Leaking smoke from front


I am cutting mdf right now but I notice that my room gets really smoky everytime I use glowforge Pro. I checked where the smoke came from and find out the smoke is leaking from the front bottom part where you can open the lid. It looks like it is closed correctly so I dont know why its happening. Could you please tell me a possible cause of this problem? Thank you.

Are you venting outside or into the filter?

Have you cleaned the fans and the smoke exhaust path?

There are a lot of openings that are supposed to draw air in when the exhaust system is acting properly, if smoke goes out rather than air in then the exhaust is not working properly. If you have a Glowforge Filter, then cutting MDF will kill a filter very quickly. If you are sending the exhaust outside then there is a lot of junk in the exhaust fan and outlet that needs cleaning.

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.

I’d like to make sure that the settings for your Glowforge Air Filter are correct. The knob on the Glowforge Air Filter controls the power to the fan. If the power is too high or too low, your filter will not work properly. I’d like to make sure it’s turned to the right setting.

  1. What setting is the knob on your Glowforge Air Filter turned to?
  2. If it’s currently on “New,” would you turn it to use the middle setting, halfway between “New” and “Full” and let us know if that eliminates the smoke and fumes while you print?

It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
