So.. thought crossed my mind in looking at a used Co2 laser with Ruida controller. When I think, I get dangerous. @LightBurn, is there any way to tell and have LB report whether the tube was used for 40 hours at 90% power vs 40 hours at 15-20% power? 
To me this would tell prospective buyers whether the machine was abused most of it’s life or just mediocre usage.
Lightburn can only talk to the controller. Unless the controller has stored all of this data, there is nothing more Lightburn can tell you.
I think the best data we know about is Edit → Get Controller Info
It has a couple of drawbacks… Total on time refers to the Ruida being powered up, not doing anything. Job processing is pretty evident, but anytime you run a job this ticks. May have some use. It’s displayed on the machine console for each job.
Laser on time just means that it thought it was actually lasing.
I do a lot of looking around, so I’m sure my laser time isn’t correctly reflected.
Finally, there appears no way to reset items like laser on time, so if it’s replacement tube 1, 2 or 3, it’s not going to add much.
Conversely if you did have the data, you can set it up to only run 70% power at 100% in Lightburn, so could be in the same boat. So you have to define what abuse is.
If you find something else, please let us know.
I’d suggest you check the TEM mode of the tube, that will tell you if it’s working or not. I’ve seen these tube broken on arrival and some still alive after 7 years of 8 hours a day. Predicting tube life is a lot like predicting our own life, it’s pretty hit of miss…
The controller itself is what’s recording the information, and we’re just displaying it. What you see in that dialog is all that’s available to us.
thought so, just wanted to check. thanks Oz
