Lockloss and recovery 01:02

1st Attempt:

1:12 IA

2:20 HA! I WIN! (green arms) Both arms were hosed. I got NO love from trending/resetting witness sensors or sliders. I used oplevs for limit references and aligned by visual and very zoomed in ndscope.

2:30 then X did this (see below) :/ - not winning.....yet

2:58 Green Arms finally done!

3:15 IMC unlocked after input align - having trouble re-locking itself - it seems the laser power is still at 9.5W

3:18 Decreased LP to 2W - Cycled IMC guardian - locked

3:30 IA complete - sort of (Mich Bright didn't work)

I re-ran IA Guardian a couple of times just to e sure I didn't interrupt anything

2nd Attempt

3:31 gonna take a swing at re-locking.

3:54 re-locking going ok - at ENGAGE_SOFT_LOOPS
