    Exclamation edged part

    Hi;
    I have one of those Toshiba 4 axis stepper driver board from ebay which is controlled by
    mach3 program.i have a good power supply for that.
    my retrofit mill is from central machinary that I am using it as a CNC.
    here is the problem:

    the parts i cut has depth line like steps on it and every layer that is cut is a little off from previous one.
    seems like if i cut squire pocket top and left side has sign of steps but right & bottom side is clean cut.

    I am not sure if i lose some steps or there is other reasons involved.
    the part i am cutting is plastic and the feed rate is 6 IPM at 1400 RPM with 1/4 endmill.
    is there anybody the knows the resone(s) and solutions for this problem?

    Thanks

    Sounds like you spindle is out of tram with your table.

    Search Google for more information about tramming.
