Updating firmware improves performance and fixes issues. Here's a quick guide:
Look for the green screw terminal labeled VIN and GND .
Makerbase maintains an active open-source repository for all of their hardware. You can find the official schematic diagrams, pinout maps, firmware updates, and basic user manuals directly on their GitHub page:
If a yellow warning icon appears under "Ports (COM & LPT)", download and install the CH340 driver. Note the allocated COM port number (e.g., COM3). Step 2: Choose Control Software The board interfaces with any GRBL-compatible software:

3 Axes (X, Y1, Y2, Z) — Note: The board has four driver slots, allowing you to clone the Y-axis for dual-motor gantry setups. Connection Type: USB (CH340 USB-to-Serial driver)
Crucial Step. Always check the pin labels (GND, DIR, STEP) on the bottom of your driver carrier board and match them to the markings on the MKS DLC v2.1 board. Inserting a driver backwards will destroy it instantly upon powering up. Limit Switches (Endstops)
Insert the included jumpers beneath the driver chips to set your microstepping (typically all three jumpers are installed for 1/16 step on A4988 or 1/32 step on DRV8825). 3. Motor Connections
Combines the functionality of an Arduino Uno and a RAMPS board into a single unit. makerbase mks dlc v21 manual link
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.
If you need to update or change the firmware from a CNC setup to a Laser setup: Download or XLoader .
If your CNC machine uses two motors to move the Y-axis gantry, insert a driver into the 'A' slot and use the onboard jumpers to configure it as a clone of the Y-axis. 3. Laser and Spindle Control
Check that your laser's PWM wire is connected to the TTL/PWM pin, not the continuous 12V/24V power pins. Ensure laser mode is active in GRBL settings ( $32=1 ). Updating firmware improves performance and fixes issues
Free, excellent for 3-axis CNC milling and routing. Candle: Clean, open-source interface for CNC milling. Step 3: Configure GRBL Settings
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)
Excellent, free, open-source software optimized specifically for laser cutting and engraving (Windows only).
