Button is yellow

Monday night my machine started making a weird sound and the button started flashing yellow mid cut so I turned it off thinking I would leave it for a bit and come back to it. I was only cutting a piece of 1/8 BB :woman_shrugging:t2:. Unfortunately I was only able to come back now and I turned it back on but the button on top is still yellow or orange. Any suggestions?

Check the white cable connection (with the machine off). Make sure it is clicked in tightly.

Oh no, I’m sorry to hear about the trouble @janel.

I extracted the logs from your Glowforge to investigate, and it looks like the orange button is appearing because 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 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 steps 4 and step 9.


Hi Jeramyh,

Here add the pics. Last week I had a lot of issues with the machine and this may sound completely insane but the gantry belt I think was dry rotted or something like that. It seemed almost the gantry was catching on it but took me a while to pinpoint it to that. My husband came home from work and said it smelled like burning rubber in the house. I ended up replacing the belt and now I’m trying to calibrate since I changed it.

Thank You
