| Software notes | The Kobra OS, based on Klipper, supports native features like Input Shaping and is accessible via a touchscreen interface. The machine is compatible with Anycubic Slicer Next and OrcaSlicer, supporting remote monitoring via Wi-Fi through a dedicated app and managing automatic filament changes with the ACE Pro module. | 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 Kobra 3 V2 Combo if…
you value maximum colors, work area and multicolor printing. «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.»
