Beam diverters good.
At first neither of two beam diverters worked, using Beckhoff driver. The sensors are good, the motors tried to move but they couldn't fully move the mirror.
We brought a beam diverter testor, and one of them (OMC_REFL_AIR_BDIV) moved slowly, but the other (AS_AIR_BDIV) didn't. The difference between the testor and the Beckhof thing is that the latter has a maximum current set in software, thus the tester is beefier.
When pushing the BDV by hand, it was obvious that the friction was big (and they both squeaked and squauked screeched). I loosened the front/back plate screws to make the plates more aligned with the axle, tightened them, and loosened the axle collar screw so there was more space between the front/back plate and the jewel bearing. This seemed to help, and after doing this for both BDVs the one that worked slowly started moving smoothly, and the one that didn't move started to move.
Switching back to Beckhof, the AS_AIR_BDIV didn't move. After another round of loosening screws and aligning, it finally started moving.
One thing is, open/close logic in AS_AIR_BDIV is reversed, which should be fixed in Beckhof.
Picos good.
We brought a picomotor driver and a testor because ISCT6 is not in position.
At first none of three AS picos (AS_A and AS_B for WFS centering, AS_C for AS QPD centering) worked, but QPD sled picos were good.
We swapped the in-air cable and the AS picos started working. Swapped the in-air cable back and the AS picos still worked.
One of the shafts for the in-air pico DB25 connector on the feed through was bent, and it was kind of hard to screw it in. Maybe the cable was not fully seated because of that.
Anyway, all picos work.
Note to self: M10 is the first pico on the QPD sled cable, M9 is the second.
Remaining tasks can be done from outside without going into the chamber (unless, of course, something is found to be bad in chamber):
