No exciting progress today. I did PSL green alignment for the Yarm, although I now think that the Xarm green needs realigning too.
Also, I was foiled for a while by ETMX jumping around. I think it's because the adapter board on the Xend rack didn't have any strain relief. So, I zip tied the heavy cable in a few places so that it's no longer pulling on the connector. Hopefully we won't see ETMX misbehaving as often now, so we won't have to go squish cables as often.
