The Original Prusa i3 MK2 is a 3D printer that has been designed and manufactured by Prusa Research, a Czech company founded by Josef Prusa. The firmware of the printer refers to the software that controls the hardware and enables it to perform its functions.

One of the key features of the Original Prusa i3 MK2 firmware is the automatic bed leveling feature. This feature allows the printer to detect any variations in the level of the print bed and compensate for them automatically, resulting in a more accurate and consistent print. The firmware achieves this through the use of a sensor that is mounted on the printer’s print head.

Another important feature of the firmware is the power loss recovery feature. This feature allows the printer to resume printing from where it left off in the event of a power outage or other interruption. This is achieved through the use of a backup power supply that provides the printer with enough power to save the print progress and safely shut down. The firmware also includes a variety of other features, including the ability to print from USB, SD cards or over Wi-Fi, support for multiple filaments, and a user-friendly interface that can be accessed through a display screen on the printer.

The Original Prusa i3 MK2 firmware is a reliable and feature-rich firmware that is specifically designed for the Original Prusa i3 MK2 3D printer. Its open-source nature allows for continuous improvements and modifications, making it a popular choice for 3D printing enthusiasts and professionals alike. According to Mr. Josef Prusa, “The Prusa i3 MK2  printer can automatically find the calibration points, and because it knows its geometry (how skewed the axes are), it can correct it live during the print as it does with automatic mesh bed leveling.” The Prusa i3 MK2 is open source, and the firmware is available.
