Error - Please refresh browser

Hello,

Hoping for some advice. I printed a ton yesterday, and then started receiving the error that I needed to refresh browser or restart my machine.

I figured my machine was hot from using it all day so, I cleaned it well and let it cool down for awhile. Tried Printing all night last night and today and still getting the same error.

I went home on lunch and was able to print, but after the first print, once again getting the same error.

I have cleared out the cache. I have tried different browsers.

Any suggestions on what the problem might be?

Hello! I’m sorry to hear about the trouble you are experiencing. 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 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.
  12. Once you have completed all the steps, could you run a test print and let us know how it goes?

Thank you so much for troubleshooting with us. Once I have your photos I will be able to review for any next steps.

I have been working on it and it seems to
Print at random. It will print, then it will give me the same error multiple times.

Then all over again. I will change browsers, clear cache and cookies.

I tried printing after the steps and it gave me the same error. I cleared my browser, signed in and out, and it printed. This is the same
Thing it’s been doing in the last few hours.

Hello,

I never heard from anyone today. Any advice?

I am still have the same trouble with the error.

Hello! @jdbrentham My apologies for the delay. Thank you for working with my colleague Danielle. From what I can make out from the pictures it looks like one of pins may be bent.

If the pin is bent you can try gently bending them back straight with a pair of pilers. Let me know how it goes :slight_smile:
