Manual focus gives you greater flexibility when using the Bolt Series, especially in non-standard engraving or cutting scenarios. With the included manual focus tool, you can quickly set the correct focus height and improve accuracy on uneven, warped, or pressure-sensitive materials.

This guide explains what the Bolt Series manual focus tool looks like, how to use it step by step, and when manual focus is a better choice than automatic focusing.

1. What Does the Manual Focus Tool Look Like?

The manual focus tool used with the Bolt Series has a simple T-shaped design. It comes with the Bolt Series and is designed to hook onto the laser head so you can check the correct focus distance quickly and accurately.

2. How to Use Manual Focus on the Bolt Series

Using the manual focus tool is quick and straightforward. Follow the steps below to place the tool correctly and adjust the Z-axis height.

2.1 Attach the Manual Focus Tool to the Laser Head

Take the manual focus tool and hook it onto the two set screws on the laser head. These two set screws are in the same position for all Bolt Series lenses, so you do not need to adjust the focus tool when switching between different lenses.

2.2 Adjust the Z-Axis Height

Adjust the Z-axis height while watching the manual focus tool. Focusing is complete when the bottom end of the focus tool just touches the surface of the material.

When using a rotary attachment, use a spirit level to confirm that the upper surface of the workpiece is level before focusing. This helps maintain consistent engraving results on cylindrical items.

3. When Should You Use Manual Focus?

Manual focus is especially useful when automatic focusing may not give the best result. It gives you direct control over the focus position and can be a reliable backup in several situations.

5. Conclusion

Manual focus is a practical and reliable focusing method for the Bolt Series. By placing the focus tool correctly, adjusting the Z-axis carefully, and checking the material surface before processing, you can set the correct focus height for a wide range of engraving and cutting tasks.

It is especially helpful for uneven materials, elastic materials, rotary work, or situations where the sensor needs a backup method. With a little patience during setup, manual focus can help you achieve cleaner and more consistent laser results.
