Ironically, my GF isn’t in another room. It’s in the same room as my computer. It’s just when I’m cutting several things, I may send a job to the laser while setting up for the next cut. Paper and vinyl cutters have been doing this for years Getting up to go push a button just isn’t time saving or convenient in this case
Paper and vinyl cutters won’t burn your house down.
The requirement to physically push the button is so their lawyers can say you were in the room and that Glowforge is not responsible for allowing you (or some hacker) to start fires from across the internet.
