Knightrider,
I read your initial post and I have the impression most of your issues have to do with misunderstanding how certain collimation tools work. It is common for beginners to use laser collimators per given instructions to find out that the secondary mirror is not centered and rounded under the focuser and only part of the primary mirror reflection is visible. When that happens they get discouraged and assume the laser collimator is bad or assume they did not follow the instructions correctly. Bear in mind that the laser beam hits a tiny spot on the secondary mirror. Laser beams have no clue where the secondary mirror edge is located in reference to the focuser. Many assume that unless the secondary mirror is centered/rounded under the focuser they can never redirect the laser beam to the primary center and have the beam retrace its path all the way back. This is the wrong assumption.
Then you collimated with the Farpoint cheshire. Keep in mind that you can move your eye around until you can see the whole primary mirror and you assume the secondary mirror is collimated. But your eye axis is no longer in-line with the focuser axis.
Then you adjust your focuser by shifting the focuser axis to align it with your eye-axis. When that happens the laser agrees with the Cheshire.
I believe your collimation steps are not completely correct.
