When using the rotation stage on the pRESP motion phantom, the insert stutters or becomes dislodged, how can I resolve this?

Answer

The alignment of the pRESP motor drive to the body oval is critical when using the Rotation Stage accessory.  Even a slight rotational offset can cause binding of the insert during motion.  See Assembly and Setup of User’s Guide for alignment instructions.
