    Mechanical design constraints in many cases can present difficult and unintended motion control challenges in many instruments such as frontend slits, insertion devices, mirrors and monochromators. Design decisions for meeting science requirements often times introduce control stability issues that seldom arise in non-scientific equipment. The Delta Tau motion system is an extremely versatile platform for this control, but also presents a severe learning curve as a result of the versatility. This presentation will demonstrate how subtle geometry effects can create large control problems, and how to look for those subtle "opportunities."
