The Makerbase MKS DLC v2.1 is one of the most reliable and affordable control boards for desktop CNC routers, laser engravers, and writing machines. Powered by an ATmega328P microcontroller, this board runs GRBL firmware seamlessly, making it a favorite for DIY builders and hobbyists alike.
A dedicated 3-pin or 2-pin header labeled TTL/PWM outputs a 5V signal to modulate laser intensity.
Direction port invert mask (use this if an axis moves backward).
Connect a 12V or 24V power supply. Ensure the polarity is correct (Positive to VIN, Negative to GND). 2. Stepper Driver Slots

Before we dive into the manual, let's take a look at some of the key features that make the MakerBase MKS DLC V21 such a powerful and popular 3D printer controller: The Makerbase MKS DLC v2
Look at the "DIR" and "GND" pins printed on the board and match them to your stepper drivers (e.g., A4988 or DRV8825). Installing drivers backward will burn out both the driver and the slot.
Best choices if you are configuring the board for a physical CNC router milling wood or plastics. Step 3: Configure GRBL Settings
