Ender 3 Pro BLTouch firmware is a modified version of the original Ender 3 Pro firmware that allows users to add a BLTouch sensor to their printer. The BLTouch sensor is an automatic bed leveling sensor that helps to ensure that the print bed is level, which can improve the quality of prints. BLTouch firmware is available for download from the Creality website.

Second, it can save time by eliminating the need to manually level the print bed. Third, it can help to prevent damage to the printer by preventing the nozzle from crashing into the print bed.
