I spent a bit trying to align everything by hand with ISC_LOCK paused in DRMI, misaligning PRM and SRM to adjust the BS then aligning PRM to adjust it then SRM. Still the same behaviour on PRMI as yesterday even with turning down the MICH and PRCL gains, and despite good flashes on DRMI it wasn't able to lock after my adjustments, I had to move SRM a lot. The wind is also picking up which is not helping ALS.
I talked with Sheila who had some more suggestions, gain lowering/raising and a template to run if I'm able to get PRMI locked, She's on her way back into town and might be able to help more in an hour or two.
Increasing the ramp times of MICH and PRCL and reducing the gain even more of MICH (2.8 to 2.5) and raising the gain of PRCL (6 to 8) has allowed us to survive longer. After this we keep losing lock at different points in the ISC_DRMI PRMI code, the furthest I've made it was PRMI_WFS_CENTERING.
I was able to lock PRMI finally and go through ASC by increasing the ramp times of both MICH and PRCL from 2 to 5, further decreasing the gain of MICH from 2.5 to 2.2 with als and 2.8 to 2.6 without arms and with PRCLs als gain being raised from 6 to 8. DRMI still wasn't able to catch after 1 round of PRMI, I'm holding in PRMI_ASC to take a quick OLG measurement of PRCL and MICH.
