Cloud dependency No No
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. PrusaSlicer (optimized) and Prusa Connect for remote control. The machine accepts G-code from any slicer (Cura, Simplify3D) and communicates via USB, Ethernet or Wi-Fi using an open Marlin-based protocol. Compatible with OctoPrint and offline management. Does not require a Prusa account to print, unlike machines with proprietary firmware that block features without connection.
