| Software notes | Anycubic Kobra OS (a closed Klipper-based system) compatible with the Anycubic mobile app for remote control. Supports all major 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 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.»
Choose Neptune 4 Max if…
you value work area, maximum z height and native klipper. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
