MSD I Overview

Revised Scope and Summary

Note: Approaching the end of MSD I a scope change was implemented and required a rework of MSD I requirements. The original goal required measuring frequencies from two different cable configurations for a table-top gantry less printer. In addition to measuring the frequencies, this involved designing the configuration using IP from Oak Ridge. However, due to a change in our customer and scope our current goal is to design a 7-point connection table top gantry less printer. In addition to designing the configuration, our team will also measure the cable tensions of this 7-point cable configuration. The system will be capable of moving in the XYZ direction.

Below is a breakdown of what the team managed to accomplish since the last phase review up till the 2nd week of MSD II:
