Fantastic laser cutter that is easy to use.
I've used a number of laser cutters in the past, but the Glowforge is by far the easiest to set up and use. Unlike other machines which require installing obscure and barely-supported drivers, the Glowforge web app makes it incredibly easy to import and lay out graphics, modify settings, and get great results. From the time I plugged in the machine until I had completed my first print was maybe 15 minutes.
I only have a couple of things on my wish list for this already fantastic machine. The web app has a lot of capabilities that are not always easy to discover, such as selecting, resizing, and moving individual layers of your design. A bit more work on making this UI more intuitive would help a lot. Second, my machine has problems with the lid camera focus which are not apparently easy to address (there's no way to change the focus of the built-in camera). And finally, I purchased the compact filter not realizing that it would be incredibly loud (like a very loud vacuum cleaner) to run -- had I know this up front I might have reconsidered my filtering options.
But all this said, the product is on the whole incredibly well designed, polished, and a great purchase. I am very happy to be a Glowforge owner.
