| Software notes | The printer works with Anycubic Slicer Next, derived from OrcaSlicer and optimized for the Anycubic ecosystem; it supports multi-plate management and object skipping during printing. Remote control and real-time monitoring are available through the Anycubic app (iOS and Android), connecting via LAN or cloud. The proprietary firmware is not currently open source; native Klipper compatibility is not supported. | 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. |
