Body: 

Downloaded the design values from edt with the 345_setup workspace and took some baseline pre-match harp swipes. These were pretty far off design, but not so bad as to be unmatchable. Ran zigzag for both planes with IHA0L10, which required a bit of fiddling to get the right K1 range. The match converged on the first try without having to open up tolerances and calculated quad setpoints seemed fairly reasonable. Harp swipes post match weren't great, but seemed like something we might be able to iterate on.
