The wild oscillations are NOT gone, see the axis.2.f-error trace!  This 
will likely have ONE rounded transient at the
beginning and end of the move, but no continued sawtooth at all.  The 
error peaks at about 10 milli-user_units, which
I think are mm in your setup.  That is not such a huge error, but the 
sawtooth shape of it indicates the control loop is totally
NOT in control there.
