Hello, I post it here in Lightburn as I have no replies in reddit and fb pages. I have a problem with my Sculpfun S9 laser. The laser dot seems to be thicker than it was originally. I wanted to clean my laser head but the protective lens (orange lens) is stuck, I assume it is because from the resin of the wood from burning. Any tips on how to pull it out? Here is a sample of cuts weeks before and now.
EDIT: I have unscrewed the screws before attempting to remove the lens.
