=== Summary of this week ===
 * Height adsustment: Target is ITMY 6mm upper, ITMX 5mm lower.
  * One of the stepping motor did not work. It seems current problem. It will be checked today.
  * ITMY adjustment was done. ITMX height changed ~2mm.


=== Discussion ===
 * ETMY will be used for mass feed back.
  * ETMY has high power coil driver now.

 * Matrix diagonalization for ETMY seems to be much smoother than ITMY. Not sure the reason but ITMY seems to have more coupling.
