Software notes The proprietary Elegoo OS, built on Klipper architecture, manages full-auto calibration routines and AI-assisted monitoring. The machine is primarily supported by Elegoo Slicer (an Orca Slicer derivative), ensuring optimal control over material profiles and dynamic color changes. Users can also natively use Orca Slicer or export G-code from third-party alternatives like Cura. The intuitive touchscreen and Wi-Fi connectivity enable seamless remote management and direct job queuing over the local network. 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.

Which one to choose

Choose Centauri Carbon 2 if…

you value maximum colors, closed chamber and work area. «The maximum number of colors indicates how many distinct color zones or materials can be used in one print without manual intervention. Two colors cover most practical uses, including soluble support. Higher values are useful for complex decorative models or color-coded prototypes. Each additional color increases print time due to transition purges, so the practical benefit should be weighed against the added time cost.»
