Mike: No, I think the entire table-top moves on this, so the Y motor is
"down in there" under the table. A guess.
Does this EUR 1200,- price include the DRIVERS? Expensive just for the metal
parts in the view! And NO "quill motor"? Is one supposed to use one of
those awful things with sleeve-bearings wit 0.005" play?
Look in FILES; third one down. That is home-brew, with Thomson linear
bearings and Class-L way-shafting. This can be built with Xylotex drives and
Size-23/single-stack bipolar motors. Here, as I made this in '84, I used (old)
unipolar and home-brew drivers. HOT (wasteful) "ballast resistors". Never again!
