Software notes The P1S is managed through Bambu Studio, Bambu Lab's proprietary slicer available for Windows, macOS, and Linux, or via OrcaSlicer, the widely adopted open-source fork that provides finer parameter control. The Bambu Handy mobile app enables remote monitoring and print launching. The printer supports local LAN connections without a mandatory cloud account, though some advanced features — such as remote timelapses and OTA firmware updates — require a Bambu 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.
