First off I would like to thank everyone who voted for us in the first round of the Hackaday prize! We are honored to be in the top 15 and will wear our HaD shirts with pride. 

Exciting news in this update! We have officially begun manufacturing the components for the Z-axis. Corey is working on completing the spectra line pulley, square drive shafts, Z-axis lead screws, and motor couplers; With any luck we will have the parts for one side of the Z-axis assembled for testing within the next 2 days. 

The Spectraline pulley has been redesigned to make manufacturing easier and more cost effective. It is now a clamshell design with two locating dowel pins. It will be machined as two halves, assembled, and turned down as one assembly to ensure complete concentric with the square drive shaft. The specraline retainer has also been changed to a single #2-56 socket head screw, eliminating 4 parts. 

I'm starting to build up a set of engineering drawings for release, currently they are in a very crude form just to get the ball rolling on manufacturing. Once the parts have been prototyped (Not FDM printed, actual prototypes) I will clean up the drawings and release them. We are still playing around with a few different part numbering schemes, but will choose one shortly to simplify the drawing structure for the TOME. 

Here is another render showing that the new spectraline pulley still conforms to the original envelope. 

More coming very soon! Please follow us to keep up-to-date on our progress.
