Software notes The operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks. 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.

The differences that matter
