The BL-Touch Auto Bed Leveling Sensor is a popular upgrade for 3D printers. It uses a sensor to measure the distance between the print head and the heated bed, and then automatically adjusts the Z-axis height during printing. This ensures that the first layer is always laid down correctly, even if the bed is not perfectly level.
