Set Focus Error message

When I use set focus sometimes it says an error has occurred. If I keep trying it in different spots on the board it will eventually work. Not sure if there is a particular reason it’s not working in relation to where I select it to set focus on the board or not. Thanks.

Glare on the material, or holes from previous cuts could do that. You’ve opened a support ticket by posting here, so they’ll be along soon – they might be able to tell more from your logs. :slight_smile:

Hello @ihavenoclue5,

Thank you for reaching out to us. I’m sorry to hear you’ve been having some trouble using the Set Focus on your Glowforge.

I extracted the logs from your Glowforge to investigate, and it looks like your Glowforge is having trouble communicating with the 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 you feel it click securely back into place.
  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, please use flash. 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. Try a small test print using Set Focus. Let us know if you receive an error.
  12. Send us the photos you took in step 4 and step 9.

Once we have the photos and the results of your test print, we’ll review everything and follow up with next steps. Please let us know if you have any questions. Thank you!

Thanks it seems as though it was the windows on the bottom of the print head!

Fantastic! I appreciate you double checking the instructions my colleague Morgan provided, and for cleaning the bottom of the Printer Head. I’m so glad to hear that everything appears to be working correctly. I’ll now close this thread, but please don’t hesitate to reach out to us in the future if you run into any more trouble. We’re here to help :slight_smile:
