And so would he better off asking on a dedicated Forum for the K40 or here Gary?
In fact you advocated for separate Forum for Chinese machines back over on the never ending Glow Forge discussion.
it's just a statement of fact, and why I would advocate for a separate forum for Chinese lasers as a way to better serve each group.

Since you purchased on Amazon did you try to contact either them or the vender? Perhaps you got a bad set and I have had good luck with Amazon getting things right. It does say for K40 machines so there is no good reason why they won't work. BTW there is over 800 users on the FaceBook K40 group I found and there might be other groups (yes the other has over 2,000 members!) perhaps they would have suggestions, that you won't find here? I just joined the last one and there are some very good posts. It is the Chinese K40 Laser Group.

Sorry if this is a silly question, but are you sure you installed them the right way around? The shiny side should be directly towards the beam (not like a normal mirror where the shiny part is *under* the glass).
I just checked my Triumph spare mirrors, the back side is a dull silver-gray. The GCC spare mirrors have near black backs. The mirror that used to be above the lens in my LS900 is virtually identical to look at on both sides! I turned it around once, figuring it was 2-sided on purpose to save me from buying a spare! Bonus!
Nope- ... at full power it would barely mark Rowmark.
This reminds me of when I made a mirror out of a hard drive platter. Took my LS900 about 5 minutes to burn a hole thru it!
check out the beam spot in the mirror

This is one way to tell if your beam is in alignment

found out I made it from the wrong type of drive platter, oops... But I'm still trying to figure out how I was able to cut out this mirror in the first place, since it's GLASS!
