F1, xTool's first galvo laser machine, varies significantly from previous semiconductor lasers in terms of machining parameter settings. For instance, we've incorporated a unique dot matrix algorithm in bitmap engraving, which offers superior results and efficiency.

This guide will explain the logic behind each parameter as well as how to set them respectively (Laser Type, Dot Duration, Power, Pass, DPI, Bitmap mode, and Engraving mode), aiding you in understanding and utilizing them to achieve optimal processing outcomes.

Laser type

F1 supports two types of laser light sources for processing: Blue light (10W) and IR (2W). The appropriate light source should be chosen based on the properties of the materials being used.

🔵 Blue light is typically used with materials like Tilia wood, corrugated paper, and leather, and for cutting processes.

🔴 IR light is ideal for engraving metals such as stainless steel, gold, silver, copper, aluminum, etc., .

Recommended parameters will provide suggestions for the light source most suitable for your selected material. For more advice on material and light source selection, please refer to the xTool Community 📚.

Dot duration

When processing bitmap, a complete image is formed by methodically doting each point. Hence the term "Dot Duration" refers to the time spent at each point, measured in microseconds (μs), and it affects the overall processing time. To ensure stable light output, especially for infrared lasers, we recommend setting more than 100μs. The optimal timing varies with the material but usually falls between 100 and 500. Please note that excessive dot duration could result in a whitening effect and a longer processing time.

Power

Power parameters range from 1 to 100%, influencing the depth of the engraving effect. For instance, higher power will result in deeper engravings on the material's surface, making darker materials appear whiter (shown in the image below ).

Pass

The default pass is 1 and supports up to 10 direct reprocessing times. The more passes, the deeper the engraving marks. Usually, after setting the parameters, you can get a better engraving effect at one time.

DPI (Dots Per Inch)

DPI is a unit of measurement in dot matrix digital image, indicating the number of image pixels per inch. The setting range is [1, 1270]. When converted into linear density (lines per cm), 100 linear density equals 254 DPI.

A higher DPI theoretically yields a finer engraving image effect. However, when the DPI surpasses the bitmap's pixel distribution, overly dense dots can have a counterproductive effect, causing darker materials to appear whiter (shows in the image below ).

Bitmap Mode

We offer seven image modes for selection, catering to most bitmap usage scenes. You can choose the algorithm type that best suits your image. Generally, we recommend Jarvis mode for infrared light and grayscale mode for blue light.

Engrave Mode

This can be divided into bi-directional or uni-directional scanning.

Bi-directional scanning is the default setting and is more efficient due to its shorter path, offering better processing efficiency. Uni-directional scanning can theoretically provide more detail as it does not require frequent changes in direction or complex corner paths.

In conclusion, understanding and effectively manipulating the settings on the F1 can make a significant difference in your engraving results. Take the time to experiment with different parameters and modes to discover what works best for your specific projects. Happy crafting! 🛠️
