My final parts have trickled in, so for the next week or two I will be able to finalize my design. Hopefully, I will begin construction after this coming week. 

I have considered tweaking my original design, as I originally planned to only use the rails. However I may be able to also incorporate the block carriage into my design, as long as I'm careful. This could potentially allow for smoother motion in the final project. I'm slightly concerned about the width of the guides, but I believe I can make it work. I should be bringing in my instrument next week to make sure of these measurements.

Over the next few weeks, I will continue working on the motors as well, to ensure they are all working properly.
