| Software notes | Powered by CrealityOS, a Klipper-based firmware, it supports remote control via Wi-Fi or LAN and interfaces natively with Creality Print and other compatible slicers for advanced multi-color workflow management. | 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 K2 Combo 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.»
Choose Neptune 4 Pro if…
you value price and max bed temperature. «A heated bed reduces the thermal gradient between the part and the environment, limiting warping and delamination. Up to 60 °C covers PLA and flexible materials. Between 80 and 110 °C it enables PETG, ABS, and ASA. Above 110 °C it is necessary for PC and high-temperature technical materials. Bed temperature should be evaluated alongside nozzle temperature: a high-rated bed adds little value if the nozzle cannot reach the corresponding threshold.»
