but today I had a clear moment, and closely inspected the laser opening with a magnifying glass
MAKE SURE IT'S NOT TURNED ON !!!!!
and I saw at the edges of the glass bar some plastic residue that covered the lens a small bit.
I took a very thin scalpel knife and cut it away, the glass is hard enough that it should not be
damaged by the blade.
and I was able to cut a big portion away, this cleared up the noise by 95%
so I'm a happy camper, but probably have to rescan everything I have done up ti'll now
.I hope this is also a solution for other noise problems users !
