BL Touch is an auto-leveling sensor for 3D Printers that can precisely measure the tilt of the Bed surface. It works with many kinds of bed materials, such as glasses, woods, metals, and so on.
Compatible with: CR-10 V2, and any printer using an 8 Bit system.
The main functions and controls of BL Touch are the same as the usual auto bed leveling sensor, which consists of an RC servo and microswitch. Thus, BL Touch can be applied on almost every board.
BL Touch 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.
Self-test: The push pin operates 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.
