I am getting this message when I am trying to focus my glowforge:
" Error
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."

I noticed it shoots the red laser beam twice before going back “home”. Normally it only does it once

I already did this, even restarted the computer. Anybody else experiencing this problem? And yes, the lenses are clean and so is everything else

After re-starting the glowfoge 4 times it started working again. Strange!!!

Any chance there was holes in your material, or was it particularly dark, or reflective? Sometimes it can’t decide if it’s getting a good reading so it’ll try again, and then pop the error.

It had white masking tape, eventho the material had holes in other areas, the area where the red laser beam was being shot at was completely flat and clear

Hi @TheForger - I’m sorry to hear you were having trouble with trying to focus, and glad to hear it’s since started working for you.

I’m going to go ahead and close this topic since the issue has since been resolved, but I wanted to provide some steps you could try in case this should happen again in the future.

Please try the following should your issue come back. If you still have trouble afterwards please let us know!

  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.
