Ender 3 Pro BLTouch Firmware 4.2.2 is a firmware update for the Ender 3 Pro 3D printer that enables the use of a BLTouch auto bed leveling sensor. BLTouch is a sensor that automatically measures the distance between the print bed and the nozzle, and adjusts the Z-offset accordingly. This ensures that the first layer of a print is evenly distributed and well-adhered to the bed, which can significantly improve print quality.
The Ender 3 Pro BLTouch Firmware 4.2.2 update is available for download from the Creality website. Once downloaded, the firmware can be installed on the Ender 3 Pro using an SD card. The installation process is relatively straightforward and should only take a few minutes to complete.
