Hi everyone! Welcome to my latest design to convert an Ender 3 v2 to CoreXY printer.

The Aim of this project was to build a converter kit for my V2 model into a Core YX printer and by reusing as many original parts of Ender 3 v2 as possible. The second goal of this build was to keep the possibility of converting back the coreYX to Ender 3 V2 and here we are.

The benefits of CoreXY system is that your ender 3 v2 doesn’t have to move the heavy glass plate anymore, so by addressing this issue now you can start to increase the printing speed with less impact on print quality.

build volume of 220 x 220 x 250 mm
