Thanks for following up and for providing your feedback. I’m sorry for my delayed reply.
I’m looking into the issue where the app isn’t recognizing your material, and I’ll be in touch when I have more information.
Regarding the Glowforge scanning your material, when you click Print in the app, the printer head moves to the print area on the material to measure the height of the material. If it misses your material, don’t worry! The app will use the height you entered in each of the steps to focus the laser on your material.
Are you still finding that the camera seems slower than normal?
