| Software notes | Compatible with the main slicers on the market. It supports cloud connectivity via the Anycubic app and Wi-Fi for remote monitoring, while still allowing offline use via USB. | 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. |
