Hi all,

i am having trouble with aligning laser beam on a 130x90cm 120W chinese laser. It seems like when laser head is close to me in front it is centered, but more it goes to back of the machine it is pulled diagonally up and right. I made 9 different measurements in different parts of machine.

LR= Left Rear
LC= Left Center
LF= Left Front

CR= Center Rear
CC= Center Center
CF= Center Front

RR= Right Rear
RC= Right Center
RF= Right Front

I am attaching image of targets and where the beam is hitting. I dont know which part of the machine needs to be adjusted at this moment, 1st, 2nd mirror or perhaps tube angle?

And thing is laser is centered on 2nd mirror at all distances...
