one last thing so you dont go crazy, focal point and mirror alignment is not the same
Yes, I do know that 
I havnt yet done any testing to determine the focal point of the laser.
Yes, don’t take offense, all the way we joked after the post Jim said he found the error. +Peter van der Walt, I’ve got a good time with the vídeo. 
Jim Bilodeau, how many hours on your laser tube? If you’re losing power above 22c on your water temp., it’s telling you something…
1 hour so far
Edit: it may be more like 25C that the power seems to drop when current is set to 15+mA
