Yes, this is an important point - that we have learned the hard way. We were about to throw in the towel trying to tune our machine. We have some fairly torquey (I can't believe that is actually a word:-) ) motors given the mass of the machine. We finally got a little education on servos and ended up changing our gearing from 2:1 to 5:1 (and using an initial 10:1 gearbox attached to the motor). This made ALL the difference in the world. The machine runs smooth as silk now as there is a constant load on the motor to overcome the 10:1 gearing.
