Over burn marks/indentions at start and stop points

I’m trying to cut some 1/16" maple hardwood and in the oval shape where the laser starts and stops I’m getting a slight indention and “over burn” mark. Since I’ve never cut this material before I thought I just needed to play with the settings, but everything I’ve tried results in the same issue. What could be the problem here?

Laser on/off timing is not yet fully dialed in. It is really obvious when you score vector lines in clear acrylic.
Slower speed/lower should help a bit, but dont think it’s fully avoidable yet.

You can try over extending the stop and start of the path into the waste area. (like a lowercase cursive “o”)


An example of what @bwente is talking about - this would be one open line that overlaps itself, with the ends extended. (It’s two colors so you can see the overlap of the open ends on the right.)

This kind of extension does work pretty well, I tested it on that grill rack hook. You want to start and stop the beam somewhere off of the shape.


Thanks for letting us know about this.

We’re seeing this as well, and the team is looking into it.

I’m going to close this topic – please post a new one if you have any other questions.
