| Software notes | The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media. | It comes with the proprietary Snapmaker Luban software, a free, unified application available for Windows, macOS, and Linux. Luban is tailored to fully utilize the independent dual extruders (IDEX), integrating ready-to-use profiles for various print modes (Copy, Mirror, Backup). Compatibility with major third-party slicers, such as Cura or PrusaSlicer, is also ensured via standard G-code export. Direct machine control is facilitated by the integrated Android-based touchscreen display and Wi-Fi connectivity for remote management. |
