    Default machine looses position in X axes

    hi i am new to this forum
    was hoping to get some help with my older MS CNC JR vertical milling machine
    the machine loses tracking ever so often in the x axes
    totally random so is the amount of of position loss
    the amount is anywhere from .002 to .0049"
    it usually happens on the beginning of the milling cycle or end never in the process

    any help would be greatly appreciated

    DS

    It sounds like lost steps, which happens when steppers try to go too hard or too fast. You might try turning down the acceleration on the axis that's failing. It could be due to a lubrication failure, or it could be a coupler that's slipping.
