        Try using G92 A0 to set the position of the axis manually which will mark it as homed.

            @flopes do you have a nice way to attach an analog joystick to the duet 3d?

              @flopes There are CNC-pendants, which also work with Duet boards, but AFAIK they're digital. Or at least they have a digital interface to the Duet...

              //edit check here for a new analog variant
