ReP_AL Core XY 3D Printer Axis Upgrade

Upgrade to the Y and X Axis ==== The modification integerates the Y axis bearing rod into the stepper motor bracket, giving an extra 25mm of space for Y axis travel. The X axis is also spaced out by a further 20mm. Additonal spaces can be printed and used to extend the Y axis further backwards. Useful if you have a large Hot End head assembly. There are also 2 new Y axis carraiges which alow the GT2 belt to pass through on the way to the GT2 pulley gears on the steppers. Thuis keeps the belt nicely aligned and in straight lines. The new bearing stack blocks are screwed in-front and behind the bearing carraige which gives a better clamping action. In the previous design a heavy belt tension could result in a gap between the bearing block and the Alu frame (twisting action). All the other parts from the original design can be used.
