Sorry Bob, you've completely missed the point.

The **purpose** is to have more motor channels than physical
drivers (to save the driver cost). Yes, I'm multiplexing the drivers.

In the extreme case, only one physical driver, and 64 axes.
In a realistic case, 3 drivers, 8 axes.

Yes, I was thinking it would apply to your machine.

But with all my irons in the fire, if I were to design and build
this circuit, it might be another year or two until I got around
to it. Nevertheless, I put the concept in the public domain so
anyone can run with it in the meantime....
