I’ve been experiencing a specific issue since the day I received my Glowforge Pro a few months ago. I spent 50% of my time actually troubleshooting rather than cutting and clapping to myself. Yesterday I narrowed the problem down significantly, and I believe I received a defective unit (or at least my focus lens is scratched.
I’m experiencing an issue with cutting all the way through, but only on the right half of the bed (except the top couple inches of the right half). Even proofgrade materials won’t cut all the way through. I ensured the bed is sitting perfectly level and thoroughly cleaned under it. I’m almost certain it’s related to the lens focus, because every time I try to manually set the focus anywhere in that area, it returns this error:
(ignore the bottom part of screenshot. It always attaches itself to every screenshot and I don’t feel like editing it out).
Attempting to manually set the focus elsewhere on the bed works just fine.
For the record, neither of the red outline parts in the above picture cut all the way through. Everything else cut just fine.
Now here’s the thing… If I were to clean all the lens right now, I would immediately stop receiving the above error when doing a manual focus and it would actually cut all the way through everywhere on the bed, but only for a few cuts (around 30 minutes of cutting). Then it would go back to not cutting all the way through in that area of the bed again and returning the same error.
Below are some pics of the lens. I’m especially concerned about one of the lens on the underside of the head (is this the focus lens?), which looks either scratched or has specs of dust which appear to be on the underside of the lens. It has looked like this since the day I installed it. I didn’t think much of it initially, but now I’m starting to think it may be the culprit.
