We have been using our Glowforge Pro for a few weeks now. We haven’t exactly got into what I would consider a “production” mode, but I would say we have put about 30 hours or so on the machine. What concerns me is I am starting to notice a buildup of residue on the inside of the lid. This residue is most likely all over the interior too. Nothing what I would consider crazy, it seems to be mostly some minor fogging on the glass. We vent to the outside (we use a dryer vent type setup), and when the GF isn’t in use we secure it from outside air, so nothing can get in. Because of this I feel like I can safely assume it is venting properly.
Is this happening to anyone else? Should I be worried? Do I need to regularly clean the laser lens with special cloth?
