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 laser head. When your laser head is sitting properly, the fan will push smoke away from the print area and give you cleaner prints.
When the head is not seated properly, however, the attached air assist fan will not be able to spin up to full speed. Should your laser head not be making contact, you’ll see an “Air assist alert” in the app when you print.
If you run into this alert, here’s how to re-seat your printer head. Before you begin,
turn off your Glowforge and unplug it.
If you haven't already, try cleaning your air assist fan. Sometimes an Air Assist alert is just a sign that it's time to give it a good clean! Take a photo of the air assist fan in case you need to send it to support later.
If that doesn't work, or you've already cleaned it, continue to step 2.
Remove the Printer Head
Holding only the finished black surfaces, grasp the printer head as shown. Pull gently up and back to disengage the magnets and remove the head.
Clean the contact points
Wipe the 4 gold pins next to the lens on the bottom of the printer head, as well as the 4 gold contacts on the carriage plate. Take a photo of these pins in case you need to send it to support later.
- Look at the back of the print head, and check the other side of 4 gold pin connector for damage or anything unusual. Take a photo of the back of the print head, similar to this example, in case you need to send it to support later
Reconnecting the printer head
Re-lower the head over the metal plate so that it rests next to the two round posts. Push it gently away from you – you’ll feel a “click” as magnets pull the printer head until it sits snugly atop the metal plate.
Restart your Glowforge
Plug in your Glowforge, and turn it back on to run a test print.
If you are still running into trouble after cleaning and trying these steps, please contact Glowforge Support, include the photos you took during steps 1, 3 & 4 and let us know what you've tried so far.
