It appears that my laser has lost collimation, as the rotation trick is no longer working. Rotating it in the focuser traced out a circle about 5cm in diameter.

I don’t know how your laser got so badly out of whack, but 5cm over the length of your tube is pretty substantial. I wish you luck in colllimating your laser - in my experience this was possibly one of the most frustrating things I’ve ever tried to do. A proper V-block would possibly be a better guide to how aligned it is - I found that anything less than a perfectly snug fit in the focuser will present apparent mis-collimation. Good luck!
