I'm using this motor to turn a shaft.  I have all of the inputs in a static
state with the clock signal turning the motor.

With the motor not connected it is silent as it turns.  When I mount it on
a metal block so that it meshes with the gear of the shaft it puts out a
rattle as it turns,.

I found that if you press down on the stepper it doesn't chatter so much.
We put a neoprene gasket under it which helped quiet it but it was still a
noticeable chatter.

We then mounted a plate on top with a neoprene gasket lightly compressing
the stepper.  This quieted it quite a bit.

Is this a common issue with steppers or am I not doing something
correctly?  Lastly, does anyone see a problem slightly compressing it?

Thanks
