OK, you have selected a circular arc move, presumably in the
XY plane.
Then, you go from X=0 Y= -0.07 Z=4.15
to
X=0 Y=-0.14 Z=4.275 which is NOT a move in the XY plane.
But, if XY plane is selected,
then the extra axis should move the desired amount while the
XY arc is performed.
But, what exactly is the error? Is it a distance to end
does not equal distance from start?
