BLTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on. Features Main functions and controls of BLTouch are the same as usual auto bed leveling sensor, consists of RC servo and micro switch. Thus, BLTouch can be applied on almost every board. BLTouch is fulfilled with simple structure and high precision by using progressively designed solenoid and hall sensor. 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. Smart Self-test : The push pin operate two times in a test when the power is on. Alarm : The AI will flash the LED indicator if a problem is detected during a self-test or operation. Wiring defect indicator : Blue and Red LED for indicating wiring defects. High-precision BLTouch’s Standard Deviation in repeatability is around 0.005mm, at that precise. Engineering plastic(PC) push Pin Engineering plastic pins are safer than conventional metal pins.
