xTool F1 always gives us impressive results when engrave on metal materials. But if you're not so professional with power settings, it might be a daunting task to get clear and detailed results in greyscale mode. So today, let's untangle this problem by using the power range adjustment function in XCS 1.3, which would help you to create detailed and precise engravings.

What is Power Range Used for？

    The grayscale algorithm works by accurately displaying subtle variations of gray in an image, based on the intensity of each pixel.

When engraving a grayscale bitmap image, the power level may not be sufficient to create a clear and detailed engraving. This can result in missed areas or incomplete lines in the engraved image (as in the image below).

    In XCS V1.3, the new power range function allows you to set and adjust the minimum power. When the minimum power is higher, you can obtain a crisper and a more detailed engraving result.

    The maximum power equals the power function in the previous version. When your engraved pattern is clear and completed, there's no need to adjust the minimum power.

Just a friendly reminder, if you're not using the "grayscale" mode, the algorithm is based on the dot to determine the engraving effect. That means there's no grayscale transition, and therefore no need to set a minimum power.

How to Adjust the Power Range?

The preset power range in XCS is from 1 to 10%. However, we recommend testing to determine the optimal minimum power for your specific material. 

Note that we will soon be releasing our officially recommended parameters for your reference, so please remember to check them out.

How to Conduct Your Own Test:

1. Open XCS and import the below grayscale testing image. Choose your material and select Grayscale mode.

2. Place the material to be processed (if you are using a darker material, you may need to use the "invert color" function first), and process the material with the recommended parameters.

3. After completion, check for any missed spots in the grayscale grids.

4. Adjust the minimum power, fine-tuning it until the engraving effect is clear and evident. (e.g. increase the minimum power to a gradient of 10%, 15%, 20%, etc.).
