x axis mods

I have been working on getting my mendel printing more reliably and have changed the orientation of the x axis motor. The main design puts way too much drag on the axis to print. or at least on mine. Also working on installing makerbot mk5 hot ends so have redesigned the print carriage so the mk5 head can fit between the rods. right now im printing it on my makerbot. Im also considering a mod of the x-z connections to widen the spacing of the rods, right now im concerned that the heat from the extruder may cause issues with the carraige regardless of the new design.
