    Default Fiber laser - not smooth engraving

    Hello,

    I have a Raycus 50wt + 200*200 table.

    Material: Stainless steel painted with black powder polymer paint.
    A task:
    Get a uniform bright engraving.

    The parameters were selected for that engraving:
    - 2 passes:
    Line Width - 0.05
    90power\400speed\20freq\0angle
    - 2 passes
    Line Width - 0.05
    42power\2000speed\20freq\90angle

    Engraving goes well, but uniform engraving does not always go well, there are always lines with different shape of color in different places of engraving, I think its probably knocks out more material or I am mistaking with this.
    And sometimes it’s good, there is no lines at all, and sometimes there are in different places. I already tried to change different modes, angles - the problem does not go away (
    Please tell me how to solve the problem.
    Thanks in advance for your reply.

    It looks that the powder haven't been cleaned clearly.Try higher power,higher speed and 0angle.
