Question. Recently got myself a brand new hose (and insulated one!) and I had a ton of excess hose so I cut it in half (yay, back up hose) but I’ve recently learned it’s still about 2 feet too long for the fan to be pushing stuff out and I plan on fixing that today by cutting it down further- someday I’ll have an in-line fan.
Anyways, question, I know a long hose is bad but can you have a hose too short?
I’m upgrading the spot where I keep my GF and it’s right there at the window, excess hose kind just gets all smooshed up around the back before going out the thing. I have one of these things in my window now where the hose connects to go outside-
And a thing on the outside of it that has shutters to keep stuff from being blown back in. When not in use I always remove the whole setup from the window cause we don’t trust the people coming and going from the place nextdoor. XD
Here’s what the rest of my current setup looks like at the moment. When in use (aka, back into the window) I tape all the gaps up. The blanket is because it’s winter time here and a lot of cold escapes through the glass.
Also despite looks my hose is fully connected to both machine and window thingy- you’re just seeing the bit around the insulation that’s around it.
Right now, my GF is on a table that is literally ankle height and that’s fine but I’d really like to move it to something higher. I have a dresser that is the perfect size for my GF (like, right on the nose for measurements) but comes up just above the window opening. Hence why I’m thinking about how much I can cut down the hose.
You might have missed the comment I added about the right-angle turn.
The hose can have rounded corners in the hose, like the first image below, but a sharp angle like (what appears to be) that extension panel is not a good idea.
As to hose length, a few feet vs two feet will make no difference.
I would not recommend using without a hose, I just meant the machine will still operate fine.
As state above, operating without the hose is not advised. As for the telescope extension- You can use that but you would also have to get aluminum tape to seal up the gaps. Stock it does not seal at all as this is designed for a dryer.
As 90 degree bends, the extender has two half moon bends on each end. Glowforge recommends no more then two 90s in a run. But depending on the length and if you have a booster you can run more. If you do that, Glowforge will not provide support unless you reduce the amount of bends.
I used that same exact thing for about 4 months (with tape). Then switch to an insulated hose to reduce the noise. My setup has 3 90 degree bends also has a booster down range- total run is about 21ft.
My setup might be a challenge to beat for shortest hose length. Probably not longer than 24" at most. I’ve been running it like this for over 2 1/2 years now without any problems.
Right now mine is waaaay too long, it’s in a big loop behind the machine and I knew I had to cut it down (my husband’s logic was longer hose better bless his heart) but the more I thought about it the more I was like I bet a short one would actually be the way to go, much less chance of me smashing it against the wall and kinking it and less distance for the air crud to travel.
Just the one bend. I used a piece of hose from my shop dust collector and connected that to a dryer vent installed in a piece of plywood which I close the window on. You can see the tape where I seal the window to plywood crack. I remove the whole thing when I’m not using the GF.
