It’s a long time since i started my very old M900 to Laserboard conversion. I think its working how it should be right now.
It does’nt cut that well, it only engraves. The tube should be a 60w but i think it’s around 10y old. Can those tubes less powerfull in years even when not used? Got a sparetube with it, but don’t know how old that one is.
Basically " All glass CO2 laser tubes degrade over time with lifespans ranging from as little as 3 months to 3 years. Basically, the CO2 inside the tube breaks down into Carbon Monoxide and Oxygen with use. If you overdrive the tube, it just accelerates this process and reduces the working life."
If you have an “unused” tube that has been sitting on the shelf it still should be good as no gas break down would have occurred. On the other hand some gas may have escaped.
I guess I was not clear.
I just quoted a section of what was in the first link I supplied from LaserUser.com that got highlighted on the forum in its own box… That first article stated 3 months to 3 years shelf life and was what I had put in bold and put in quotes…
The second link I supplied which only showed up as a link stated they had put in a spare tube they had gotten in 2011 into a system in 2017 and it worked fine.
You are correct in that the articles seem to contradict each other.
My only Experience on tube life is the FLS 5th generation we have at work that was purchased back in 2014. That system had limited use for 2 years but after conversion to a Cohesion3D Laserboard the tube still seems to be strong 6 years later even with a 4 year break of non-use. It still engraves and cuts with only a 45 watt laser. The original poster had a 60 watt laser that would only engrave and wondered about age degradation and if his spare tube would work.
I would agree that “buy cheap, get cheap” and that tube manufactures will vary in construction. It might be his spare tube will work just fine depending on how it was manufactured or it might not be any better than the tube already in his system
As you already pointed out “Redsail” is the Red flag here.
