VENTING -- I made a critical mistake

I used to work in HVAC, and used These all the time, ( Backdraft Shutter Damper Connector Duct) and they are wonderful, but I recently discovered that the Glowforge’s smoke, has a Sticky quality to it, and GLUES IT CLOSED… so you need to CLEAN THEM once a month, or use some other method to keep humidity / water out of your GF.

they are a lot easier to deal with since its ‘automatic’ but you also gotta keep em clean.

and the only caveat to those is make sure it’s not one with a screen inside of it. i wasn’t thinking when i installed the one i bought that had a screen at first and it clogged up in a week or two. just pulled it out and now it works fine.

Never have I ever . . .

thought smoke would be ‘sticky’ but in retrospect plywood has a lot of resin in it, and other bonding agents, when they are cut / burned / etc… that resin would vaporize.

makes sense.

acrylic too.

MDF is the worst here, I think. Hence why it just straight up houses filters.

I’ve used the same vent since I setup my GF. Never had a problem with it.
