Operating LP4 with LightBurn

  • Updated

In this guide, you will learn how to set up the LightBurn software and use it to operate the LaserPecker 4 (LP4).


LightBurn is a third-party software. Shenzhen Hingin Technology Co., Ltd. (AKA: LaserPecker) does not assume any responsibility for the loss of any data (designs, projects, etc.) caused by using LightBurn.

Although the LP4's firmware has undergone comprehensive testing, software or hardware incompatibility may still occur in some cases. For errors caused by incompatibility, you can contact our after-sales services via support@laserpecker.com for technical support and potential solutions.

1. LightBurn - Software Downloading and Installation

  1. To operate the LP4 using LightBurn, you must first go to the official website and follow the download and installation instructions. The full version of LightBurn is available for a free 30-day trial.
  2. A user's license is required to continue using LightBurn after your free 30-day trial period has ended. At the end of the trial period, you will be prompted to input a key code to continue using the software.
  3. To purchase a license and receive a key code, go to the LightBurn Online Store and select the "GCode License Key". Make sure you only purchase the GCode License Kaey, as it is the only version that is compatible with the LP4.
  4. After purchasing your license, you will receive an email from LightBurn containing the key code and activation instructions.


The latest version of LightBurn and the GCode License Key are essential, so opting for anything else will not work. If you happen to purchase the wrong software mistakenly, you will need to resolve the issue with LightBurn directly.

2. Download and Import the LP4 Configuration Packages

  1. After installation is completed, open LightBurn and input your GCode License Key. (after the trial period, LightBurn cannot be used without a purchased license).
  2. Before using LightBurn with your LP4 for the first time, you will need to import the appropriate lbdev configuration files. Click here to download configuration packages
  3. When opening LightBurn for the first time you will be asked to import a configuration file. A pop-up window will appear prompting you to import the lbdev configuration file. Click "Import" to locate the downloaded configuration file.

3. Operating the LP4 with LightBurn

3.1 Connecting the LP4 to a Desktop PC

  • Quit the LaserPecker Design Space (LDS) Software before continuing and if the LDS App is installed on a nearby mobile device, it should not be active while attempting to connect the LP4 to LightBurn.
  • Connect the desktop PC and LP4 using a USB-C to USB-A cable. Insert the USB-C end into the LP4 and the USB-A end into the desktop PC.

Make sure to use a USB-A to USB-C cable. Using a USB-C to USB-C cable may result in an ineffective connection. If needed, a USB-A to USB-C adapter can be used.

connect your computer to LaserPecker 4

The USB serial port needs to be selected to establish a connection with LightBurn. After plugging in the USB cable, the software will recognize the COM in "Devices". Select the port from the drop-down menu to start the connection.

connect your computer to LaserPecker 4

If it is not recognized or incorrectly connected, please check if the USB cable and USB socket are faulty.

3.2 Switching Laser Types

Click the "Settings" tab in the LightBurn toolbar and locate the "Better for diode" option in the center of the pop-up window. Select your preferred unit of measurement and click "OK" to complete the setup process.

3.4 Focusing

This version of the LP4 LightBurn configuration package doesn't have a built-in command for Dual Red Light Focusing. To set the correct focal distance, please use either the Manual Method or the Safety Shield Method as described below.

A Dual Red Light Focusing command will be added to the next versions of the LP4 LightBurn configuration package and LP4 firmware. Stay tuned for release information.

Manual Focusing Method

Using the supplied ruler, adjust the height of the Laser Unit so that the distance between the lens and the top of the material is 15 cm.

manual focusing method

When measuring, please make sure to use the bottom rim of the lens and avoid touching the lens itself at all times.

Safety Shield Focusing Method

Raise the Laser Unit to at least 20 cm from the Base Plate. Align the magnetic Safety Shield under the Laser Unit and attach it in place around the laser lens. Connect the Exhaust Fan cable to the rear of the Laser Unit.

Place the material to be worked with onto the Base Plate in the proper orientation and lower the Electric Stand. The laser will be in focus when the bottom of the Safety Shield is at the very top of the material.
