I find that the closer focus the less flaking of the glass from the mirror fracturing.. Basically zero clean up.. I have tested defocusing away as well and only close.. 2-3mm will work.. Not sure for the reason beyond how the beam is interacting with the glass.. If you focus at 6mm you will have scaling and little shards that must be cleaned.

Chris, great video, thank you. When engraving glass what air pressure do you use, high or low? Context - do you high for cooling?
Still waiting for my Bolt. Do you know what setting can be done to achieve this with Thunder Bolt and Rotoboss? Thank you in advance.
Cool. What is the benefit for 3mm focus vs. 6mm?
