Hello,

 

I have been getting several questions about the PIN 27 adapter board when using the Creality 4.2.2 and 4.2.7 boards. You do NOT need the adapter board if you have the newer 32 bit Creality motherboard. Below is an example connection of BLTouch if you have these boards.

 

Board-----BLTouch wires
G---------Green----Servo
V---------Red------Servo
IN--------Yellow---Servo
G---------White----Probe (if it doesn't work, try to swap with Black)
OUT-------Black----Probe (if you are using Z_MIN_PROBE_PIN 17, if you don't, please just uncomment Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN as above)

Here is a method for another BLTouch version and the Z- endstop way. This is the verified method that I have had customer's of my firmware service use successfully.
