Unwanted engraving lines in Ortur

Community Laser Talk

So I decided to use my chuck on my laser recently, But it keeps making these laser lines for some reason. Im still doing more tape tests, but Im running out of ideas. I have no cracks in my laser lens, I have never adjusted my settings for anything.

When I use my roller, this doesnt happen at all.

If anyone can give me ideas what it could be or point me direction of where I can find some solution please let know. Ive been at this for over a week.

Speed seems rather fast.

I agree, 2400 mm/m is a little fast for a Rotary. The rotary can do it, but the jaws might be slipping.

So you have used that mug on the roller?

Cut your speed and power in half to see if it makes a difference.
