Paul,

That is what I may very well end up doing, except that I think I might
need to write a new canonical command 'trace polynomial curve' if I
want the system to react to the real world position of the carriage at
full rate with hard realtime reliability. It could I think actually
be done by just hacking the servo loop code so that the commanded
position of one axis is a function of the measured position of
another.

Note that this starts to look like the problem of rigid threading
without a tightly servoed spindle, only somewhat easier.
