If you are building a high-performance 3D printer—especially a Voron, V-King, or custom CoreXY machine—you have likely come across the MakerBase MKS DLC V2.1. This compact yet powerful controller board is a derivative of the popular open-source design, known for its smooth stepper drivers and clean power delivery.
