A roller type I believe is how my SWI dro works on my mill. It
bassically has a rubber? wheel which rides on the flat surface of the
table and has an encoder connected to it, as opposed to a rack and
pinion or a glass scale.
The roller type is great for inexpensive machines as I would assume
that it will not hold position after many cycles back and forth, but
for Joe average, who does 3 or 4 pieces and then changes setup, it
works out real well.
