CoreXY Kinematics
CoreXY is an advanced 2D motion mechanism used in modern high-speed 3D printers where two stationary stepper motors drive the toolhead along the X and Y axes through two intersecting closed-loop timing belts.
CoreXY kinematics print faster with less moving mass, lowering machine hours per part at the same hourly rate. The result is a lower cost per part without changing material spend.

In CoreXY printers, both the X and Y stepper motors are mounted rigidly to the frame rather than on the moving axes. Running both motors simultaneously in the same direction drives diagonal motion, while opposing directions produce orthogonal movement. This keeps the printhead exceptionally light for ultra-fast accelerations.
Belt Tensioning & Racking Diagnostics
Because CoreXY relies on two long belts of identical path length, maintaining equal tension across both belts is critical. Unequal belt tension causes mechanical "racking", resulting in oval circles and skewed 45-degree diagonals.
CoreXY vs Cartesian Bedslingers
Unlike Cartesian "bedslingers" that fling the heavy heated bed back and forth on the Y-axis, CoreXY machines only move the bed downward on the Z-axis. This eliminates layer-shifting inertia on tall prints and enables speeds exceeding 500 mm/s on modern machines like Bambu Lab and Voron.
