      I've been trying to upgrade my old BitsFromBytes 3D Touch printer to a Duet Wifi board for some time now. I've got things mostly dialed in to where they should be, at least it prints now, sort of. When I home the axes, it zeros the head in at the back left corner of the print bed, where the endstops are. But when I tell it to print anything, the head zooms off to the opposite front right corner of the bed and starts the print there.
      The real problem is that it only prints the left half of the object, it's as if the right half was clipped off by the limit of the X axis. I used to be able to specify where on the bed the object printed in Kisslicer, but now no matter what it goes to the front right corner every time.

        1. Please post your config.g file and your homing files.

        2. How large is the bed?

        3. Have you checked that after homing, if you use the jog buttons in the web interface to move the head e.g. 100mm in the +X direction, the amount of movement is correct i.e. 100mm ?

          Here is my config and homeall for my CubeX Duo should be similar.
          I also have the same for my Trio with a Z probe if you need that.

            And the answers to my other questions?

            2. How large is the bed?

            3. Have you checked that after homing, if you use the jog buttons in the web interface to move the head e.g. 100mm in the +X direction, the amount of movement is correct i.e. 100mm ?

            Also, please post the first 50 or so lines of the GCode file so we can see where the print is supposed to be centred.
