    Hi,

    That would be the scale factor in the screen for 'Program Run' just to the left of the toolpath display. Remember to press the Enter key after entering a scale to make the change persist.

    Cheers

    Please check steps per .
    it is very important for the machine ,if steps per is not right ,the real distance of the machine will be not correct .
    here is a way to test and adjust it .
    1,please make a design ,let the machine move 100 mm(or more ,if your machine very big .)
    2,use a ruler measure the real distance.
    3,Compare the difference between actual and design values。
    FOR EXAMPLE .
    you let y axis move 200mm (the screen show .)
    but the real distance is 180mm( the ruler measure .)
    and now our steps per is 104.37.
