BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D Printers. A precisely measures the tilt of the bed surface. It could work with any kind of bed material, such as glasses, wood, 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.
