BSC3 status

Since SEI/IAS/ACB people were still sorting alignment issues with the ETMx cartridge, we hopped into BSC3 to make some progress on ITMx.  SEI still needs to finish payload and balance but we suspended the masses in prep for controls testing and future alignment.  We added the witness plate to the suspension and removed all temp payload EQ stop bars.  Payload is correct for SEI balance.

With Arnaud, we reset all 12 top stage BOSEM offsets and gains (to compare with test stand values) and then set the OSEMs to 50% OLV.  We attempted damping, but both chains had watchdog trips within seconds of enabling the DOFs.  We have rechecked that we do not (think) we have mechanical rubbing so will revisit the software/EE guys for further assistance.
