Thanks for the helpful problem report. I agree that this looks like
the earlier errors. The TCC tracking process timed out waiting for an
axis controller reply, and so initialized everything.
I also worry about the command "offset rotator
-8.4557439247492122e-05". Due to limitations in the TCC command
interpreter, exponential notation does *not* work reliably and should
never be used. I have filed a PR.
I'll look through the logs and report on timeouts on LTA19 and slowdown errors.
