Hi, I'm using a duet 2 Wi-Fi, I've checked the wiring a lot of times, I did the alterations needed on the firmware to make the bl touch work and nothing...
So presuming that I'm doing something wrong i decided to make a new reprap firmware but with bl touch and the same thing happened, the bl touch deploys and retract with M401 and M402 but when I home z the bl touch deploys and don't retract when something touch it, as if it doesn't recognize the z endstop.
I checked the black and white wire and they are good.
If i try to home z without the z endstop connected on the "IN" and "OUT" pins from the duet I have an error.
I presume that is something about the firmware that I'm doing wrong, any hint?
Ps: I tried with other bltouch and it didn't work
