Features:
Main functions and controls of BLTouch are the same as usual auto bed levelling 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 (Z-min) Testing.
Self-test: The push pin operate two times in a test when the power is on.
Alarm: The LED light blinks if a problem was found on a self-test or during operation
Wiring defect indicator: Blue and Red LED for indicating wiring defects.
