After Thanksgiving, I was running my running quite a bit for about 3 weeks. Roughly 3-4 hours per day during the week, and 8 hours a day on the weekend! It got quite the workout!
My wife really noticed the odor, and wasn’t too fond of the noise. My basement started smelling very strong, especially when I cut a lot of PG draftboard. I did some research here in the forums in an attempt to quiet things down, and also reduce the odor as much as possible. I thought I’d share some of what I’ve done, in case anyone else is in a similar situation. Pictures of my venting setup below.
But first, a little more about my setup. My glowforge s currently under a basement window, on the side of the basement where my furnace is. I am still holding out hope for a filter in the next 2-3 months, so I haven’t yet cut an additional vent into my house exterior. I am venting it out of one of those basement tilt windows. I have tall ceilings in the basement, so I had to use about 10ft of hose to get it out the window. There are also at least 2 90 degreeish turns- one right in the back of the unit, and one where it goes into the window.
At first, I just cobbled together two sections of the 8ft dryer vent hose, along with a “quick connect” attachment that I found at my local Menards (similar to a Home Depot if you’ve never heard of it). This seemed to work OK, but both noise and the odor were noticeable. I needed the quick connect, because I don’t leave it connected when I’m not using it- as the basement window is actually open. In order to keep the exhaust from blowing back in, I also bought a plastic window well and drilled it with a 4" hole saw. I ended up eventually taping it (masking tape to siding, and duct tape to concrete) so no air could get back in. This also has a nice side benefit of keeping the cold air out in the winter. I’ve left it open on days under 20 F and you can’t really even tell the window is open.
Anyway, I eventually changed out the 8ft flexible duct to an insulated plastic flexible duct. This was mainly because I wanted to reduce the noise of the unit. It did seem to reduce it, but not as much as I was hoping.
Today I added a booster fan. It was on sale from Amazon for $27 so I figured, why not. It claims to have a CFM of around 195, but I don’t think it’s really that strong. I put it near the top of the window, to help boost it past the second 90 degree bend.
Out of anything I’ve done, adding the booster fan seems to have made the best improvement for the odor. At this point, I feel like I’ve taken it about as far as I can go. Hopefully I can live with this setup for a little longer until the air filter is available.
Here are links to what I am using, in case anyone else is interested.
