A CoreXY printer will have a square, cartesian design, which is different from a Prusa in that the print bed moves only on the vertical Z axis, while the print head moves on the horizontal X and Y axes. It is distinguished from the similar H-Bot printer because the much longer belt and pulley system used in a CoreXY system eliminates the excess torque that causes faster wearing in the belts and gantry.
CoreXY printers are typically cube-shaped, and on higher-end models will include an enclosure. The print head moves by employing two long timing belts, each of them connected to a stepper motor. Depending on which way each motor is spinning, the print head will move in different directions. An interesting quirk of the CoreXY design is that the print head will only move diagonally when a single stepper motor is activated.
Due to the design of the frames and the way in which the axes move, CoreXY printers have a number of advantages over other 3D printers, but at the same time, there are also some downsides. In the following article, we will be exploring both the good and the bad to determine whether CoreXY designs are really worth looking at, or if you should just stick with the more popular designs that are flooding the market.
