BLTouch Sensor Guide: All You Need to Know

BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D Printers. A precisely measures the tilt of the bed surface. It could work with any kind of bed material, such as glasses, wood, metals, and so on.

BLTouch is fulfilled with simple structure and high precision by using progressively designed solenoid and hall sensors. 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.

• Features：
  The main functions and controls of BLTouch are the same as the usual auto bed leveling sensor, which consists of an RC servo and microswitch. Thus, BLTouch can be applied on almost every board.
  Self-test： The push pin operates 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. 
  
• Easy to Use: This auto bed leveling sensor makes it easier to level the hotbed, which can precisely measure the tilt of the Bed surface. Bed leveling is not a problem anymore.
• Intelligence self-check and alarm: The function of auto leveling is adopted to make it easier to use and to increase the success rate of shaping.

How to Install Creality BL Touch?

How to connect the wiring?

There are two types of BL touch wiring. One is the 32-bit mainboard and the other one is the 8-bit mainboard

32-bit
Ender-3-V2 with V4.2.7 32-bit mainboard

8-bit

✔ Step 1:  Plug in the BL touch extension cable into Pinboard A. It needs to be in the correct orientation to avoid blowing anything up, so read the label on Pinboard A and plug the BL touch extension cable in alignment.
✔ Step 2:  Pinboard A plugs into space where the LCD ribbon cable was. Take care to make sure it is centered as it is possible to plug in misaligned.
✔ Step 3:  There are three stop plugs all in a row on the mainboard, We need to find and unplug the one that has the Z label, and then insert the BL touch black and grey cables in the correct direction.
