OrcaSlicer — BambuNetwork edition

This version of OrcaSlicer restores full BambuNetwork support for Bambu Lab printers. You are not limited to LAN only — it works over the internet just like before, through BambuNetwork, with full functionality for normal use and printing.

Installation

Windows

Windows requires WSL 2. Before the first launch, open Command Prompt or PowerShell as Administrator and run:

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Restart Windows, then launch Orca Studio.

Linux

A normal installation is enough.

macOS

Supported on both Apple Silicon and Intel. On first launch OrcaSlicer auto-installs a small Lima VM (orcaslicer-bambu-network) that runs the Linux BambuNetwork plug-in under a native x86_64 Linux guest. You'll be prompted to install the runtime when you launch the app for the first time; accepting will:

• install Lima and qemu-system-x86_64 via Homebrew if they're missing,
• bring up an Ubuntu x86_64 VM in the background,
• copy the BambuNetwork payload into the VM.

Once the runtime is ready, log in to Bambu Cloud normally — printers, camera preview, and Send-to-Printer (cloud or LAN) all work as on other platforms.

Notes:

• The first runtime install downloads an Ubuntu cloud image and takes a few minutes; subsequent launches are immediate.
• Building from source on macOS 15 (Tahoe) is supported via ./build_release_macos.sh. Ninja is the default generator; -x switches to the Xcode generator if you have a full Xcode.app install.

BMCU

The BMCU companion firmware is also encouraged. The firmware lives in a separate repository in jarczakpawel's GitHub account.
