| Software notes | Compatible with the main slicers on the market. It supports cloud connectivity via the Anycubic app and Wi-Fi for remote monitoring, while still allowing offline use via USB. | 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. |
