| Software notes | The Kobra OS firmware is based on Klipper and controlled via a proprietary touch interface. The official slicer is Anycubic Slicer Next (derived from OrcaSlicer, available for Windows and macOS), but it also supports third-party OrcaSlicer. Remote control is possible via the Anycubic app (iOS/Android) over a local network, with no mandatory cloud connection for daily operations. | The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer. |
