I think you could probably create a kinematics that changed Z as W
moved. I am not sure how it would work out, but I am imagining that
if, for example the tool was 1" from the work and W was at 6" and you
programmed G0 Z3 W5 the effect would be a 1" downward move in the knee
and a 1" upward move of Z. (effectively the kins would make Z a
"slave" of W)

I am not sure how much it would help.
