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

Use the TTL/PWM port (usually 3-pin or 2-pin) to control laser intensity.

The DLC v2.1 is an "all-in-one" board designed to run GRBL. It supports 3-axis control (X, Y, and Z) and features specific ports for laser TTL control and CNC spindles. Key Specifications ATMega328P (8-bit) Input Voltage: 12V to 24V DC Supported Drivers: A4988, DRV8825, TMC2208, TMC2209 Interface: USB for PC connection 🔌 Setup and Wiring Guide

Professional-grade paid software for laser cutting.

Use the Spindle relay or PWM output to control your motor tool. 💻 Software Configuration

Once connected via USB (usually at ), you may need to adjust these settings in the console: $100, $101, $102 : Steps per mm for X, Y, and Z. $32=1 : Enable Laser Mode (if using a laser).

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

Check your Vref on the stepper drivers; they might not be getting enough current.
