Improved X-Axis for Anet A6

Hi, I re-designed it, because I wanted to use the Igus-Drylin bearings for the Z-Movement and I also didn`t want to switch the X-Motor via Firmware or by change the cable. So I remodeled this from scratch. It works pretty well for many prints right now, and there is almost no play in the Z-Axis. Better then the version with the original ball bearings.
