The Voron V2.4 is a modified CoreXY design with a static bed and a gantry that moves along the Z axis. It is a much more complex build because it includes things such as 4-point gantry tramming to align to the print surface, dual MCUs, and other unique features. It is also designed to be fully enclosed so it prints ABS or similar filaments very well. Due to the linear rails the design is scalable in stock form from 250^3 and 300^3 all the way up to 350^3. More linear rails, larger print surface, and other V2.4-specific items make this printer more expensive.
