Or use Rutex. They have a greater lock range.
One should be able to take a fine resolution encoder and divide
it with simple 74XXX logic to get whatever resolution they
are looking for. Correct? But it sounds like a big tradeoff
with performance. Is this a shortfall of the Geckos?
What is the minimum resolution for fine finishes with the servo
+/- 1 count servo dance?
