Stuck on focusing laser head not making any clicking noise when turned on

First time I have ever had this issue.

Rebooted computer and now focus and printer head is working. Does anyone know why and if this would have fixed the issue? Thanks

If the laser loses its WiFi signal it can’t complete the focusing cycle. Likely rebooting allowed it to reconnect with your router.


Hi @ihavenoclue5. I’m sorry to hear that you ran into some trouble with your Glowforge failing while it was focusing. I saw you mentioned that it appears to have been resolved after rebooting your computer. Just in case you are continuing to run into the issue, I have some troubleshooting steps below to help.

I extracted the logs from your Glowforge to investigate the problem, and it seems like your unit was running into trouble during the calibration step in which the lens focuses inside the printer head (you may hear this when it’s happening - there’s an audible “ticking” sound as the lens moves up and down in the head). There are a few different reasons this error may be occurring. Could you please check a few things for me to help narrow it down?

  1. Check the printer head lens by following steps 1-5 from these instructions: If you see anything unusual such as damage to the lens or debris in the printer head, please take a photo of it and attach it to your reply

  2. If you are using magnets to secure material to the crumb tray of your Glowforge, please remove or reposition them and try again. Magnets placed close to the printer head may cause trouble during calibration

  3. Check the connection of the printer head to the white ribbon cable in the printer arm. Turn off your Glowforge, unplug the head, and plug it back in. Note whether the cable plugs back in securely, and whether you feel it “click” into place

Let us know how it goes! Thank you.
