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.
Using the manual, verify these five points:
Jump to the “Pin Definitions” table. This is your cheat sheet for configuring Marlin’s pins_MKS_DLC_V2_1.h or Klipper’s mcu.cfg. Pay special attention to:
One of the most overlooked sections is the circuit schematic. If your board is not powering on or a heater fails:
Most Voron builders pair the MKS DLC V2.1 with Klipper. In your printer.cfg, reference the manual to find the correct [mcu] pins. Example snippet:
[stepper_x]
step_pin: PE2
dir_pin: PE4
enable_pin: !PE3
microsteps: 16
rotation_distance: 40
All pin names in the manual match what Klipper expects. Cross-check the “MCU Pin Mapping Table” in the last pages of the PDF.
Open the manual to Page 4 (Board Layout). Compare the silkscreen on your physical board. The V2.1 has a white “MKS DLC V2.1” label near the USB port. Using the wrong manual (e.g., for V1.0) will cause incorrect wiring and potential short circuits.
printer.cfg from MKS DLC sample in klipper configs.ls /dev/serial/by-id/* to find USB path.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.

The Makerbase MKS DLC v2.1 stands as a cornerstone for DIY CNC and laser engraving enthusiasts, bridging the gap between digital instructions and physical creation. Based on the robust ATmega328P microcontroller—the same heart found in the Arduino Uno—this board is optimized for the GRBL firmware, a high-performance, open-source standard for controlling motion.
What distinguishes the DLC v2.1 from a standard microcontroller is its integrated design. It consolidates power management, stepper motor headers, and specialized interfaces for lasers and spindles into a single, compact footprint. Its versatility is its greatest asset; with dedicated pins for TTL laser control and dual Y-axis outputs, it simplifies the complex wiring typically associated with gantry-style machines.

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:
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.
