I was wondering if anyone could help me figure out why I am getting unwanted stops during one of my operations.  The code is to cut a collar of varying depth into a curved part using the z axis and a rotary table (b) mounted horizontally, and should be one continuous cut.
The rotary dimensions are in degrees.
Here's the G code:

z    -3.7984    b    14        (position    20    )
z    -3.7982    b    12        (position    19    )
z    -3.7980    b    10        (position    18    )
z    -3.7978    b    8          (position    17    )
z    -3.7976    b    6          (position    16    )
z    -3.7974    b    4          (position    15    )
z    -3.7972    b    2          (position    14    )
z    -3.7970    b    0          (position    13    )
z    -3.7972    b    -2         (position    12    )
z    -3.7974    b    -4         (position    11    )
z    -3.7976    b    -6         (position    10    )
z    -3.7978    b    -8         (position    9    )
z    -3.7980    b    -10       (position    8    )
z    -3.7982    b    -12       (position    7    )

I've messed around a bit with the break angle, facet angle and corner tolerance, but with no effect.  The stops almost seem like they are not full stops, but could be my imagination since the acceleration on the rotary tables is pretty low.
