Don’t lose your head

Monitoring improperly seated printer head

Your Glowforge has a small but powerful fan directed right where the laser contacts the material, called the Air Assist Fan. It’s under the laser arm, behind the printer head. When your printer head is sitting properly, the fan will push smoke away from the print area and give you cleaner prints.

When the printer head is not seated properly, however, the attached air assist fan will not be able to spin up to full speed. We’ve seen a number of customers who are suffering from this, so we added a helpful alert when this happens. Should your printer head not be making contact, you’ll see an “Air assist alert” in the app when you print.

If you run into this alert, follow the instructions here to reseat your printer head. Should that not solve the problem, contact us at and we’ll get you squared away.
