Hi @sarjanlong, I am so sorry you are having issues cutting through Proofgrade Material! Thank you for taking the time to do some initial troubleshooting. Can I have you check a few more things as well?
Please send photos of all your cleaned optical components, with special attention to any damage you might find:
- Both windows
- The printer head window, on the left hand side of the printer head
- The laser window on the inside left of the Glowforge
- The printer head window, on the left hand side of the printer head
- The printer head lens
- Both sides of the lens, top and bottom
- Both sides of the lens, top and bottom
- The 45 degree mirror inside the printer head
- The bottom of the printer head
Once we have those pictures, we’ll follow up with next steps.
Thanks!
