Thanks for posting photos of your print that failed to cut through, as well as the screenshot of your setup where Proofgrade material wasn’t recognized.
I’ve extracted the logs from your 20 most recent prints, and I’m seeing a total of four prints where Proofgrade material was used. It looks like the QR code was recognized on three out of four attempts. In the print in your screenshot, it appears the Glowforge app mistakenly tried to read a previously-cut design, rather than your QR code.
It’s possible for the QR code to look blurry, but still be interpreted successfully by the app. Would you let me know if the app’s failures to recognize Proofgrade material increase in frequency?
Regarding your trouble cutting through Proofgrade material using default settings, could you please turn off your Glowforge and check the following:
Once all these things have been checked, please perform the following test print.
Print the Gift of Good Measure on Proofgrade material, using Proofgrade settings.
When the print finishes, leave the lid closed and wait until the fans stop and the picture updates.
Check the completed print:
- If the Gift of Good Measure fails to cut through, take a photo of the front and back of the print and attach these photos to your reply.
- If the Gift of Good Measure cuts successfully, please try another print of the design you experienced the issue with, and let us know the results.
