Just added the klicky to my RR 3.1 500 and the klicky does everything fine. Z home, z tikt, bed mesh, stow and deploy. When I print I get the above error after the inital home and heating before print, extruder moves to do the pre print blob and the error comes.
The probe is infact attached as this point. I would of expected it to detect before it does the blob and I think that is the error
