I'm not too sure I understand. The way I might want to use this is as
an A axis, ie. parallel to the
X axis. Now, in the simple case, where the Y axis is such that the
spindle (Z axis) ir right over
the A axis, then Z moves directly change the radius. You could easily
make the demand that
Y=0, Z=0 is the origin of the A axis. Then any moves in the Y and Z
axes can be easily converted
into radius from the A axis. Is this what you meant above?
