Software notes Managed via Kobra OS with support for the Anycubic App over Wi-Fi and standard USB interfaces. Compatible with major market slicers. 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.

Which one to choose

Choose Kobra 2 Plus 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.»

Choose Neptune 4 Max if…

you value work area, native klipper and maximum z height. «Klipper is an open-source firmware that offloads trajectory calculations from the microcontroller to a host computer, enabling all advanced features including input shaper and pressure advance. Native support eliminates the need to replace the firmware, a process that voids the warranty on some machines. Relevant for users who intend to tune advanced parameters; for basic use the difference from Marlin is minimal.»
