Software notes Prusa firmware based on Marlin, fully open source, with built-in input shaper for faster and cleaner prints. Official slicer: PrusaSlicer (free, optimized profiles), compatible with Cura and Simplify3D. Control via USB, Ethernet or Wi-Fi with Prusa Connect (optional). No filament DRM: full freedom to use third-party materials. 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.
