Rendering times very long

I’ve been using my GF for 2 years… the rendering times are remarkably slow today. I’ve never seen it so slow.
I don’t have a wi-fi problem.
I tried using Edge and Chrome, same results.
The design is incredibly simple.

Hi @halgrenj

What do you mean by “rendering times”?
I just opened… was pretty snappy.
Opened an existing design… normal speed.
Uploaded a new design… seemed fine.

Which thing was slow for you?

Given you tried multiple browsers, it does sound like it could be your Wifi.
You might want to try a speed test: speed test - Google Search at least from your computer/phone (while on Wifi)

Good luck!

No, I mean “rendering speeds”.
When the app sits telling me it’s ‘rendering’ for 30 minutes it’s not on my end.
Now it just told me it had a problem uploading my design and come back later.

Not having the same issue. Try clearing your cache or opening a different file.

Have you tried refreshing your browser? Maybe there are updates taking effect.

Every time I get that error there is something funky in my design.


Do you mean you’re seeing this screen for 30m?

Do you see that when you open an existing design?

If so, I suspect it has something to do with your internet connection (to your computer) and/or your browser. Trying clearing your cache, try different browsers, try running a speed test.


Hello, @halgrenj I am very sorry you are running into this problem on your Glowforge printer. After carefully reviewing the logs of your Glowforge printer it looks like there may be an issue with a steady Wi-Fi connection.

The best way to rule out an issue with the Wi-Fi is by connecting to a temporary Hotspot. I will leave you with some steps below-

Your Glowforge needs internet access. However, it does not need to be connected to the same network as the computer, phone, or tablet you are using to print.

For example, you can create a hotspot on your cell phone and use that network to connect your Glowforge to Wi-Fi. This is a good way to rule out Wi-Fi 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 from your 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

Hi @halgrenj. It’s been a while since Jeremy’s response, and I wanted to check in to see if you’re still running into any issues with the Glowforge app as it tries to render designs. I’ll leave this thread open for another 2 days, and feel free to let us know if this has been resolved, or if you need any further help.
