I’ve been having some of the smoke issues others have described, but I’ve only had my glowforge a little over two weeks and used it pretty lightly, especially with wood. Right from the beginning I had exhaust issues, so it’s not build up or hose obstructions (I checked anyway, just to be sure) then I ran a light cut with the exhaust hose off and noticed that the fan directly at the exhaust port did not appear to be moving.
Unfortunately we’ve found your unit has a problem we can’t fix remotely. I suggest we proceed with a warranty replacement and I’ll reach out via email to sort out the details.
