Want to be clear, since other lasers don’t allow you to automatically perform a double sided cut, it is not a Glowforge limitation. Apples and Oranges. Now there are of course limits in how the capabilty can be used.
Separate subject… Folks have argued here, at length, about the benefits and limitations with respect to a Glowforge home or set 0,0. There has been discussion with one of the operators about testing it on a pre-release unit. Suggest you start with these topics. Good luck because it is very long and all over the place. Sorry I can’t give you a direct answer that won’t devolve into the same back and forth.
