Hello @evelina, Thank you for reaching out to us. While the issue might be settings related, based on the looks of the circles in your photo it does look as though there may be a mechanical issue at play here. In addition to checking your settings, I’d like to have you check a few areas inside your unit as well, just in case.
To start, I’d like to have you check the tension of your belts. When pressing lightly on one side of the belt, the other side should not move.
(You should see an animated image above)
If a belt is loose, you can follow this link for instructions to adjust the tension of the carriage plate belt or here to adjust the tension of the side belt.
If the belt tensions are good, next I’d like to get a few photos from you:
First, power off your Glowforge and remove the crumb tray.

Finally, check the wheels on your carriage plate for any cracks or damage following these steps.
- Turn off your Glowforge
- Remove the carriage plate from the laser arm
- Closely inspect the carriage plate wheels from the top for any cracks or other damage
- Closely inspect the sides of the wheels for any cracks or other damage
- If you notice anything damaged or out of place, please take a photo and attach it to your reply.
Please let us know what you find. Thank you!
