Make sure your Glowforge fan settings are correct
The Compact Filter setting changes the speed of fans in your Glowforge. If this setting isn’t correct, the air will not not flow properly.
Here’s how to change the setting:
Sign in at https://app.glowforge.com
Click the gear icon, and then adjust the setting for “Compact Filter attached”
If you are using a Compact Filter, it should be switched to the right and show teal
If you are venting to the outdoors, it should be switched to the left and show gray
