WP 6140 FRS 4650 II 1151

DeIsolated ITMY HEPI and cranked on the DSCW Springs to put platform close to target position.  Succeeded generally; 1/12 turn of spring does ~30um shifts--about as small a turn as we can repeatably do (must turn multiple springs the same amount to get desired result.)  But, reduced the 4 horizontal Actuator Drives from ~5000 cts to 10s & few 100s, and, 3 of the 4 vertical drives a good bit.  See 1st attachment.

Different from the BS last week, looking at the local IPS positions, the local postions are pretty much what they were before the drag and drop.  All the IPS readings are within 2 or 300 counts, < 0.0005", see 2nd attachment.  Hmm, now that I revisit the BS numbers, the BS verticals maybe moved 2 or 3x the ITMY...  So maybe all in all not too big a deal given the overcontrolled/constrained nature of the HEPI.
