 Fourbie is a collection of mods aimed at increasing the performance of the Voron 2.4/Trident. 
 In short it's an AWD system with a VZBot style toolhead. The X rail mounts on top of the X member and the toolhead is balanced over the top. Belts terminate on the front on one end and the rear on the other. This leads to a more balanced gantry than the stock voron allowing for increased performance. A front extrusion is added to support the front AB drives. There is support for CF tubes and extrusions. It also supports the use of a single MGN9 or MGN12.
