This machine has some sort of feedback from the motor. Has to (unless
it's a stepper system). The purpose of the linear encoder is to track
actual postiion regardless of backlash or lead screw pitch error.
While I understand drives and motors should matched to the loads, my
concern has nothing to do with that issue. My question has to do with
introducing a potentially flexible link between the motor and the
encoder that is tracking the motor. Yes, I understand modern belts flex
very little, but there is some. Does this pose a problem, is the
question.
