 2.4.0 skirt overhaul affecting per-object and sequential (By Object) printing: with a skirt enabled, the skirt could be re-printed before each object — running the nozzle back over it, or even knocking already-printed parts off the plate — and the object print order was not respected. Skirts are now tracked per group and per print height so each one prints exactly once. In By Layer mode with per-object skirts, the order is now skirt → brim → object for each object (previously all skirts printed first), and brims print together with the object or group they belong to while Combine brims still merges touching brims. Draft shields are generated through the same logic, fixing cases where a draft shield failed to generate at Skirt height = 0 or overlapped the brim. Unsafe By Object configurations that would need a shared multi-layer skirt or draft shield are now rejected with a clear slicing error. Fixes #14319 and #14366.

• Warning dialog about the profile-sync change by @SoftFever in 14377
  Adds a one-time warning dialog explaining the profile-sync behavior change introduced in 2.4.0, so users understand how their profiles are synced before it affects them.

  

• Specify the plate index for 3MF uploads by @SoftFever in 14404
  When sending a job as a packaged .gcode.3mf, the upload now names which plate to print. Because the G-code inside a .gcode.3mf is index-coded and a bundle can carry several plates, the OctoPrint and Moonraker hosts now forward a plateindex field so the correct plate prints; servers that don't use it simply ignore the field, leaving the plain G-code path unchanged.

🛠️ Bug Fixes

Profiles & presets

• Fix filament inheritance issues in Custom Printer Creation by @yw4z and @SoftFever in 12060
  Creating a printer for several vendors (Chuanying, Lulzbot, MagicMaker, Snapmaker, Sovol, TwoTrees, Z-Bolt, and some Bambu Lab presets) could fail because filaments that inherit from the Orca Filament Library weren't found while loading those vendors' profiles. The library is now searched correctly, so these profiles load and the printers can be created; filaments can also be imported from the Orca Filament Library to cut down on duplicates. Fixes #11704.

  Before	After

• Restore filaments missing from the Filament Selection dialog by @ExPikaPaka in 14398
  System filament presets could silently disappear from the setup guide's filament picker: a cache bug corrupted filament-type resolution, so some filaments were filed under the wrong material category (for example, Generic PLA resolved as ABS) and vanished from the expected type filter. Type resolution is now correct, so the affected filaments appear under the right category again. Related to #7292, #14365, and #14248.

  Before (missing)	After

• De-duplicate profile setting IDs by @SoftFever in 14432
  Every profile needs a setting ID that is unique across all profiles — it's what a user preset's parent reference points at — but many vendors had copied Bambu's generic IDs (one ID was shared by over 1,500 files). Each profile's ID is now derived deterministically from its vendor, type, and name, so IDs are unique and stable across runs, with a CI check guarding against collisions. The stricter check also surfaced and cleaned up several long-standing duplicate profiles (Prusa, WEMAKE3D, the Orca Filament Library, and Bambu Lab/AliZ). Bambu's existing IDs are kept as-is for compatibility with Bambu-synced presets.

• Fix ambiguous AMS filament matches on Bambu Lab profiles by @SoftFever in 14459
  A filament is matched from the AMS by its material ID together with printer compatibility, so two presets that share a material ID and are both compatible with the same printer make the match ambiguous — the slicer could silently pick the wrong one. This fixes the 11 Bambu Lab profiles where that happened (over-claimed nozzle compatibility, a copy-pasted printer name, and a wrong inheritance) and adds a profile-validator check to catch any regressions.

• More robust preset resolution on load by @peachismomo in 14429 and 14430
  Improves how presets are resolved when loading: presets whose vendor/system name has since changed are now resolved through their renamed_from mapping, and a preset's stored parent reference is corrected when it's empty or no longer matches the current profile. Together these reduce cases where a renamed or updated system preset fails to link to its parent.

• Fix syncing a shared preset bundle that contains a parentless preset by @ExPikaPaka in 14287
  Downloading or updating a shared (subscribed) preset bundle could fail when the bundle included a preset with no parent, because the parent-availability check assumed every preset inherited from another preset. Presets without a parent are now handled correctly, so shared bundles download and update without error.

• Remove duplicate Flashforge filaments from the system list by @indyjonesnl in 14316
  Several Flashforge filaments (such as "Flashforge PLA Silk" and "ASA Basic" — 15 in total) appeared twice in the system filament list due to overlapping compatible_printers entries in the profiles. The affected presets are repointed to the correct printers and the redundant entries removed, so each filament now shows once with no loss of coverage. The Flashforge profile version was also bumped so the corrected profiles re-sync to existing installs. Closes #10998.

