Recovery of F1 FR

• Tried to move the F1 FR. We used the slow micro steps and the full steps. The FR came back alive! Adjustable height range of keystone was 66.5 +/- 2.4mm.

Tuning of F0

• Compressed six blades to 8mm, 12mm, and 14mm from 6mm.
• Measured the dependence between weight on the F0 and height of the keystone in each compression.
• Expansion of adjustable height range of keystone is expected.
