| 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. | 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. |
