4. Setup
The Monport 100W Fiber Laser Engraver is designed for quick and straightforward setup. The foldable vertical arm simplifies initial assembly.
4.1 Initial Assembly
- Carefully remove all components from the packaging.
- Place the main unit on a stable, level surface.
- Unfold the vertical arm into its upright position.
- Secure the vertical arm by tightening the two designated screws using the provided wrench. Ensure the arm is firmly fixed to prevent movement during operation.
- Connect the power line to the machine and a suitable power outlet.
- Connect the USB data cable from the machine to your computer.
4.2 Software Installation
Insert the provided U Disk into your computer. Install the necessary drivers and software (BSL App or LightBurn) as instructed on the disk. Refer to the software-specific documentation for detailed installation and configuration steps.
5. Operating Instructions
This section outlines the general steps for operating your laser engraver. Detailed operational procedures will be found within the specific software documentation (LightBurn or BSL App).
5.1 Power On and Connection
- Ensure all cables are securely connected.
- Turn on the main power switch on the laser engraver.
- Launch your chosen laser control software (LightBurn or BSL App) on your computer.
- Verify that the software recognizes and connects to the laser engraver.
5.2 Material Placement and Focusing
- Place the material to be marked on the work platform.
- Utilize the autofocus feature or manual focus to set the correct focal distance (refer to Section 5.3).
5.3 Autofocus Feature
The Monport 100W Fiber Laser Engraver features proprietary autofocus technology for precise and efficient focusing. This system uses three red lights for guidance and achieves high precision with an error of less than ±1mm.
- Ensure the material is positioned correctly under the laser head.
- Press the dedicated autofocus button on the machine or activate it through the software interface.
- The laser head will automatically adjust its height until optimal focus is achieved.
- For manual focusing, adjust the vertical arm until the three red dot guides converge into a single point on the material surface.

5.4 Vertical Arm Rotation
The vertical arm of the engraver offers an adjustable range of ±90° for increased versatility in marking applications.
- To adjust the arm angle, slightly loosen the screws securing the arm.
- Carefully rotate the arm to the desired angle within the ±90° range.
- Once the desired angle is set, re-tighten the screws to secure the arm in position.
5.5 Design and Engraving
- Create or import your design within the LightBurn or BSL App software.
- Configure laser parameters such as power, speed, frequency, and pulse width according to the material and desired effect.
- Perform a test mark on a scrap piece of the same material to verify settings.
- Initiate the engraving process from the software. Monitor the operation closely.
6. Software Compatibility
The Monport 100W Fiber Laser Engraver is compatible with industry-standard laser control software.
- LightBurn: A powerful and widely used laser control software (paid license required).
- BSL App: Monport's free proprietary software.
Both software options allow for design editing, arrangement, and control of the laser marking process. Refer to the respective software documentation for detailed usage instructions.
