We are having a serious problem with the air quality after using the Glowforge. We have written to the company and on every platform we could. We are using draftboard and filtering out of our window. We previously were using the compact filter but when that wasn’t working we switched to outdoors.
Basically what is happening is that after a few minutes of the laser being on, the entire room smells almost like burnt wood. It is giving me a headache and makes it difficult to breathe. The smell lingers for days and into our home where our two small children also reside. We have checked the connection and made sure to patch up any space air could be escaping. We have cleaned the machine and the fan as per recommendations from glowforge.
Is this due to the material we are using? Has anyone had this problem? I feel like I’m seeing so many people use the machine without hassle. Wondering if it is maybe just my machine? I’m nervous about harmful chemicals being emitted into my home!
It sounds like you have pinholes in the vent tube going to your vent area and you may not have sealed the exit as well as you thought. If you are getting that much smoke and smell into your work area you have a leak. There is a lot of reference material on this forum for dealing with the leaks, but the first thing that is usually recommended is that you replace the vent hose that comes with the GF with a better quality hose.
I run an air filter during and after I use the GF to clear out those smells and they rarely last longer than a few hours.
Make sure you have turned off the “Compact Filter attached” setting:
When that setting is enabled it turns off the fan that’s built in to the Glowforge (to prevent interfering with the filter’s fan). When you don’t have the filter attached you want the built-in fan to be running in order to push the air outside.
I’m so sorry to hear that you’re running into this snag.
When your Glowforge and Compact Filter are properly set up, you may have some harmless odor during printing which will rapidly dissipate. You may also smell something when you open the Glowforge lid after a print is complete. This is not harmful.
However, if you notice a strong, unpleasant or irritating odor when printing, or see smoke, shut off your Glowforge unit immediately. Smoke and fumes could be entering the room in excessive concentrations.
There will be a fix for this.
You should not smell anything, except sometimes when some lingering scent when door is open and piece removed allowing for some trapped smoke to dissipate.
Normal cutting engrave and score operations should remain odor free if all is in order.
It took me a while, but after sealing all of my long exhaust run I have zero smell during even 2 hour engraves.
Has it always been this way? If so there is a/are leak(s) in the exhaust setup if the exhaust fan is running.
The fan guard for the exhaust (picture #7 in the reply from support) will eventually get blocked by debris, so check that the grill isn’t clogged.
@dr.krawetz, it isn’t air tight, but the exhaust fan moves more CFM than the intake fan, so there is a negative pressure inside the machine, so very crack in the case should be sucking air in…
Over 3 years of use and there is zero smell during operation. Only a whiff when opening the lid after an operation.
