The BLTouch is a 3D printer auto leveling sensor that measures the surface tilt precisely. You can use it with any kind of bed material, such as glass, wood, metal, etc.
BLTouch has the same functions and controls as a normal auto-leveling sensor, which consists of an RC servo and a micro switch. As a result, BLTouch can be applied to almost any board.
Due to the use of progressively designed solenoid and hall sensor, BLTouch has a simple structure and high precision. By adding many smart functions, such as self-test, alarm, alarm release and touch switch mode, blue LED for servo signal indicating, and Z-probe (Zmin) testing, it strives to make printing easier and more enjoyable for users.
