| Software notes | The native software is Bambu Studio, available for Windows and macOS, with advanced slicing and direct integration of the machine's proprietary features. The printer is also compatible with third-party slicers that export standard G-code (PrusaSlicer, SuperSlicer, Cura), though some advanced functions — including AMS control, Vision Encoder calibration, and chamber management — may be unavailable or only partially supported outside the Bambu ecosystem. | The machine is driven by Klipper firmware pre-installed on a proprietary 64-bit motherboard, ensuring rapid processing for advanced features like input shaping and pressure advance. The manufacturer provides a customized version of Cura (Elegoo Cura), but the printer is fully compatible with major third-party slicers such as PrusaSlicer and OrcaSlicer. Connectivity includes USB ports and a LAN network port, enabling remote management and direct print file transfers via the Fluidd or Mainsail web interfaces integrated into the system. |
