MakiBox - Anti-backlash On the Way

I had planned to get the z-axis in place and do up a video of that today, but after our weekly lunch show and tell we got going over the current mechanism and looking for areas that need to be improved.

We've found some variance in the thread widths (not the pitch) on the drive screws, enough that we need to design a simple anti-backlash mechanism in to counter shifting when changing direction. This was something we anticipated, so not a suprise.

The photo is what we drew while talking through the options for how we can fix it, to give you an idea of our process. 

At the end of the discussion, we were happy with the general direction, and are going to sleep on it and detail it tomorrow.
