Set focus problem

Anybody experiencing issues with Set Focus? I just finished some engravings and was gonna start another set and it doesnt want to set focus

Red laser is shooting twice to set thickness (normally only shoots once)

An error occurred on your Glowforge. Please refresh your browser before printing. It may also help to turn your Glowforge off and then on again."

Got fixed by itself after trying about 10 times

I’m so sorry to hear that you’re running into trouble, but I’m glad to hear that it looks to be working once again.

I’ve extracted the log files from your Glowforge to review your most recent prints, and I noticed that you’re unit is experiencing trouble measuring the height of the material, due to a communication error with your Printer Head.

There are two key connections I’d like you to check for me.

Could you please do the following?

  1. Turn off your Glowforge.
  2. 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.
  3. 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.
  4. Take a clear photo of the gold pins inside the printer head where you just unplugged the wire ribbon. It should look like this.
  5. 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.
  6. 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.
  7. Pull the laser arm all the way forward.
  8. Reach over the laser arm, and to the left of the inside of the unit and you’ll see this circuit board:
  9. 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.
  10. Turn your Glowforge back on.
  11. Send us the photos you took in step 4 and step 9.

Once we can review these images, we’ll send over any additional steps.

It’s been a little while since I’ve seen any replies on this thread so I’m going to go ahead and close it. If you need any additional help with this please either start a new thread or email
