BLTouch - Automatic Bed Leveling Probe


In stock, ready to ship.

Current version: v3.1

Cable available here if needed: 

The official BLTouch from ANTCLABS is an auto leveling sensor for 3D Printers that can precisely measure and correct the surface tilt of any kind of material, including glass, wood, metal, tape, BuildTak and so on. 

BLTouch is easily calibrated and highly precise. It uses a progressively designed solenoid and hall sensor and its smart functions such as self-test, alarm, alarm release & Touch Switch mode, Blue LED for servo signal indicating and Z-probe(Zmin) Testing provide great user convenience.

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


  • Self-test : The push pin is operated three times to test when the power is on
  • Alarm : The LED light blinks if a problem found on a self-test or on an operation


  • BLTouch’s Standard Deviation in repeatability is around 0.005mm, at that precise.  (refer to attached video)


BLTouch consists of Atmel ATtiny13A, solenoid, and a push pin.

Innovative Solenoid: Ultra Power Saving

On idle state, while the push-pin is whether pulled out or retracted, there are not any electric current flowing on solenoid, and standby electric current in the whole device is below 15mA on average, whereas on working state, while the pin is moving in sudden about 100ms, under 300mA flows in the device.

Low power consumption even further drops joule heating, preventing from heat problem.

Hall Sensor: Free Bed Selection

BLTouch does not uses either optical, nor proximity(inductive/capacitive) sensor.

BLTouch is controlled by hall effect, providing high precision. Thus the bed material can be selected freely
