BLTouch - Automatic Bed Leveling Probe

$ 37.98

The authentic BLTouch sensor made by ANTCLABS in South Korea! The BLTouch is a touch-based 3D printer bed leveling probe which enables automatic bed leveling on your 3D printer, regardless of print surface. Other machines that use inductive sensors require specific bed surfaces, or can only probe at certain spots on the bed. This touch sensor works perfectly with any surface, from glass to blue tape or BuildTak. It makes calibration a breeze - simply press calibrate and your machine does the rest. Current Version: 3.1

BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D printers.
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.


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.


BLTouch can be easily applied, since it has a small and simple structure. As BLTouch works as usual auto bed leveling sensor, Gathering information & setting up your firmware will be an easy task.


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.


BLTouch’s Standard Deviation in repeatability is around 0.005mm, at that precise.

​Logic Voltage Free(Open Drain Output)
3.3V / 5V logic voltage free(default).

​Long stroke : ≒ 6.5mm
The stroke is up to 1.6mm longer than V2.0
