    Does anyone could give me some hint or suggestion on the below problem:

    Today I fixed the clogging problem, then try to restart the printer. Then Z axis won't go home, X and Y axis is perfect on home. It simply stopped in the middle for Z axis, and is still 2-3 inch high from the printing board.

    When it starts to print, the head is simply working in the middle of air.

    Could any one tell me how I could solve this problem?

    By the way, I am using Robo R1+ with Matter Control.

    Thanks. IMG_1927.JPG

    Likely the home switches (on the Z) are out of place. Pictures of both of them? Make sure the wires didn't come off.

    Finally I solved the problem. Actually I found that I made the mistake as there is some stuff behind which is blocking Z axis to lower down further.

    Thanks.
