Due to the wide variety of motherboards, the manufacturer has prepareda guideto help you install the BLTouch sensor.


Antclabs BLTouch - auto-leveling sensor for 3D printers.

BLTouch posiada 5 wyprowadzeń w postaci odłączanego przewodu

BLTouchhas 5 leads in form of detachable cable.

Sensor pinout description

To connect the BLTouch sensor you need to use five leads, divided into two plugs with three and two connectors:

  • Orangewire: I/O pin for control (PWM or software PWM)
  • Redwire: Power supply 5 V
  • Brownwire: GND
  • Whitewire: I/O pin for Z min (endstop / Z-probe)
  • Blackwire: GND

Most motherboards have their own_SERVO pin to which the BLTouch can be connected. Since each_SERVO pin has its own number, the sensor will be controlled by the number as follows:

  • M280 P0 S90 ← SERVO0_PIN
  • M280 P1 S90 ← SERVO1_PIN
  • M280 P2 S90 ← SERVO2_PIN

For some motherboards it may be necessary to re-solder the components and update the software. Please refer to theuser manualfor details.

Question: Hello, does the sensor fit the 4.2.2 motherboard in ender3 pro?
Answer: The BLTouch sensor can be mounted on this motherboard. I am uploading a short video with instructions below.

Question: Good day. I have a Creality Ender-3 V2 printer purchased from you. Do I need to buy a separate pin to install this sensor (also available on your website)? Is the cable supplied with the sensor sufficient to connect the sensor to the printer or do I need to buy an additional cable, and if so, in what standard: SM-DU or SM-XD? Greetings. SB
Answer: Instructions for installing the sensor in this model of the printer can be found in this video, among others: https://www.youtube.com/watch?v=bYW6LY-2rlo
The most important point can be seen in 2:17 there is how to connect the sensor using the standard cable that comes with the kit (you need to pay attention to the correct order of pins), I send you a description of the cable leads:

Brown - Ground (-)
Red - 5V
Orange - Servo signal
Black - Ground (-)
White - Z min signal (Out)

BLTouch from Antyclabs doesn't quite have a matching plug for Creality boards (they have a slightly different type of plug), but the solution from the video mostly works.
