| Software notes | The STM32 board runs Marlin and communicates via USB Type-C or TF card; it works with any standard slicer (Cura, PrusaSlicer, Simplify3D) without proprietary restrictions. Lack of Wi-Fi requires physical transfer of G-code files, but ensures full offline control. | 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. |

Which one to choose
Choose Sidewinder X3 Plus if…
you value work area, max print speed and maximum z height. «The rated maximum speed indicates the theoretical hardware limit, not the everyday working speed. Faster machines reduce print times on simple geometries, but real-world speed depends on material, geometry, required surface finish, and slicer settings. Values above 200–300 mm/s are meaningful only on machines with CoreXY kinematics, active input shaping, and a stiffened mechanical frame.»
