BL Touch -SR

BLTouch 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.

Features

Main functions and controls of BLTouch are the same as usual auto bed leveling sensors, consisting of an RC servo and micro switch. Thus, the BLTouch can be applied on almost every board.

BLTouch uses a simple structure to create high precision by using a progressively designed solenoid and hall sensor. It aims to be user convenient and allow for 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.

​Smart
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.

High-precision
BLTouch’s Standard Deviation in repeatability is around 0.005mm, quite precise.

Technology
BLTouch consists of Atmel ATtiny13A or ATtiny2313A(V2.2 and later), 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 no any electric current flowing on solenoid. Standby electric current in the whole device is below average of 15mA on working state,

but while the pin is moving, in a sudden about 100ms, under 300mA flows in the device.

Low power consumption even drops joule heating, and it prevents 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 freely selected.


Optimized structure : Larger Build Size
BLTouch is a small, and technology-intensive device. Build size can be set larger than other existing auto bed leveling sensor.

Easy to Use
BLTouch uses existing RC Servo motor signal intactly, so just plug BLTouch on the same pins after removing servo motor.
