The CoreXY system is a modified version of the E3D toolchanger printer. We changed the dimensions (outer dimensions 600x600x600mm) and tried to reduce costs by choosing off the shelf available parts and laser cut optimised plates.

We changed the original E3D spacers for the stepper motors and belts to normal M3 spacers.

The belt pulleys have standard spacers which are standard available without custom machining needed.
