Super uppgrades for Creatr and Creatr XLprinters

Uppdate 24-11-2015
( I have uppdated the bearing blocks. https://youtu.be/QRKUzB4lhs4

The top rail is not nesseseary, the machine works perfectly, but beacause of the orifginal Creatr design the motor shafts keep failing due to metal fatigue.

The new blocks have reinforsments where needed and its made so you can remove the 2 nutts on the y axis bearing and move the motor sprocket inn in the axsle so the motor shaft wont fail. this new design has run for over 800 hours without insident.
