Software notes The STM32 board runs Marlin and communicates via USB Type-C or TF card; it works with any standard slicer (Cura, PrusaSlicer, Simplify3D) without proprietary restrictions. Lack of Wi-Fi requires physical transfer of G-code files, but ensures full offline control. 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.
