Features: 100% brand new and high quality BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D Printers. BL Touch is an auto-leveling sensor for 3D Printers that can precisely measure the tilt of the bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on. BLTouch is fulfilled with simple structure and high precision by using progressively designed solenoid and hall sensors. It aims for user convenience and enjoyable printing by adding many smart functions, such as self-test, alarm, alarm release Touch Switch mode, Blue LED for servo signal indicating, and Z-probe(Zmin) Testing. The main functions and controls of BLTouch are the same as the usual auto bed leveling sensor, which consists of an RC servo and microswitch. Thus, BLTouch can be applied on almost every board. Intelligence self - check and alarm: The function of auto leveling is adopted to make it easier to use and to increase the success rate of shaping.
