Key Features BLTouch is an auto leveling semiconductor hall sensor for 3D Printers based on open-source. Simple, Smart, & Precise with repeatability is around 0.005mm. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on. Longer Stroke: Up to 1.6mm longer than V2.0 BLTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. Main functions and controls of BLTouch are 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 can be easily applied, since it has a small and simple structure. The BLTouch 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. Gathering information & setting up your firmware will be an easy task. For some boards, upgrading to V3.1 can be done without firmware modification.Smart Technology: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.
