i did a test last night with a laser and cheshire initially my thoughts where that the laser was off, so i used the cheshire. then went and tested the laser at about 4m it was turning a 7cm circle. tuned it again to run < 5mm circles. the laser said the cheshire was so close its not funny.
I know how to collminate
aka i know what to look for in the cheshire
the laser doesn't require this type of knowledge just the knowledge that the laser itself is spot on.
once you understand whats happening ide go for a high end cheshire collmination set as it does the secondary tilt primary alignment and more importantly focuser tilt!
just trying to keep it fun and easy
bring in the other bits once the knowledge is there.
