Spent all day moving top blade back and forth.

There are three problems with this approach, i.e.

1. Each time we move the blade, we need to REALLY check any mechanical interference, and we repeatedly thought that nothing was touching only to find later that something was touching.
2. There's no real feedback as to how much we're moving (though Jeff was getting better).
3. When loosening the blade PIT changes, and when tightening there's a large-ish YAW change while PIT doesn't completely go back (again Jeff was getting better to control this using smaller steps).

Tomorrow we might move the cage using pushers to address all three problems at once.

On a brighter note there were victories also, i.e.

1. Beam diverter moves. And we even found that "open" and "closed" logic are reversed. Success!
2. Picomotor GUI was fixed though we didn't test the picomotors. Success!
