@Owen,
The new arms look great! Tks for posting the video.
Hysteresis, Brownian motion, White noise:
Am I seeing hysteresis (string lag) at the start of the first movement?
I don't envision it being an issue with all 3 arms in motion, and printing a raft will also account for it.
I think you're just seeing a pause before the arm began moving. I was filming with my iPhone held in one hand and reaching for the mouse with the other, so there was a brief wait while I entered the move command. If you watch closely you can see the top of the pulley turning, and I think that's exactly in sync with the arm motion. Certainly there doesn't seem to be any hysteresis at all.
