In the scenario @jbmanning5 mentioned:
The Glowforge would focus to 0.375, and the 0.5 material height would be ignored. You can change it anytime up until you press the print button.
However, if the autofocuser fails because the material is too high, unfortunately the print will still be blocked from starting.
If you’re interested, there are more details on this old post from 2018.
