Description

BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D printers. It is an auto-leveling sensor for 3D printers that can precisely measure the tilt of the bed surface. It could work with any kind of bed material, such as glasses, wood, metals, and so on.

The main functions and controls of BLTouch are the same as the usual auto bed leveling sensor. It consists of an RC servo and microswitch. Thus, BLTouch can be applied on almost every board.

BLTouch is fulfilled with simple structure and high precision by using a progressively designed solenoid and a 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 (Z-min) testing.

Compatible with 3D Printer:

Compatible with 8-bit (V1.1.4 and V1.1.5) or 32-bit (V4.2.2 and V4.2.7) Controller Board

 

If you have an older 8-bit board (Green PCB with board version of V1.1.4 or V1.1.5), please check the video by Johnson Lam from KakiDIY:

 

 

If you have a newer 32-bit board (Black PCB with board version V4.2.2 or V4.2.7), please check this tutorial. However, please make sure you swap the ORANGE and YELLOW wires on the 3-pin connector:

 

Make sure to insert both the red connector (2-pin) and the black connector (3-pin, with orange and yellow wires swapped) to the 5-pin socket on the 32-bit board. Again, do refer to this tutorial for detailed steps.

 

For firmware installation, you can refer to this video by 3DPrintscape:

Features:

  • Genuine BLTouch from Antclabs.
  • Comes with 150cm length cable, terminated with connector for 8-bit and 32-bit (requires minor wiring modification) controller board.
  • Comes with Programmer, Adapter for 8-bit (V1.1.4 or V1.1.5) board.
  • Comes with cable ties (tidy the cabling), screws, and Ender 3 BLTouch mounting bracket/rack.
  • Innovative solenoid: ultra power saving
    • On idle state, while the push-pin is whether pulled out or retracted, there is no electric current flowing on the solenoid. Standby electric current in the whole device is below the average of 15mA on working state, but while the pin is moving, in a sudden time about 100ms, under 300mA flows in the device.
    • Low power consumption even drops joule heating, and it prevents overheating problems.
  • Hall sensor: free bed selection
    • BLTouch DOES NOT use optical nor proximity (inductive/capacitive) sensor.
    • BLTouch is controlled by the 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 the existing RC Servo motor signal, so just plug BLTouch on the same pins after removing the servo motor.
  • Smart
    • Self-test: The push pin operates two times in a test when the power is on.
    • Alarm: The controller 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.
  • Used for Creality 3D Ender 3/Ender 3 Pro/Ender 5/CR-10/ CR-10S/S4/S5 CR20/20Pro (Creality V1 Firmware Parts conclude the V2)
