Hello:

Would your Father-in-Law accept manual control using switches to move the
head manually? You could have a manual speed control so you could control the
speed with which you move the axis and use the pushbuttons to position it.
If you plan on having a totally mechanical manual control then you will have
problems. If you make it easy to move then more than likely the accuracy will
suffer as I think you already know. If you make it so the accuracy is good,
the mechanism will likely be very stiff and hard to move, especially in the
up direction. On most of the CNC machines I have seen they have the manual
speed control with an axis select switch and you move that axis with
pushbuttons.

Hope this sheds some light for you.
