    pls help don't know what to set anymore

    I'm just trying out my cnc mill to draw a 100 mm circle but the machine seems like drawing a 10 mm circle. What am I doing wrong in mach3 here?
    1 mach3 unit = 1 mm and I use mm settings.

    It sounds as though your steps per unit is incorrect....by a factor of ten...hth

    ok I think I got it now I reset the units and rebooting etc. Now I am facing backlash problem on my cnc mill. I set up my micro to 2000 steps per rev / 2.5mm (1 turn I got 2.5mm travel) = 800 steps per unit.
