Error: an Error occurred on your glowforge

If anyone has advice on how to fix this error message:

“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 have done the following already:

  1. turned off my glowforge and turned it back on
  2. unplugged my glowforge and flushed my cache
  3. tried using a different web browser
  4. restarted my computer
  5. removed the printer head and reattached
  6. attempted printing glowforge provided art

I am getting this error any time I try to focus my printer. Any help would be greatly appreciated as I am getting very frustrated and very behind in work. Thanks!

Have you cleaned the windows on the bottom of the print head that make the autofocus work?


Help, my software is on broken iPad…I need new software to sell the glowforge or can I sell without software and new purchaser can download his own?

The Glowforge does not come with or use any software. It is controlled through a web browser.


I have done the same as you. If I start the app it will run for 30 seconds, show an “Unexpected error” and then restart. I am currently using Chrome but have tried other browsers.
