Sometimes the laser overburn and doesn't cut

Hello :slight_smile:
I have Sculpfun S9, and as you can see in the pictures, sometimes in different places the laser doesn’t cut the wood and overburns it. If I repeat the process with the same settings and vectors - it’s okay.

What can be the reason?

Do you have a screenshot of your settings?
I suggest having a look here: Settings guide - Diode Laser Wiki and maybe here in general: Quick Start & Overview - Diode Laser Wiki

The issue was from the knot of the wood :slight_smile:
