Cloud dependency No No
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 operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks.
