| 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. | Compatible with Artillery Slicer and Cura; the Marlin firmware accepts standard G-code, so it works with PrusaSlicer, SuperSlicer, OrcaSlicer. WiFi file transfer does not offer a Klipper web interface, limiting remote monitoring and real-time adjustments. |
