    Strange cutting pattern

    Romos, (or others)

    Any ideas why when I cut thicker metal I get the pattern shown here?

    The cut starts by forming a hole, as the cut proceeds it then makes a good clean line.

    I tried adjusting the amount of time the laser gets to start the cut, and I also tried adjusting the pressure of the oxygen.

    What thoughts?

    This is normal.
    To cut a clean part, use in your file, Lead in/out.

    That's discouraging, I didnt know the cut would work that way.

    So you are suggesting making a point of entry into the cut? I give an example of making a circle in my drawing.
