 == Conclusion ==
-Conclude your project here.  You can recap your testing and problems.  You should address the "so what" part here to indicate what you ultimately learnt from this project.  How has this project increased your knowledge?
+This project has ultimately given me more experience with full system engineering. I feel like I have a complete mastery over the software side of this class so it was really interesting to try my hand and more PCB design and system integration. Although a failure in this class, the lessons learned here will help me in CmpE 195B and in future endeavors.

 == Testing & Technical Challenges ==
-Describe the challenges of your project.  What advise would you give yourself or someone else if your project can be started from scratch again?
+Given another few weeks on this project, it could have been completed. A large portion of the learning from this project was in the hardware assembly phase. I learned that to effectively design and implement custom PCBs with SMT a good rework station or oven is required. I will be purchasing these items in the very near future.

		+	For this project the task will enter the workflow at the flex scanner stage. from here we can manually generate move, line, and curve primitives which can be queued into the curve queue. For this project only one static graphics stack will be required and therefore graphics opcodes will not need to be decoded. Additionally a graphics stack will not be required. Once a set of curves is queued and a stroke command is sent, the cut_curve task will be started which will then perform the actual motor control movements.

 This project was ultimately stopped by a lack of manufacturing hardware. The Allegro stepper motor driver chips use a eTSSOP-24 SMD pad layout. This means that the pin pitch (spacing between pins) is only 0.6 mm. This proved too hard to solder by hand. In order to resolve this issue, a solder paste mask is required. This would allow solder paste to be applied to the pads only and would limit the amount of pin bridging. Due to time constraints it is impossible to order one of these in time for demo.
