| Software notes | It runs Kobra OS (based on Klipper) with a 4.3-inch touch interface. It is compatible with Anycubic Slicer for color management and connects via Wi-Fi for remote monitoring through the app. | The STM32 board runs Marlin and communicates via USB Type-C or TF card; it works with any standard slicer (Cura, PrusaSlicer, Simplify3D) without proprietary restrictions. Lack of Wi-Fi requires physical transfer of G-code files, but ensures full offline control. |
