I am a school librarian and use our Glowforge in the Makerspace. We have been using it many times this year to cut both wood and acrylic with no issues at all. However, today I was firing up a job on some draft wood and smoke started billowing out all over. By all over I mean the from and top of the machine. I have it vented to the Glowforge filter and it was on and turned all the way up. It appears as though the air is “sitting” and not being sucked out the back. I check the vent and there are no obstructions and the hose is a short run with no bends in it.
Any ideas of what it could be? I can’t have smoke leaking out in a school setting.
