Software notes The firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for core printing functions. The machine relies on an architecture based on Klipper firmware, which provides advanced computational performance and native features like input shaping to reduce vibrations during high-speed movements. Users can interface via the integrated 5-inch touchscreen or through the standard Klipper web interface. The recommended official slicing software is QIDI Studio, a program derived from PrusaSlicer and Orca Slicer, optimized to leverage the machine's profiles and proprietary print parameters. However, the system maintains an open approach and is fully compatible with third-party slicers such as Orca Slicer, PrusaSlicer, and Cura, ensuring maximum flexibility in the daily workflow.
