@droftarts lol, thank you very much

I have a odd problem that started with my duet 2 WIFI ,every time I plug in my bl touch to the z endstop my WIFI disconnects. If i unplug it,the wifi immediately connects again. I had a house fire and haven't used the printer in some time and i can not seem to remember how i had it set up, it all used to work just fine except i never figured out why the z offset would be perfect until i started a print and then it would try to print 3 inches off the bed. It was a new mercury one build i started 2 years ago i never quite finalized that I want to try and finish. Did i plug the bl touch in wrong this time? I have the power and ground running off the expansion and the 3rd wire on pin 8 (heater3) and the other 2 wires plugged into my z endstop.
