Excellent!  Thanks for testing this one out!  Well, knowing only vaguely what
is in the trajectory planning, I suspect it is fairly CPU intensive, so you may

not be able to turn it up much more.  But, it is a big help to know that
doubling
the Traj execution rate helped it run through that engraving code.
