I’m sorry the Proofgrade material wasn’t being detected as expected.
I extracted the logs to look into the issue, and it looks like on prints where Proofgrade wasn’t recognized, there was a very bright light shining into your Glowforge during that time. On prints where the light level was lower, the logs showed that the Glowforge recognized the Proofgrade. If the app has trouble recognizing your material again, would you try reducing the direct light overhead and see if that helps?
The good news is the logs indicate that Proofgrade is being correctly detected most of the time.
If this happens again, you can always select your material – here’s how:
Click “Unknown” on the left hand side of the Workspace
Type the name of the Proofgrade material in the search bar
Select the correct Proofgrade material
I’m going to close this thread - if the problem reoccurs, go ahead and post a new topic. Thanks for letting us know about this!
