That chess board has seen a lot of time under the cnc, I like it!
I stunk up the garage the first day I had my laser running. I was burning things for hours and hours. Smelled horrible the next day and I had both doors open. I need a really big fan, for you inside, probably a large charcoal filter minimum, I think you should really try and get that to vent outside though.
I added that video to the playlist, let me know if you want me to take it off. It is an unlisted video.
