GRBL Guide

Software Download Process
Laser GRBL stands as a prominent DIY laser engraving software. You can acquire it from the Laser GRBL website: http://lasergrbl.com/download/ (Alternatively, the manufacturer may provide the installation package on the TF card or a USB flash disk).
Laser GRBL is user-friendly; however, it exclusively supports the Windows operating system (Win XP/Win 7/Win 8/XP/Win 10). For Mac users, the option of Light Burn exists, an impressive engraving software albeit not free. It is worth noting that Light Burn also extends its compatibility to the Windows system.
Note: During the engraving process, the engraving machine must maintain a connection with the computer, and the engraving machine’s software should not be turned off.

Software Installation
Initiate the software installation by double-clicking the software installation package. Follow the “Next” prompts until the installation procedure is finalized.

Language Selection
Navigate to the top menu and choose “Language” to designate your preferred language.

Loading an Engraving File
Sequentially click on “File” and “Open File,” as illustrated in figure 8.1. Subsequently, choose the image you intend to engrave. LaserGRBL accommodates file formats such as NC, BMP, JPG, and PNG.

Adjusting Picture Parameter, Engraving Mode and Engraving Quality

1. Laser GRBL empowers the adjustment of attributes like sharpness, brightness, contrast, and highlights for the selected image. During this adjustment, a preview window displays the effects, allowing you to fine-tune them to your preference.

2. When selecting the engraving mode, options typically include “Line-to-line Tracking” and “1Bit Shaking.” “1Bit Shaking” is particularly suited for engraving grayscale images. For cutting purposes, opt for “Vector Diagram” or “Center Line.”

3. Engraving quality pertains to the laser scanning’s line width. This parameter hinges on the engraving machine’s laser spot size.
   Note: The recommended range for engraving quality is between 12 and 15. Diverse materials react differently to laser exposure, hence the specific value relies on the exact engraving material.

4. At the lower part of the preview window, features such as rotation, mirroring, and cutting of the image are available. Once the aforementioned settings are in place, proceed to the next step to configure engraving speed, energy, and size.

Configuring Engraving Parameters: Speed, Energy, and Size

1. The recommended engraving speed stands at 1000, a value refined through repeated experimentation. Naturally, you can adjust this speed higher or lower based on your preference. Opting for a faster speed will save time but might compromise the engraving quality, while a slower speed yields the opposite effect.
2. In the laser mode, two instructions are available: M3 and M4. For “bit jitter” mode engraving, it’s advisable to use the M4 instruction, while the M3 instruction suits other scenarios. If your laser supports only M3, verify whether the laser mode is configured in GRBL settings. For detailed guidance on GRBL configuration, refer to Laser GRBL’s official instructions.
3. Selection of engraving energy should align with the specific material being used.
4. To finalize, adjust the size parameter and then activate the process by clicking the “Create” button, completing the setup for all engraving parameters.

Saving the GCODE File
Access the top menu of the software interface and click “File.” From the dropdown menu, choose “Save.” Afterwards, transfer the saved .nc file onto the TF card. Insert the TF card into the engraver to employ the file for your engraving task.
For the addition of preview codes to G code files, employ the “MKS Laser Tool” software within the TF card.

Computer Connection

1. Establishing Connection

• Connect the machine to a computer equipped with the Laser GRBL software using a USB data cable.
• Power on the machine.
• Launch Laser GRBL on the computer.

2. Configuration Steps

• Choose the specific port number and set the baud rate to 115200 (Refer to Figure A.10).
• Click on the lightning icon. Successful connection is indicated when the lightning icon changes to a red “X,” and the directional indicator is illuminated (See Figure A.11).

Typically, manual selection of the COM port isn’t necessary. This is unless multiple serial port devices are linked to the computer. If needed, locate the machine’s port in the device manager of the Windows system (as depicted in Figure A.09). Alternatively, you can simply try the displayed port numbers one by one to establish connection.

Troubleshooting Port Detection Issues
If you’re unable to locate the appropriate port under “Ports,” you might need to try the following methods:
Method 1: Click on “Tools” in the menu to install the CH340 driver (Note: This option might not be available in certain software versions).
Method 2: Copy the “CH340ser.exe” file from the TF Card (USB flash disk) to your computer and proceed with installation.

Important Instructions for Laser Head Maintenance and Lens Cleaning

1. After a period of laser head usage, it’s important to clean the lens positioned below the laser head’s light outlet. This maintenance ensures consistent cutting performance.
2. Lens cleaning should only be performed when the machine is powered off to avoid laser related risks.
3. Post-lens cleaning, allow the lens to air-dry naturally for approximately 3-5 minutes before powering on. This precaution prevents potential lens breakage due to residual moisture upon activation.
4. For further guidance, scan the QR code in the manual to access video tutorials.

Materials Reference

Cutting

Important Note:

• When the energy value is set to 500, the laser intensity corresponds to 50% of the total power.
• Setting the energy value to 1000 establishes a laser intensity-to-power proportion of 100%. Higher energy values permit increased speed settings.
• The provided parameters serve as reference points. Material characteristics may vary; thus, it’s advised to adapt parameter values based on specific conditions.

Initial Machine Testing and Safety Precautions

1. Initial Setup and Connection
   • Power on the machine and establish a connection with the computer.

2. Movement Verification
   • Perform a movement test: Utilize the software to control the machine’s upward, downward, leftward, and rightward motions.
   • Confirm the correct movement directions (Refer to Figure A01) and validate accurate movement distances (See Figure A02).

3. Laser Emission Check
   • Test laser emission: Import a custom icon into the software and activate the light function (low intensity).
   • Wear protective eyewear to observe whether the laser module emits blue light (Refer to Figure A03).

4. TF Card File Testing
   • Caution: Laser emissions can generate heat and glare, posing potential harm. Adhere to instructions carefully to avoid injury.

Z-Axis Automated Focusing Mechanism
The automated focusing mechanism ensures optimal engraving precision through a series of coordinated movements.

Operational Explanation:

• The laser module lifter initiates a downward movement.
• Upon the probe touching the engraving surface, the Z-axis limit switch activates.
• In response, the laser module elevates to the pre-defined lifting height.
• Software settings dictate the lifting height, thereby allowing the machine to autonomously complete the focusing process.

Precision Achieved:

• Elevating the laser module by 7mm (configured lifting height of 7mm) establishes a focal length of 50mm. This carefully controlled focal distance guarantees precise and consistent engraving results.

LaserGRBL Software

• Accurate Serial Number and Baud Rate (115200) Selection and Establishment of Connection

Notes: The fixed engraving height of 7 mm serves as a baseline parameter. If the object to be cut is 4 mm thick, the laser head’s focal length needs to account for half of the object’s thickness. To adjust for this, input “7 (engraving height) – 2 (object center position) = 5 mm” and input “$42=5” for cutting parameters. Similarly, you can set various cutting parameters for different material thicknesses.
