Has anyone tried laser engraving glass yet I have seen engravings of pictures on the surface and inside almost like they engraved layer by layer. Is this possible with the Snapmaker?

I don’t think you can create holograms with a single laser. The effect should only be created inside the glass. Where two or more lasers cross it gets hot enough.
A single laser may be enough, but a machine costing 22000 dollars is needed.
