Fired up my Glowforge yesterday, and had an issue where it reported as calibrating for over an hour. Powered down, manually moved gantry to “home”, and eventually got it to wake up and cut a job.
Today: same problem. Except that I can’t get it to “wake” at all. Help!?
Is it doing anything? Hunting around? Light flashing white at all?
Have you cleaned the lens for the lid camera?
How’s your WiFi?
Any material in the bed with holes?
Doing nothing…no gantry movement, no flashing light, nada. App reports “calibrating”. Power cycling doesn’t change anything.
Have cleaned all lenses, mirror, and made sure nothing was impinging on gantry movement.
Wifi is awesome and solid for everything else in my house, although I’m betting that my network is blocking something now that I think to check…
Damnit. Yes. Looks like Glowforge is using https://www.getanywhere.io as an IoT middleman. My Pi-Hole installation was catching it. Whitelisted, and it looks like it’s working again.
Sorry, all. If anyone else is running a network firewall/ad blocker, they may hit this issue.
Well. Hurm.
It was working, after I whitelisted the above URL, but now it looks like I’m back in never ending calibration. Don’t see anything being blocked on the network front, am getting no movement or response again.
Glowforge support: can you take a look on your end and see if you see anything odd?
Thanks for following up. I’m sorry to hear you’re still having trouble. I took a look at the logs from your Glowforge to investigate the problem and it looks like the particular connection returning an error is the attempt by your Glowforge to download necessary calibration information from storage.googleapis.com on port 443. getanywhere.io is not used by our software and should not be a required connection at any time to use your Glowforge, but it may help to look into your current network rules on accounts.google.com and *.googleapis.com. Your Glowforge communicates with these domains on ports 80 and 443, for http and https traffic, as well as websockets.
Could you please let me know if this helps?
That looks like it fixed it! Thanks for the tips and the URLs…whitelisting those did the trick. I don’t know why I was seeing getanywhere in concert with the Glowforge if y’all aren’t using that service. Coincidence with some other networked thing in my house…goodness knows there’s enough of them.
I’m glad to hear that! Thanks for letting us know about this, and again I’m sorry for the inconvenience. If you run into any other trouble, please open a new thread or let us know at support@glowforge.com.
