BLTouch (Original) - Auto Bed Leveling Sensor | 3D Printer

BLTouch (Original) - Auto Bed Leveling Sensor | 3D Printer
BLTouch is an auto leveling touch sensor for 3D Printers based on open-source. It could work with any kinds of bed materials, such as glass, woods, metals, and so on. This product features the Original BLTouch Sensor, made by Antclabs and no imitation.


Features

Main functions and controls of BLTouch are same as usual auto bed leveling sensor, consists of RC servo and micro switch. Thus, BLTouch can be applied on almost every board. BLTouch fulfilled simple structure and high precision by using progressively designed solenoid and hall sensor, and aimed user convenience and enjoyable printing by adding many smart functions, self-test, alarm, alarm release, test mode for M119.

Simple
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.

Smart
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

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

Technology

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.

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