I’m sorry for the trouble when trying to run a calibration on your Glowforge, and for the confusion caused by the error message you received. I extracted the logs from your unit, and I what I found suggests that this isn’t related to your unit’s Wi-Fi connection. It looks like your Glowforge may be having intermittent trouble communicating with the print head.
There are two key connections I’d like you to check for me. Could you please do the following?
- Turn off your Glowforge.
- 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.
- There is a small tab in the center of the wire ribbon. Push down fully on the tab to release it, and gently pull the wire ribbon plug from the printer head.
- Take a clear photo of the gold pins inside the printer head where you just unplugged the wire ribbon. It should look like this.
- Pick up the printer head and wire ribbon. Make sure the tab on the wire ribbon is facing up. Slide the ribbon back into the head until it clicks.
- As shown, lower the printer head over the metal plate so that it rests next to the two round posts. Then 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.
- Pull the laser arm all the way forward.
- Reach over the laser arm, and to the left of the inside of the unit and you’ll see this circuit board:
- Take a photo of the circuit board. If the cable I’ve indicated above with the red arrow appears to be loose, please reconnect it and try printing again. This cable should ‘click’ back into place.
- Turn your Glowforge back on.
- Send us the photos you took in step 4 and step 9.
Please let us know what you find. We’ll review the photos you share and then follow up with next steps.
