This area is for known issues with the Laser Cutter and how to solve them.
Problem: Circles being cut on the laser are not round but rather a slight oval shape. It is usually easier to spot on smaller circles.
Solution: Make sure the lens and mirror have been cleaned properly and that the lens has been fastened. If this doesn't solve the problem the cause is most likely buildup of debris on the track the lens sits on. If there is any resistance when sliding the lens down the track there is most likely a buildup. To remove the buildup use an angled awl together with a wet wipe wrapped over it and slide it up and down the track. you can also use cotton-tip buds but will most likely need something sharp to get all the way to the back. Rinse and repeat until the lens slides in and out smoothly
