Nice and tidy and always Jim.👍
Many lasers have output pins that can control air and fans through the file you are running. It can take some digging to find the info and of course making it all work, but in the long run it can make things easier.
I still have mine set up like you do, turn on the air assist, get the exhaust fan running and of course shut it all down when done. Have the plan worked out, just need the "kick" of a few ruined items due to forgetting to make me actually build it! 🤔
