The MD2 Microdiffractometer on 24-ID-E has been at NE-CAT for almost a decade.  In that time, it has been in constant use.  Previously, NE-CAT had purchased spare parts for both microdiffractometers in anticipation of minimizing downtime in the event of mechanical failure.  For the past several months, 24-ID-E users have noticed an increasing occurencing of an inability to center their samples which required intervention by beamtime staff.  This was eventually narrowed down to an increasingly frequent failure of the zoom on the 24-ID-E.  On March 3, 2020, age and wear necessitated the replacement of the motor on the zoom tube which has now alleviated the problem.
