Software notes	The A2L is compatible with Bambu Studio, Bambu Lab's proprietary slicer for Windows and macOS, which provides native access to all machine features including AMS multi-color management. Third-party slicers that export standard G-code — such as PrusaSlicer and OrcaSlicer — are supported, though some advanced features may not be available outside Bambu Studio. Connectivity is via Wi-Fi; basic printing functions do not require a cloud account.	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.
