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.
We’ve created a troubleshooting guide with illustrations. You can see it here: https://support.glowforge.com/hc/en-us/articles/360034142593-Excessive-Smoke-or-Fumes-During-Print
I’d like to take a look at an image of your filter cartridge. Would you mind sending over a photo of the top of the filter cartridge?
Turn off and unplug your Compact Filter
The power switch is located on the back, next to the cord. Turn it off first, then unplug it from the wall.
Open Compact Filter
There are four latches holding the top of the Compact Filter in place. Lift the bottom of all four latches to release them.
Take a picture
Without removing it, take a picture of the top of the cartridge seated in the Compact Filter and send it in to us.
Once we can review this image, we’ll send over the next best steps!
