Software notes The printer is operated through Bambu Studio, Bambu Lab's open-source slicer based on PrusaSlicer, available for Windows, macOS, and Linux. Remote control is available via the Bambu Handy app or Bambu Suite. The machine includes a 5" color touchscreen for local operation and connects over dual-band Wi-Fi. The firmware is proprietary; Klipper is not natively supported. The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer.
