The board accepts a wide range of input voltages from . Ensure your power supply matches the voltage requirements of your stepper motors and laser module. Connect the positive (+) and negative (-) wires carefully to the main power screw terminals. Stepper Motor Drivers
Check your motor wiring sequence (A+, A-, B+, B- pairs). Alternatively, the stepper driver VREF current limit might be set too low. Gently turn the driver potentiometer clockwise to increase current, ensuring the motor gets enough power without overheating. Issue 3: Laser Stays On Constantly at 100% Power
Connect your 12V or 24V power supply to the DCIN screw terminal. Ensure correct polarity (+ and -). Reversing polarity can damage the board. 2. Stepper Motor Drivers & Motors

Located directly underneath each driver slot. Populating all three jumpers sets the driver to its maximum microstepping resolution (e.g., 1/16 for A4988, 1/32 for DRV8825). Limit Switches (Endstops) Dedicated 3-pin headers for X-MIN , Y-MIN , and Z-MIN .
The Makerbase MKS DLC v2.1 is a GRBL-compatible control board designed for desktop CNC and laser engraving, featuring ESP32-based processing for offline and Wi-Fi capabilities. Official technical documentation, including the schematic, pinout, and firmware, is available on the Makerbase MKS-DLC GitHub repository FluidNC on MakerBAse MKS DLC32 V2.1 The board accepts a wide range of input voltages from
Check if the TTL pin is connected correctly. Make sure you are using a 5V TTL signal.
Navigating documentation for maker hardware can sometimes feel like a scavenger hunt. To make your journey easier, here is a single reference table with all the essential resources.
The primary source for all documentation is Makerbase's official GitHub page. Before diving into the details, it's helpful to know that the main repository for the current-generation board is named rather than MKS-DLC (which houses info for the older 8-bit version). Stepper Motor Drivers Check your motor wiring sequence
Always verify 12V/24V jumper (labeled “JS1” on v2.1) — wrong setting .
Beneath each stepper driver slot are jumper pins. Insert jumpers to set your microstepping resolution (e.g., inserting all three jumpers sets an A4988 driver to 1/16 step or a DRV8825 to 1/32 step).
What you will find: Hardware schematics, board dimensions, pinout diagrams, and PDF manuals.
