    My old PC died, and the Robo3d set unused for a few months. Now I got it back up and running but on 8 out of the 9 points on auto leveling it touches the bed with no issue on teh back far left point it's in the air about an inch or so never touches.

    Not sure what to do as the it's just one of the back points, and when it starts printing the piece it's starting mid-air.

    It's the one thats up at 5.03


    <-Bed x: 110.00 y: 20.00 z: -0.22
    <-Bed x: 205.00 y: 20.00 z: 1.20
    <-Bed x: 205.00 y: 125.00 z: 1.34
    <-Bed x: 110.00 y: 125.00 z: -0.13
    <-Bed x: 15.00 y: 125.00 z: -0.97
    <-Bed x: 15.00 y: 230.00 z: 5.03
    <-Bed x: 110.00 y: 230.00 z: 0.13
    <-Bed x: 205.00 y: 230.00 z: 1.55

    If it is not touching the bed then something is false-triggering one of the Z switches so that it THINKS it touched the bed. You know this is true because Marlin simply tells it to go down until it touches the bed at each of the 9 leveling points. It does this (or thinks it does). One of those switches has to be getting tripped or it will not register on the bed.*

    Watch this... If that doesn't help you sort it, let us know what you checked with respect to the Z switches.






    *there is the small chance it is a bad board, but really tiny :)

    Thanks, rotated the left rod a bit and started touching the back now, tried a test print of the calibration box and it's printing on the front left square on the front left of the bed. Odd.

    Front corner is the default HOME so that is normally where a print starts (R1 series at any rate).

    You can center it wherever you like in the slicer view when you do the slice.

    Thanks, didn't notice that on all the prints previously. they must have had center already setup.

    Sure, X = 0, Y = 0, Z = 0 is home by default in most software :)
    That happens to be the corner on the Robo R1
    Whichever software you use you should be able to change the geometry for the printer (which includes details like that).
