SRM Surrogate X, Y, Z Alignment Complete
IAS: J. Oberling
SUS: J. Bartlett
Took a first look at the SRM surrogate (SRM-s) today and lo-and-behold, no adjustment was necessary. 
The cookie cutters did their job and placed the suspension within spec for X, Y, and Z axis positions. The position errors are below:
The cookie cutters did their job and placed the suspension within spec for X, Y, and Z axis positions. The position errors are below:-
X axis (lateral): -1.5 mm (south)
- Tolerance: ±4.6 mm
-
Y axis (longitudinal): +1.3 mm (west)
- Tolerance: ±3.0 mm
-
Z axis (vertical): +0.9 mm (high)
- Tolerance: ±3.0 mm
I have begun and mostly completed the setup for the rough pitch/yaw alignment of the SRM-s. This will be completed tomorrow morning and the rough pitch/yaw alignment will follow.
I ran quick V and R TFs and the sus looks healthy to me compared to old references that Arnaud left me. I need to dig up a good L reference TF and run that in the morning, but then we should be good to go on the pitch/yaw tuning.
And L looks good, too!
