    The software and user interface on a galvo (at least the ones I've used) are nowhere near as user friendly as with a gantry type machine.

    Try putting the glass in the fridge before you engrave them. I find that cold glass is less likely to have the little splinters in the engraving and have more of a nice frosted look.

    Or the worst. :)
    All the expense of a galvo. And if it can cut, only the speed of a gantry. And probably the software of a galvo but worse because it has to tile it as well.
