I’m sorry to hear you hit a sang with your Glowforge.
I extracted logs from your Glowforge it looks like you were trying to print with you the crumb tray.
You can print on objects up to 2" thick by removing the crumb tray. However, your Glowforge can’t focus too far down, so you may need to put something laser-compatible underneath your material to lift it up. Raise it until the top surface of your material is between 1.5" and 2" (50 mm) high, measured from the metal plate on the bottom.
