Mks Dlc V21 Manual Link — Makerbase

Connect the 3-pin cable (VCC, GND, PWM) from your laser module to the dedicated TTL/PWM port.

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.

Ultimate Guide to the Makerbase MKS DLC V2.1: Manual, Pinout, and Setup

Verify $32=1 is enabled. Check the wiring with a multimeter to ensure the PWM signal pin is fluctuating voltage when a low-power fire command is sent.

The official manual is the single source of truth. Use GitHub search MKS-DLC21 manual and look for the PDF in the hardware folder. No live link is guaranteed, but the path above will always lead you to the most recent version. makerbase mks dlc v21 manual link

Compatible with MKS TS24/TS35 touch screens for operation without a PC. Common Wiring Setup

Before diving into the manual, understanding the board’s architecture will make the documentation far more useful.

is a widely used control board for desktop CNC machines and laser engravers. As an 8-bit controller based on the ATMEGA328P chip, it is designed for simplicity and reliability when running GRBL firmware.

You can find the most up-to-date manuals, wiring diagrams, and firmware files directly on the Makerbase GitHub repository: Connect the 3-pin cable (VCC, GND, PWM) from

Plug your stepper drivers into the board. Ensure the driver orientation is correct (aligning the EN/Enable pins on the driver with the EN pin on the board).

Insert your stepper drivers into the slots for the X, Y, and Z axes.

Ensure stepper drivers are oriented correctly before powering the board, as reversing them can permanently damage the drivers or the mainboard.

If using a 3-pin laser module, ensure the pin order on your laser cable matches the MKS board layout exactly, as wire colors can occasionally be flipped by manufacturers. Firmware Configuration (GRBL) Ultimate Guide to the Makerbase MKS DLC V2

Use the SPINDLE ports to connect a relay module for switching a traditional routing spindle on and off via G-code (M3/M5 commands). 4. Endstops (Limit Switches)
