Since Glowforge recommends cleaning after 40 hours of use, can you please provide use-timers? Minimally one, but preferably at least two: 1 for total use, 1 user-resettable after cleaning. Think Engine odometer and Trip odometer. While you’re at it, a 3rd timer for “total use on this tube” would also be great. But I’d settle for the 1st two at this point!
Thanks! And have a glowing day!
