Why is there excess motion of the pipette tip during manual adjustment on my THORLABS PCS-6000?

If you notice excess motion of the pipette tip during manual adjustment of your THORLABS Controller, it's often due to instability from loose mechanical connections or dirt between surfaces. Ensure all screws are tight, including those on rotary and pivot stages, headstage mount, linear stages, and the mounting system itself. Also, make sure mating surfaces are clean and free of any debris or burrs. Check for vibration issues from wires and ensure the mounting system is stable.
