I figure I would just post this for any other idiots like myself trying to hookup the BLTouch to the Duet v0.6. Strangely enough it works without hooking up the Black Ground wire as shown on ANTCLABS's website.

@cadsys Ok I got it working by moving the control wire to physical pin 21 as shown on ANTCLABS's website. I finally found the correct pinouts here: https://reprap.org/wiki/Duet_pinout for the 0.6 board. It shows heater 3 on pin 21. Deploy and retract now working via M280 commands.

@droftarts Yes. It does deploy and retract at startup.

I don't have a config-override.g

@Phaedrux Ground wire makes sense to me too, just strange that on ANTCLABS they show it disconnected.

Yes it turns on, solid red LED, and performs the self test. It's unresponsive to codes. My config.g is setup by default to use heater3 like all the info online says to use but I don't think this is right for the v0.6 board because the expansion pins are totally different.

@droftarts I am trying to use the latest BL Touch v3.1 with the Duet .6. I have updated and verified the firmware is 1.26.1. I also used the online tool to update my config.g. I have tried several different wiring configurations and still no response when sending M280 codes to deploy the pin. I think my wiring is incorrect. Do I hook up the black wire ground from the BL Touch or not? The diagram on the ANTCLABS website show it disconnected for the Duet. Is this correct?
