Team Vision for Integrated System Build & Test Phase
- The plan for this phase was to have a basic demo complete for the 3 axis motor drive system, have basic functionality represented from the print head, different homing algorithms, and a new mounting fixture integrated together. An unfortunate road block that we encountered was realizing that we received defective hardware. Thanks to the expertise of our guide and sponsors, we were able to pass this roadblock successfully.
Test Results Summary
Mechanical designs were implemented to the plan. The print head, image loader board, and wave form generator were revealed to have underlying issues with the hardware. After expert analysis from Xerox is was found that the waveform generator was shorted. This explains the issues the team encountered when trying to get the print head to jet. After we received functional hardware, we were able to have the print head to jet successfully. The implementation of the motors is on schedule. Limit switches were added to aid in the functionality of the motor homing and safety. Currently, different positioning algorithms such as "home", "print", and "test" are being written. The encoder was rehauled to make measurements more accurate. The UV film was obtained was found to be within specifications. Great strides have been made in the overall aesthetics and enclosure design.
Risk and Problem Tracking
The end status for this phase shows the tasks that we believed could be completed.
This phase had many more tasks to complete as were attempting to individually complete each subsystem. Below are some comments on our progress.
Plans for next phase
- We are continuing to put together a mid-semester BOM to submit to Dr. Cormier for approval and purchase.
- Additionally, we seek to complete the enclosure reconstruction and finalize our encoding scheme. Finally, we plan to work on our system for utilizing magnets to secure the printing surface, which is to be a small glass slide.
