| Software notes | Kobra OS (based on Klipper) featuring a 4.3-inch touchscreen interface. Compatible with Anycubic Slicer for color management and Wi-Fi connected for remote monitoring via app. The integrated ACE Pro system automatically handles filament changes and active drying. | 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. |
