DIY 3018 Small CNC USB Motion Control Board + 3 Motor Drivers (SKU#3D1016)

This USB Motion Control Board is a replacement spare part specifically designed for small desktop CNC machines like the DIY CNC 3018 series. It serves as the main controller for stepper motors, spindle, and coordinate motion, enabling precise and stable operation via USB connection.

Key Features:

• Compatible with DIY CNC 3018 and similar 3-axis machines (X, Y, Z)
• ARM 32-bit processor architecture for higher precision and speed
• GRBL 1.1F firmware pre-installed (not customizable or modifiable)
• Integrated A4988 stepper motor drivers (supports NEMA17 or similar motors)
• USB interface for direct PC connection (Windows supported)
• Controls both spindle and laser modules (PWM/TTL control)
• Supports popular CNC software: LaserGRBL, LightBurn, Candle, UGS, General Gcode Sender
• Plug-and-play design for easy replacement or integration
• LED indicators for power and operating status (red = power, green = active/running)

Applications:

• Replacement part for DIY CNC 3018 machines
• Custom desktop CNC machine projects
• CNC milling, engraving, and cutting
• Laser engraving with compatible modules
• Educational and prototyping CNC setups

Precautions

• Ensure wiring sequence matches before connecting the control board to avoid damage.
• Do not connect the offline controller and computer data cable at the same time — this may cause a communication conflict.
• This is not a development board; firmware cannot be customized or modified.

Troubleshooting Tips

• Machine moves inaccurately: Recalibrate stepper motor, limit switches, and acceleration settings.
• Stepper motor noise: Adjust current settings on the stepper motor driver.
• No connection to PC: Check USB/COM port settings and ensure the driver is correctly installed.
• LED indicators: Red = power connected, Green = operational status.
