Wiring BL Touch to Duet 3 Mainboard
-
Hello,
Would someone mind explaining the best way to wire the BL Touch sensor to the Duet 3 mainboard? I haven't seen documentation specific to the duet3.

@droftarts thanks for leading me to the right place, was very helpful. Based on the link I've found the following:
I just have one question though. There are 5pins on the BL Touch connector and 5 pins on each of the possible (PWM compatible) IO headers 4,5, and 7. But because we are not connecting to the 3.3V pin and instead require 2 ground connections (black and brown in my case). Should one connect the extra ground connection to a random vacant IO header? Or is there a better way?

You can double up the ground wires, or some people connect them closer to the BLtouch and just run the one wire, or some people only use a single ground wire.
