Software notes Native Klipper firmware with a 64-bit ARM 1.5 GHz processor. The printer is controlled via Wi-Fi from the Fluidd or Mainsail web interface, sending G-code from any slicer (Cura, PrusaSlicer, OrcaSlicer). No proprietary software required; USB/Type-C connection allows offline control. The user has full access to macros and advanced Klipper tuning, without hardware modifications. The A1 works natively with Bambu Studio, Bambu Lab's proprietary slicer available for Windows and macOS, which handles slicing, automatic calibrations, and remote monitoring via the Bambu Handy app. Third-party slicers — including PrusaSlicer, SuperSlicer, and Ultimaker Cura — are supported via standard G-code export, but advanced features such as vibration compensation and active flow control are only available within the Bambu ecosystem.
