CoreXY

CoreXY is a technique used to move the printhead of a 3D printer or the toolhead in CNC machines in the horizontal plane. The advantage of this technique is that the two motors used to perform the movement in the horizontal plane are stationary and do not have to move themselves, which can result in less moving mass. Instead, drive belts are used which are connected in a slightly intricate way[1] to provide movement in the cartesian xy plane.

Movement

For movement along the x-axis, both motors must rotate in the same direction. For movement along the y-axis, the motors must rotate in opposite directions. If only one motor rotates, the movement will be diagonal.

The movement can be mathematically described as follows. If is the movement of motor 1 and the movement of motor 2, the movement in the X and Y direction is given by:

Compared to conventional printers

Other cartesian 3D printers which do not use the CoreXY technique most commonly also use two motors for the xy plane, but where one motor is independently responsible for movement along the x-axis, and the other independently responsible for movement along the y-axis. This is sometimes called a "Cartesian technique".[2]
