Laser tube & mirror alignment

im having a hell of a time lining up my mirrors. to the point where I think its the tube that may need to sit differently however I cant for the life figure out which direction to elevate or level off. I’ve used this:
for the last tow hours to attempt to get everything aligned and im still off, most of the issue comes when I pull the laser head closest to me and farthest from the laser tube that is aimed at mirror 1.
Close to the laser head it lines up great. bottom left corner, great all lined up, as soon as I move it to bottom right, the beam is off the laser head completely. if I adjust it at all, then non of the previous two positions line up.
Does anyone have a more comprehensive guide perhaps or is this just a trial and error thing until one day I finally get it?
