Well I couldn't leave it alone :-)

One quick re-design of the z-axis stepper placement and I can't believe I didn't just go with this all along. Trying to save a few pounds on the z-axis I think was a false economy. This design has the ease of cabling of the previous but with lower z-axis weight as well. Double win, now I've just got to plug all the numbers for the z-axis parts into the spreadsheet again...
