This is super important to prevent your laser from going outside of its working boundaries. Next, you'll want to set the origin of your laser. The origin determines where LightBurn considers the (0,0) point of your workspace.

• For the Sculpfun S9, the origin is typically at the front-left corner. Make sure this is correctly configured in LightBurn's settings. Once your device is set up, you'll need to configure your settings, which is essential to achieve good results. Let's delve into those settings! LightBurn is a powerful software, and these settings are essential to start your projects. Pay close attention to these steps, as they are crucial for setting up your Sculpfun S9 in LightBurn correctly. Make sure that you have connected all the power cables to make sure the machine starts successfully. Don't worry, the setup is pretty easy, and once you get it, you will be creating many projects.

Sculpfun S9 LightBurn Settings: Speed, Power, and Focus

Now, let's get into the Sculpfun S9 LightBurn settings that will make or break your engravings. The most important parameters to get right are speed, power, and focus. These three work in concert to determine how the laser interacts with your material. Let's explore each one in detail, and how to calibrate it.

• Speed: Speed refers to how fast your laser head moves across the material. It's measured in millimeters per minute (mm/min) or millimeters per second (mm/s). The ideal speed varies greatly depending on the material, power, and desired outcome.
  • For example, when engraving wood, a slower speed (e.g., 1000-2000 mm/min) combined with higher power will result in deeper, darker engravings. This is especially true for projects like creating intricate designs.
  • On the other hand, for engraving photos on wood, you might want to use a faster speed (e.g., 2500-4000 mm/min) with lower power to get a more subtle, grayscale effect. Experimentation is key to find the optimal speed for each material and project. Start with some test engravings, and adjust the speed in small increments. Remember that slower speeds generally result in deeper engravings, while faster speeds produce lighter marks.
• Power: Power refers to the intensity of the laser beam. It's usually expressed as a percentage (0-100%). The power setting determines how much energy the laser puts out.
  • Higher power settings are suitable for cutting thicker materials or achieving deeper engravings. For cutting, you'll need to dial up the power. Make sure you adjust the speed appropriately.
  • Lower power settings are perfect for finer details, lighter marks, or engraving delicate materials. When working with materials like acrylic or engraving photos, you'll want to carefully manage the power setting to avoid burning or melting the material. Always start with low power and gradually increase it until you get the desired result. Be mindful of the material. Different types of wood react differently to the laser, so the ideal power will change.
• Focus: Focus is the most critical setting. The focus refers to the distance between the laser lens and the material's surface. A properly focused laser beam will produce the cleanest, most efficient cuts and engravings.
  • The Sculpfun S9 typically has a fixed focal length, meaning there's a specific distance the laser head needs to be from the material. You can determine the correct focus distance with the help of the included focus gauge.
  • Place the material on the bed and lower the laser head until the bottom of the laser head touches the focus gauge.
  • Then, move the laser head up until the gauge fits between the lens and the material. Double-check your focus before each project. This ensures optimal results.

Experimenting with these three settings is crucial. Make sure you make small adjustments and run test engravings to see how your material reacts. Keep records of your settings to replicate your success. These three parameters are the foundation of successful laser engraving.

Material-Specific Settings for Your Sculpfun S9

One of the most exciting aspects of laser engraving is working with a wide range of materials. However, each material requires slightly different settings to get the best results. Here are some general guidelines for the most common materials that you're likely to work with using your Sculpfun S9 and LightBurn. Remember that these are starting points, and you'll want to fine-tune them based on the specific material you're using.

• Wood: Wood is a classic material for laser engraving. The settings will vary depending on the type of wood and the desired effect.

  • For engraving: Start with a speed of 1000-2000 mm/min and a power setting of 40-70%. You can go slower and with more power for a deeper engraving.
  • For cutting: Set the speed to 500-1000 mm/min and use a power setting of 80-100%. You'll likely need multiple passes, especially for thicker wood. Different types of wood, such as hardwoods and softwoods, will require different power and speed settings. Always start with tests on a scrap piece.

• Acrylic: Acrylic is another popular material, especially for signs, and decorations.

  • For engraving: Use a speed of 2500-4000 mm/min and a power setting of 20-40%. You'll need to be careful to avoid melting the acrylic.
  • For cutting: Use a speed of 100-500 mm/min and a power setting of 70-90%. Acrylic can be tricky to cut, so make sure your focus is precise. The type of acrylic (e.g., cast or extruded) can also influence the settings. Always test before you start on your main piece.

• Cardboard: Cardboard is great for making templates and prototypes.

  • For engraving: Use a speed of 2500-4000 mm/min and a power setting of 30-50%. It's easy to achieve detailed engravings with cardboard.
  • For cutting: Set the speed to 100-500 mm/min and a power setting of 70-100%. Cardboard will cut quickly, but the quality will depend on the cardboard's thickness and composition. Multiple passes may be necessary.
