Back in 2017 I installed an hour meter inside the laser cutter that tracks time that the key is turned on. It would have been better to track hours where the laser was firing but we considered the approximation good enough at the time.
Anyway I'm sort of curious about how.many hours have been logged in the last 8 years.
At the time we were using this form to track maintenance: https://forms.gle/DAhtEVFvXVFmyrod6
Mostly in attempt to determine mean time between failure of components.