Slicing & printing

• Fix fuzzy skin artifacting regression by @SoftFever in 14382
  Fixes a regression (introduced by #14031) where fuzzy skin could cause wall collapse/artifacting on some profiles. A regression test built from the reporter's profile (0.20 mm Standard @bbl X1C, 0.4 mm nozzle, 2 walls) was added to guard against it. Fixes #14376.

• Fix crash with per-object skirt on an empty plate by @SoftFever in 14403
  Fixes a crash that occurred when By Object skirt was enabled and a model was then added to a focused plate (e.g. add a second plate, switch back to the first, set skirt loops and switch skirt type to By Object, then add a model).

• Fix AMS overwrite sync showing filaments in the wrong order by @SoftFever in 14408
  When syncing the filament list from the AMS with the Overwriting option, the preview listed the AMS filaments in reversed order even though the mapping actually applied was correct. The preview now iterates filaments in a stable, material-index order, so it matches what gets applied. Fixes #14335.

• Wait for nozzle temperature before the purge line by @indyjonesnl in 14120
  Several Artillery (Sidewinder X3/X4 Plus/Pro) and Flashforge (AD5X, Adventurer 5M / 5M Pro) profiles set the first-layer nozzle temperature without waiting, so the purge line could run before the nozzle was hot enough. These profiles now wait for the target temperature (M109) before purging, producing a clean prime line.

Connectivity & hosts

• CrealityPrint: avoid a false "End of file" error on K1-family printers by @sandman21vs in 14344
  Sending a print to a Creality K1-family printer over the crealityprint host popped up End of file [asio.misc:2] even though the print actually started, because the firmware closes the control WebSocket as soon as it accepts the command. The post-send read and close are now best-effort, so a benign disconnect after a successful send no longer reports as a failure.

• CrealityPrint: don't hardcode port :4408 for the Device tab by @totrytakeoff in 14326
  The Device tab WebView no longer forces port :4408 for CrealityPrint printers, which broke setups that route the web UI through a reverse proxy or a different port. It now uses the generic fallback (your configured print_host_webui, otherwise the plain print_host with no port appended). Related to #7747 and #10740.

• Keep pinned networking plugins across app updates by @SoftFever in 19db9aa
  OrcaSlicer lets you pin a specific networking plugin version, but updating the app would remove the existing plugin. Pinned plugins are now preserved across app version updates.

Platform & UI

• Fix the Flow Rate Calibration wiki link by @MarkusKgit in 14378
  The "Wiki Guide" link in the Flow Rate Calibration dialog pointed to a URL that redirected to the wiki home page; it now opens the correct Flow Ratio calibration guide.

• Linux: fix blank/garbled web views on Wayland by @SoftFever in f9693c4
  WebKit2GTK accelerated compositing is unreliable on Wayland, producing blank or garbled web views (such as the Home and Device tabs) with both NVIDIA and AMD drivers. Compositing is now disabled whenever a Wayland session is detected (covering native Wayland and XWayland), and the Flatpak build uses fallback-x11; pure X11 sessions keep hardware acceleration.

• Linux: allow AppImage execution for non-owner users by @pallaswept in 14339
  The 2.4.0 AppImage set execute permissions only for the owner and group, which prevented it from running as another user — for example inside a firejail sandbox or when the AppImage is extracted (as the AUR package does). Execute permission is now granted for others as well.

🖨️ Printer & Filament Profiles

• Snapmaker U1 — adds 0.2 mm and 0.8 mm nozzle profiles and completes the 0.6 mm process lineup, and fixes the bed dimensions (270 × 270 mm) so all nozzle variants show the correct build area by @ni4223 in 14305 and 14391

  

• Elegoo Centauri 2 — adds machine, filament, and process profiles, synced from ElegooSlicer by @wujie-elegoo in 14402

  

• QIDI X-Max 4 — now uses the qidi printer agent by default, so it connects without having to set it manually by @thelegendtubaguy in 14334

🗪 Localization

• Translation catalog refresh across the bundled languages — Catalan, Czech, German, Spanish, French, Hungarian, Italian, Japanese, Korean, Lithuanian, Dutch, Polish, Brazilian Portuguese, Russian, Swedish, Thai, Turkish, Ukrainian, Vietnamese, and Chinese (Simplified & Traditional) by @SoftFever in e3eca45
