There is a method to my madness, to wit I really want to know how good, or bad the tinyG is. Older version of the emc interp but a much faster cycle time. Glass scales are problematic for velocity control but rather good for position. Servos on that machine with good encoders on the ball screw were much better at velocity control, roll that in with a glass scale for position and you have the best of both worlds.
