Atleast it looks cool.

We completed our first test of the entire assembly. The x and z axes are working great but the y axis is horrible. First, it would only go down, then when we got it to go up it would sometimes slip. Once we got those problems fixed, we realized that when the sled would move up and  then down and then back up, to what should have been the exact same position,  it was about 5% lower than the origin point. We think we have a solution, but only the next test will tell.
