I am having a horrible time with the DUET. I have had no issues this weekend with setting up the probe. The probe never hit the bed. Today, while I am still trying to get my first print, now when I do home all or home Z, it moves the bed, I see the probe value change from 0 to my target of 940. It slows down and then continues to move until it hits the bed and I have to shut the printer off to kill the movement. Here is my conifg file.

;*** If you are using axis compensation, put the figures in the following command
M556 S78 X0 Y0 Z0 ; Axis compensation here
;
T0 ; select first hot end

Any help would be appreciated. I have a make gear M2 that is marlin based so I know that and printers. Just don't know what is going on with this.
