prusa i2 goes core xz

pinshape

I had an old Prusa i2 frame collecting dust, its parts mostly used up for my Mendel Max build. I decided to breathe new life into it by converting it into a CoreXY (Nicholas Seward's design) machine, which would eliminate the z-screw problems that had plagued me. With this setup, I now have a printable area of 190 x 200mm. I've opted for 625VV bearings and 18mm aluminum spools to ensure smooth operation.
