Snapmaker-Ultra v2.3.6.4-ultra

Snapmaker-Ultra v2.3.6.4-ultra

First release with Windows installer, Linux AppImage and an unsigned macOS build alongside the Win64 portable zip.

Highlights

Assembly tools (new)

• Auto-Fit Assembly (right-click a multi-selection): mates parts automatically by matching faces, holes and pins, then merges them into one print-ready object.
• Assemble tool → Auto-fit: pick one feature on each part (flat face, circular rim, single triangle, or a curved patch), press Auto-fit, fine-tune with the live Rotate ±180° / Offset ±20 mm sliders, then Merge parts. Rotation is chosen by outline fit and a whole-mesh collision check so pegs seat square without intersecting.
• New assembly modes: Triangle and triangle, Curve and curve; Point and point now snaps to vertices at any zoom and has a one-click Coincide points.

Bambu Lab, including dual-nozzle (in progress)

• H2D / H2C / X2D AMS-aware filament→nozzle grouping from the connected printer's AMS layout, with flush optimisation and 3MF persistence.

Also in this release — see the README for the full list.

Downloads

Platform	File	Notes
Windows 10/11 (x64)	Snapmaker-Ultra_Windows_Installer_V2.3.6.4.exe	Installs side by side with the official Snapmaker Orca (own folder, Start-menu entry and Add/Remove entry); upgrades a previous Ultra install.
Windows 10/11 (x64)	Snapmaker-Ultra_Windows_V2.3.6.4_portable.zip	Unzip and run snapmaker-orca.exe.

The Windows build shows "Ultra version" on the splash screen so you can tell it apart from the official app. Ultra registers its own snapmaker-ultra:// URL scheme and leaves the official snapmaker-orca:// handler alone. (Linux/macOS builds in this release still show the standard splash.)
| Linux (x86_64) | Snapmaker_Orca_Linux_V2.3.6.4.AppImage | chmod +x, then run. Requires libwebkit2gtk-4.1-0 and libopengl0 (Ubuntu names) on the host — they are not bundled. |
| macOS 12+ (universal: Intel + Apple silicon) | Snapmaker_Orca_Mac_universal_V2.3.6.4.dmg | Unsigned — see below. |

macOS: opening an unsigned build

This build is not notarized (no Apple Developer account yet), so macOS will refuse to open it the first time.
Either right-click the app → Open → Open, or remove the quarantine flag once:

xattr -dr com.apple.quarantine "/Applications/Snapmaker Orca.app"

Network / printer connectivity

The Windows packages include the connectivity plugin. The Linux and macOS builds from CI do not include it in this release.

Known limitations

• Curve-and-curve mates align at the patch centre (no full surface registration).
• Adjust sliders are not available in Point-and-point mode (use Coincide points).
• Physically validated on Snapmaker U1; Bambu printers are in progress.

Snapmaker Orca Ultra v2.3.6.3

Snapmaker Orca Ultra v2.3.6.3

Bambu cloud accounts and cloud printers, via the Account menu.

Bambu cloud login

• Sign in to your Bambu Lab account with email/password or Google / third‑party (OAuth) sign‑in.
• Your existing Bambu printers are discovered automatically after login.

Cloud printers

• Connect to cloud printers with live status and chamber light on/off.
• Camera: plays over your LAN for cloud printers that are also on your network (true off‑LAN/WAN camera is not available).

Fixes

• The bundled go2rtc camera helper is now terminated when the app closes (no more leftover background processes), and only ever affects this app instance.

Portable build — unzip and run snapmaker-orca.exe. The bundled network plugin installs itself on first launch.

Snapmaker Orca Ultra v2.3.6.2

Snapmaker Orca Ultra v2.3.6.2

Highlights

• Bambu Lab LAN support — connect Bambu X1 / P1 / A1 printers over your local network: live status, camera, print send with AMS mapping, and controls (pause / resume / stop, chamber light, speed). Powered by a bundled clean-room network plugin — no Bambu account or cloud required. Put the printer in LAN Only Mode (or use a LAN-visible printer) and add it with its IP + access code.
• Nozzle flow type (Standard / High Flow) — now declared to Bambu printers and automatically matched to the installed nozzle, so sliced files no longer trip a nozzle-flow mismatch.

Fixes

• Eliminated a false "nozzle mismatch" warning that appeared on every print send (corrected the nozzle-type check and added parsing for the newer HX-series nozzle codes).
• Fixed a crash caused by the live Bambu camera during a print send — the camera no longer auto-starts on the Device tab; press Play to view it.
• Suppressed the spurious "Using a BambuSource from a different install" video warning.
• Removed the save / transfer / discard preset dialog when switching between Snapmaker U1 devices on the Device tab.

Also included

• Refreshed QIDI printer and filament profiles.

Windows 64-bit portable build. Unzip and run snapmaker-orca.exe. The bundled network plugin installs itself on first launch.

