Green beam was almost clipping on PZT1 mirror and 1" fixed steering mirror downstream. This is because the path was set up before the arm was open. Now that we know a good angle of TMS, I changed the table path such that the beam was safely inside the mirror.

Restarted WFS path work but one problem is that the waist of the beam rejected by FI was much smaller than Bram's design (measured [91, 77]um P and Y, should be about 200-250um for the design to work).

The beam size injected into the chamber was [P,Y]=[2.09, 2.72]mm radius,  measured at around the splitter for Hartman (should be about 2.2 or so). The return beam size was matched to injection only in PIT ([P, Y]=[2.0, 1.7]). 

I adjusted the lens position (between PZT1 and PZT2) to split the error. Injeciton [P,Y]=[2.10, 2.66], return =[2.4, 2.1].

This made the waist of the FI-rejected beam larger (about 100um) but not enough. I'll see if I have a space to move things around to make it work.
