HI Guys!
I want to keep you up to date.
my problem is that my new 60W laser with 20-25% power on the first mirror always has a point with 4 “corners” when testing. the seller always thinks that this is normal because that is too little power for a 60W tube and it is not properly focused!
and now I just found that here in the forum:
Maybe the seller is right?
I have already threatened him with a lawyer and the same, but have now been offered to send the whole machine back. But I would have to pay shipping and I would get a new tube!
and now i think they are right, especially now that i read the post (see above).
What do you think of that?
with 50% power, for example, I have a nice big round burned-in point on the taped mirror 1
KInd Regards from Austria!
