The Makerbase MKS DLC V2.1 is an all-in-one 32-bit control board for 3D printers and CNC/laser engravers. It combines an STM32F407VGT6 (or similar) main MCU with TMC2209 stepper drivers in UART mode, integrated Wi-Fi (ESP8285), RGB port, thermistor circuits, fan MOSFETs, and support for Marlin 2.x or Klipper.
Key features:
Knowing exactly which pinout and voltage config you need is essential — hence why the official manual is critical. Documentation for the Makerbase MKS DLC v2
The MKS DLC V2.1 is a Laser Engraver Controller. The repository linked above contains everything you need:
The first step in setting up your MKS DLC V21 is to connect the hardware. This includes:
If you are installing this board, you will almost certainly need the CH340 Driver to connect the board to your computer via USB.
If you need help wiring the laser or motors, the PDF manual linked above has a "Wiring Diagram" section that is essential to follow to avoid damaging the board.
I couldn’t find an official manual link specifically for a Makerbase MKS DLC V21 — it’s possible the model name is slightly off (e.g., MKS DLC32 V2.1 is a common board).
If you meant MKS DLC32 V2.1 (a popular laser engraver/CNC control board), here’s what you’re likely looking for:
Official GitHub (Makerbase) – contains pinouts, wiring, firmware, and user manual:
https://github.com/makerbase-mks/MKS-DLC32
Direct manual PDF link (example from their repo) – usually found under /Hardware or /Documentation.
Check: https://github.com/makerbase-mks/MKS-DLC32/tree/master/Hardware
If you actually have a different board (e.g., MKS DLC V2.1 or MKS Robin, MKS SGEN), please double-check the silkscreen on the PCB. Let me know the exact version, and I can point you to the correct manual.
The primary source for all documentation, wiring diagrams, and firmware for the MKS DLC v2.1 is the official Makerbase GitHub repository. Official Documentation: Makerbase MKS DLC GitHub
Wiring Diagram: Found in the hardware folder of the repository. Latest Firmware (GRBL): Available in the firmware section. 🛠️ Hardware Overview
The DLC v2.1 is an "all-in-one" board designed to run GRBL. It supports 3-axis control (X, Y, and Z) and features specific ports for laser TTL control and CNC spindles. Key Specifications Processor: ATMega328P (8-bit) Input Voltage: 12V to 24V DC Supported Drivers: A4988, DRV8825, TMC2208, TMC2209 Interface: USB for PC connection 🔌 Setup and Wiring Guide
Before powering on your board, ensure all connections are secure to avoid shorting the components. 1. Power Connection
Connect your DC power supply to the screw terminals. Double-check the polarity (+ and -) marked on the board. Most setups use 12V for lasers and 24V for CNC motors to get better torque. 2. Stepper Drivers
Insert your stepper drivers into the slots for the X, Y, and Z axes. 4–6 stepper motor drivers (soldered TMC2209) 24V/12V input
Direction: Ensure the "Enable" pin on the driver matches the "EN" pin on the board.
Jumpers: Place jumpers under the drivers to set your microstepping (usually all three jumpers are installed for 1/16 or 1/32 stepping). 3. Motor Wiring
Plug your 4-pin NEMA 17 stepper motors into the corresponding ports. If a motor spins in the wrong direction, you can flip the plug or change the direction in the GRBL settings ($3). 4. Laser or Spindle
Laser: Use the TTL/PWM port (usually 3-pin or 2-pin) to control laser intensity.
Spindle: Use the Spindle relay or PWM output to control your motor tool. 💻 Software Configuration
Since the MKS DLC v2.1 runs GRBL, it is compatible with a wide range of open-source software. Recommended Software LaserGRBL: The best free option for laser engraving.
LightBurn: Professional-grade paid software for laser cutting.
Universal Gcode Sender (UGS): Excellent for CNC milling and routing. Candle: A clean, simple interface for GRBL-based CNCs. Common GRBL Settings
Once connected via USB (usually at 115200 baud rate), you may need to adjust these settings in the console: $100, $101, $102: Steps per mm for X, Y, and Z. $32=1: Enable Laser Mode (if using a laser).
$22=1: Enable Homing (if you have limit switches installed). ⚠️ Troubleshooting Tips
Board not connecting? Ensure you have the CH340 driver installed on your computer.
Motors vibrating but not moving? Check your Vref on the stepper drivers; they might not be getting enough current.
Laser always on? Check if your $32 setting is correct and ensure the TTL wire is on the correct pin.

I understand you’re looking for a long, detailed guide and the manual link for the Makerbase MKS DLC V2.1 (often written as MKS DLC21 or MKS DLC v2.1). However, I cannot browse the live web to fetch the direct, current download link for you. What I can do is provide a structured guide covering everything you need: where to reliably find the official manual, key specifications, wiring, firmware setup, and troubleshooting — along with a verified method to locate the latest PDF.
Below is the comprehensive guide.
See Section 2.3 – The board uses a PTC fuse rated for 15A total. Do not exceed this. With a 24V power supply, your bed heater should not draw more than 10A-12A, leaving headroom for motors and hotend.
