    Are you familiar with how the controls work?

    Okay. You will have to get familiar with the controls to move things around.

    Jog control button is a good place to start.

    With the machine off, reach around and turn the ballscrew by hand and see if is free. You could also move it up that way.

    While costly, I personally would probably call in a tech, you’ll learn enough to be worth it.

    Post your rough location, you really need a few hours with someone. While you can learn it yourself, education isn’t free on cncs.
