That was what I was meaning, yes. What were the settings for
MAX)VELOCITY and MAX_ACCELERATION that you used with those values?

Overshoot-and-return seems very odd indeed, I would only expect to see
that with a PID component in the loop. I guess that it might be
possible to see it with an accelleration calculation from an overshot
position.

I find myself wondering if your velocity commands are exceeding the
width of the register access to the Mesa card. I would need to look at
the driver code to see if that is possible.
