Dead glowforge

Hi everybody!

I was working with my glowforge this morning and then suddenly it was totaly dead.

Anyone have amy ideas what could be wrong?



I have the glowforge Pro model

Depends what you mean by “totally dead.”

If it no longer turns on - no LEDs, no start-up process, etc., then check the power outlet is still working. Try a different cable if possible (it’s a standard computer power supply cable.)

If none of that helps, then it’s likely the power supply is dead.


I wont start , just black, i only hear a ”click” sound when i turn the power on/off

Did you check the breaker in the machine ?

Hmmm dont realt know What the breaker is?

Now i know … its the round thing over the powerbutton?

The round thing over the power button is a safety interlock for places that require the machine stop if someone enters the room. the staple part in the middle pulls out.
This is what is looks like removed.

The pin is in … we think its the powersupply

…soooo… is our solution to send the Machine back to the glowforge company?

We realy need the machine everyday and we live in sweden …

I’m so sorry to hear that you’re running into trouble. I’ve extracted the log files from your Glowforge to review your most recent prints.

Your Glowforge should be plugged directly into a grounded wall outlet that meets local building codes. If you haven’t already, please do the following:

  1. Unplug your Glowforge from the wall
  2. Plug another device directly into the same outlet and see if it works
  3. If the device does not work, have an electrician investigate. It may be a blown fuse, a broken outlet, or something else
  4. If the outlet works, unplug the other end of the cord from the Glowforge unit itself
  5. Inspect both ends of the power cord; if you notice any damage, try another power cord
  6. Plug in the end of the power cord that goes to the Glowforge, making sure it is inserted all the way in
  7. Plug the other end of the power cord into the outlet, making sure it is inserted all the way in
  8. If your Glowforge still won’t power on, try another outlet

Also, I’d like to review some images from inside of your Glowforge.

Assuming you’re using a smartphone, try these tips for great photos:

  • Use flash
  • Zoom in using the digital zoom
  • Hold the camera/phone far enough back to get good focus.

Here are the photos:

Motor on the laser arm (and surrounding):

Inside, left of machine:

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:

Left side of front door:

Once you can review the outlet your Glowforge is connected to, and send over the photos for us to review, we’ll send over the next best steps.

There is no “breaker” on the machine. The interlock does not affect power. It completely halts operation of the machine but it remains powered, and it has to be power cycled to reset.

Sorry for the late reply, now we have had an electrician that looked at our Machine , there is power inside the Machine when the electrician looked with a multimeter, we have tried 3 different cables så that Can’t be the error,

We dont hear amy sound of amy kind and the Machine is ”dead”

I might be in error, but that interlock would seem be the last chance to stop everything so no power reached the machine.
Btw is the power there 220v? Is there a way to switch it each way 110-220?

Thank you for the photos you’ve sent so far. I extracted the logs from your Glowforge to investigate, and it looks like your unit was able to connect to our servers today, but the 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 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 this board.
  10. Turn your Glowforge back on.
  11. Send us the photos you took in step 4 and step 9.

We’ll review the images and follow up with next steps.

So here ate the photos you asked for… hope we can come to a solution soon.

Have a nice day

Thank you for the photos. The pins and board both look like they’re in good condition. As a next step, will you please let me know if the same issue persists after you reconnect the ribbon cable to the print head and start your unit back up?

Its still dead
