Signum CoreXY/MGN9 Conversion

Important note: I published an updated version here: http://www.thingiverse.com/thing:1278086. It includes 3 MGN9 rails, 2 for Y axis and 1 for X axis. It was tested and works pretty well, see the photos and videos. I didn't work on full BOM and assembly instructions, it's mostly the same as in original project although you will need more short hex head bolts and nyloc nuts for rails and pulleys. If you have any difficulties assemblyng the projects drop me a message, I will answer shortly.

List of changes (compared to original project by 3DSIGNUM):

1. CoreXY kinematics instead of H-Bot.
2. 8 mm leadscrew, 10 mm smooth rods on Z axis.
3. 182x202 mm heated bed.
4. E3D v6 hotend.
5. LM8UU replaced by Igus RJMP-01-08
6. HIWIN MGN9 rails L=200mm / MGN9H blocks.