Snapmaker Orca Ultra v2.3.6.1

Snapmaker Orca Ultra v2.3.6.1

Windows portable build. Unzip and run snapmaker-orca.exe.

New in this release

• Outer wall filament — outer walls can print with their own filament, separate from inner walls (Strength > Extruders; "Default" follows the Walls filament). Follows per-object extruder assignments like the other per-feature filaments.
• Spool Manager — connect to a self-hosted Spoolman server: live spool inventory, bind spools to filament slots, and deduct sliced filament weight automatically when a job is sent (or manually per plate). Enable in Preferences > Ultra.
• Offset layers (experimental) — odd inner walls print raised by half a layer height so adjacent wall interfaces interlock vertically, for stronger inter-layer bonding (Strength; not compatible with Inner/Outer/Inner wall order).
• Merge into Single Part — select several parts of one object and merge them into one part, preserving paint/seam/support annotations and part type (port of OrcaSlicer#15413).
• Print unsupported walls last — wall loops floating entirely in mid-air wait for the walls/infill that anchor them (Quality > Overhangs; port of OrcaSlicer#15411).
• Undertop surface pattern — choose the pattern of the solid layer directly under a less-than-100%-density top surface (Strength; port of OrcaSlicer#15389).
• Per-filament Z offset — filament-level Z offset applied on top of the printer's (Filament > Advanced).
• Bottom-referenced Z — Move panel's Z can show the object's bottom height above the bed instead of the center (Preferences > Ultra).
• Drop-to-bed toggle — imported models can keep the Z position stored in the file (Preferences > Ultra).
• Machine prepare time — a printer-level warm-up allowance added to print time estimates.
• Import config from G-code — File > Import reads the settings block out of a sliced G-code file.
• orcaslicer:// links — "Open in Orca" buttons on Printables and similar sites now open models directly.
• Silent exit — closing the app no longer prompts to save or discard modified presets; the project 3mf carries the live settings.
• Part visibility — eye column in the object list cycles Visible > Ghost (X-ray) > Hidden per object or per part, with right-click Visibility on any selection including multi-select.

Carried forward from v2.3.6-ultra

• Stream tab — multi-camera wall (up to 4x4) with aliases: Snapmaker U1 (incl. HD LAN), Moonraker, Bambu P1 (built-in relay), X1/H2 (via go2rtc).
• Ultra Preferences tab — Auto-Save every N seconds, Keep My Printer on project open, Skip Settings Mapping Warnings, Prefer Last Used Print Profile (remembers per layer height), Seamless System Filament Edits.
• Modeling tools — Manifold-based mesh booleans and OpenVDB Repair/Remesh (with automatic fallbacks), mesh-boolean part picker, Assemble Separately and Separate, plate/object align helpers in the Move panel, double-click part selection.
• Filament tools — Apply All for filament dropdowns, per-feature filament selection (walls / sparse / solid infill).
• Z overrides X/Y support option.

Fixes to upstream Snapmaker Orca / OrcaSlicer issues

• Crash when deleting a plate while a slice was in progress.
• Fuzzy skin no longer leaves random dots on outer walls in extrusion/combined mode (width floor used wrong units) or blobs near seams (missing point spacing across the loop closure).
• JSON config files with unquoted numbers or booleans no longer silently lose those settings — including inside per-filament lists (port of OrcaSlicer#15370, extended to arrays).

Snapmaker Orca 2.3.6 Ultra

Custom fixes and feature ports on top of Snapmaker Orca 2.3.6.

Fixes

• Plate deletion no longer crashes when a background slice is running (use-after-free in BackgroundSlicingProcess)
• Sidebar combo events no longer silently corrupt the bed type or crash on long lists (bed-type handler guarded)
• Move panel alignment rows no longer overlap (Align right was hidden under Align front)

Features

• Stream tab (after Device): grid of live LAN camera streams with per-printer chips - add/remove printers, aliases, show/hide per stream, layouts from single view up to 4x4. Accepts a bare printer IP (Snapmaker U1 camera-streamer WebRTC, ~15 fps vs the ~1 fps Device-page snapshots) or any full stream URL (e.g. a go2rtc relay for Bambu cameras)
• Keep my printer when opening project files: 3MFs from other slicers no longer hijack the printer selection - the app remembers your last manually chosen (or last successfully sliced) printer and restores it silently, keeping the project's process/filament settings where compatible (Preferences > Presets, default on)
• Auto-Save project every N seconds in addition to Auto-Backup (Preferences, default off)
• Apply All filament row: set every filament slot to one preset in a single click
• Skip Settings Mapping Warnings (default on): silences the 3MF invalid-value and substitution popups; defaults/auto-fixes are applied silently
• Assemble Separately (right-click selected parts of an assembly): extract them into a new assembly without losing their position in space (port of Bambu Studio "Sub merge")
• Move panel align/distribute helpers (world coordinates): X/Y/Z align triples with Align Plate / Align Object / Align selected modes and distribute buttons (port from Bambu Studio)

Portable build: unzip and run snapmaker-orca.exe.
