In the Darwin, how much of the precision is dependent on the motors, and how much is dependent on the gears/rods, etc? If we wanted more precision, could we get it by using a fancier driver to run our stepper motor at 1/8 step, or more? It might not matter how precise the motor is, if the gears and rods to which it is attached do not have the same precision.
Could a cheap 200 step/revolution motor be driven at 1/2 or more steps and equal or exceed the performance/accuracy of the more expensive motors, and save money?
Lastly, what are the required specifications of the motors such as holding torque, shaft diameter, etc, so that we can pick alternate motors that will work with the Darwin design?
