Awesome, thanks! I think this would be valuable information for the wiki - there's not enough there on how to set up the bltouch with the Maestro. I'm still new to the Duet boards and quite a ways off from getting mine running else I'd add some content there

@dc42 said in Duet 2 Maestro BLTouch Wiring:

You should be able to connect the BLTouch entirely to the Z probe connector. The 5th pin on the Z-probe connector provides +5V, and you can use the MOD pin on the Z probe connector as the servo pin.

The BLTouch seems to have two GND pins - one for the z-probe, another for the servo.

Can I use the +3.3v pin on on the z-probe connector as the second GND?
