Print Cancelled Alarm


I just received my GF a week ago. I followed the step by step instructions carefully. It sits on a table about 10 feet from my WiFi router. Then, I attempted to make my first print. This hasn’t happened yet.
Looking at the app, it toggles back and forth from “centering” to “off line”. When in centering, it moves under the camera for about 30 seconds then to the left for about 30 more. After about 30 minutes the print button is active. As soon as I hit it, I get the print cancelled alarm. This has happened twice, the day I got it and 2 days later when I tried it again. Any help would be appreciated. Thanks.


There’s a list of troubleshooting steps here that might help to narrow down the first part of the problem:

When you say “print cancelled alarm,” what exactly is happening? Is there an error message?


I’m pretty sure that the problem is signal related. Although the GF is only about 10 feet away from my WiFi router AND in a direct line of sight (no walls), the GF still goes off line every couple of minutes. I’ve been through the WiFi troubleshooting guide several times.


Were you able to print using a cell phone wi-fi hotspot?

Try a different 2.4 GHz channel.

I’m sorry to hear you hit a snag. I extracted the logs from your Glowforge to investigate your report, and it looks like your unit is having trouble maintaining a stable connection to our servers. Connections are occurring multiple times within a ten minute period. This can definitely lead to calibration and printing trouble.

Though network-specific Wi-Fi challenges may occur for a number of different reasons, I have a few suggestions that may help:

  • Since Glowforge only uses the 2.4GHz frequency, a connection will be harder to establish and maintain on a crowded 2.4GHz network. Other devices using 2.4GHz, like cordless phones and microwaves, can cause interference and an unstable connection. You can consult your router settings to check the performance and traffic on your 2.4GHz network.
  • In your network settings, check the channel you’re using for the 2.4GHz band, as @Tom_A suggests. Trying a different channel may provide a more consistent connectio

If you’re still having trouble, there’s a test you can try that will help us narrow down the problem. If possible, could you please create a Wi-Fi hotspot with a cell phone and use that network to connect your Glowforge to Wi-Fi? This is a good way to rule out signal interference, since you can set your phone right on top of your Glowforge!

You can find instructions online to help you create a Wi-Fi hotspot using a cell phone. Make sure that you set it up to be a 2.4 GHz hotspot, since that is the frequency your Glowforge uses.

Once the Wi-Fi hotspot is broadcasting, you can connect to it by following these steps:

  1. Turn on your Glowforge.
  2. Wait 30 seconds. Then hold down the button for ten seconds until it glows teal.
  3. Navigate to and follow the instructions on-screen. When prompted to connect your Glowforge to Wi-Fi, choose the hotspot you created.
  4. Once Wi-Fi setup is complete, go to and try a few prints.

Let us know how it goes.
