I’m so sorry to hear about the trouble with the Compact Filter. 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://glowforge.com/support/topic/troubleshooting/print#excessive-smoke-or-fumes-during-print
Would you mind posting 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 post it on this thread.
Thank you for taking the time to post this photo. We will take a look and follow up with your next steps.
