For the records. GPS time 1078083583. Tripped on Actuators.
Level 2 isolation on both stages, no ST1-ST2 sensor correction on. Had been running on "Start" blends on both stages for quite some time, T240s were pleasantly green. Tried moving ST1 from "Start" to "TCrappy", tripped halfway through on actuators. First glitch in captured screen show is start of switching third spike killed it.
Since glitch appears much larger in horizontal, we'll try switching vertical first (Z, RX, RY), then horizontal (X, Y, RZ).
