Use the TTL/PWM port (usually 3-pin or 2-pin) to control laser intensity.
The primary source for all documentation, wiring diagrams, and firmware for the MKS DLC v2.1 is the official Makerbase GitHub repository. Makerbase MKS DLC GitHub
Check if your $32 setting is correct and ensure the TTL wire is on the correct pin.

Insert your stepper drivers into the slots for the X, Y, and Z axes.
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 Use the TTL/PWM port (usually 3-pin or 2-pin)
Ensure the "Enable" pin on the driver matches the "EN" pin on the board.
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 If you need more specific help, I can
