    Exclamation Uneven engraving on ABS material

    Hi,

    I have a Chinese laser co2 60w machine. Lihuiyu controller with CorelLaser
    Everything was fine for a small period of time, and now I have a problem.

    The engraving is uneven (you can best see it on white material) There are places where it burns more material and places where less material is burned. (engraved deeper)
    I mainly engrave ABS dual layer material.
    I did some research and my guess the laser tube or power supply for the laser tube or the material
    I also checked so that the lens is not loose or moving inside the laser head.

    I attached a picture.

    Can someone tell me what is the problem. What should I replace?

    Thank you!

    unstable level of power from laser source way above 5.00% with the combination of low resolution optics/lenses 100um and above installed in the machine. Kind Regards.

    Thank you for your message. Should I try and change the laser power source?
