Product Detail

Bambu Lab’s printers, including the X1 and P1 series, use proprietary firmware that extends standard G-code with custom commands for features like multi-material printing (via AMS) or high-speed control. Their wiki (https://wiki.bambulab.com) ↗️ provides basic G-code guides, but these lack completeness for custom or diagnostic codes.

Proprietary firmware running on proprietary hardware.

While open-source slicers like OrcaSlicer can prepare G-code for Bambu printers, the HD 2’s full feature set (e.g., dual-nozzle multi-material printing, AMS 2 Pro, real-time monitoring) relies on Bambu Studio or Bambu Connect, both proprietary.

The HD 2 supports LAN mode and SD card printing, allowing local control without Bambu Cloud. LAN mode uses a local network for communication (e.g., via Bambu Studio or Bambu Connect), and SD card printing bypasses networking entirely. Bambu’s wiki confirms these options (https://wiki.bambulab.com/en/x1/manual/lan-mode). ↗️ However, some features, like remote monitoring or print history, are cloud-dependent and unavailable in pure local mode.

Bambu Lab printers locked-down, encrypted firmware with signed updates.

These printers have many proprietary components - a custom, single-source mainboard and the AMS motors are two that stand out. Repairability and serviceability are poor.

This is a heavily qualified answer. Bambu Labs cooperation is reactive and inconsistent, often seeming like damage control. There is no explicit policy statement about open profiles by Bambu Labs.

Bambu Labs is notorious for attempting this. Their announcement of a firmware update that could lock out third-party control software was a major motivation for the foundation of the MFR.
