[sudo-discuss] Re: hello again, & laser cutter concerns

So, based on Jake's last email (not sure why it's not on this thread), have we arrived at a temporary moratorium until the laser cutter ventilation system is reinstalled/fixed/revamped? Personally in favor of this, due to the long term health issues improper ventilation can cause. Based on that email, it's sort of sounding like smaller temporary fixes are not working.
