4DOF Lead Screw Flexure

This 4DOF flexure relieves lead screw overconstraint in the z-drive mechanism. Hidden inside the structural tube, this flexure is compliant along in the x, y, theta x, and theta y directions and mates the z-drive lead screw to the carriage. These degrees of freedom ensure that the carriage’s z-travel is purely guided by one rail and not impacted by the lead screw.
