    movement varies

    hi guys
    I am trying to set up a cordinate table running mach 3 but am have trouble getting the same movement all the time eg set to move 100mm and it will move 99.75 the first time next time it will move 99.48 etc I have set the motor tunning using the setting page.I have noticed that the feed rate varies as the head moves is this part of the problem.

    Question You have..

    You may have backlash and/or losing steps.
    When you move a long way from 0,0 and go back to do end up at the starting point (0,0) ?
    Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
