Burn in with 22W laser

I upgraded the Sculpfun S9 with a 22W laser head and now the burn appears at the start of every cut. I didn’t have this problem with the 5W laser. Is there any solution?

You have a lot more power now :slight_smile: There are different ways to tackle this.

  • Use less power and more passes
  • Use lead-in and lead-out feature
  • Use dynamic power (though not the best option for cuts)
  • your material is also supporting this effect because it’s so bright. You will need to clean it afterwards anyhow.
