Software notes Artillery OS, a Klipper-based system. Compatible with standard slicers like Cura, PrusaSlicer and OrcaSlicer via G-code. Supports Wi-Fi transfer, SD card and touchscreen control. Compared to closed platforms, it allows advanced adjustment of printing parameters, but lacks a native cloud ecosystem and requires manual slicer configuration. 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.
