Voron legacy shorter X Carriage with klicky NG

the voron legacy gantry is unecessarly long when not using the stock probe. this shortens the gantry by 14.85mm (which is a lot !) and include a built in klicky NG. 

this makes the center of mass closer to the linear rods making the printer much stiffer, improving print quality

history behing it:

I built an unecessarly big voron legacy. mine is 310x310x200 build volume, and the long linear rods would bent more than I was confortable, which resulted in slower print speeds and not that great print quality. this mod + using a ligher carriage (dragon burner) resulted in much better and consisted print speeds and print quality on such a larger printer.

Shortened x carriage by 14.85mm, removed other probe mounts, added klicky NG mount
