Software notes The operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks. 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.
