This guide explains how to manually measure and set the focus distance for more accurate engraving and cutting.
When to Use Manual Focus?
- The camera cannot accurately detect the material height
- Processing irregular or thick materials
- More precise focus adjustment is required
Note
Manual focus does not support Curved Surface mode; it only supports Base Plate mode, Rotary Extension mode, and Conveyor Feeder mode.
Before You Begin: Reset the Z-Axis Position
Before manually focusing, make sure the Z-axis has been reset to its default position. You can reset the Z-axis position by following one of the steps below:
(1) Refresh the camera background to reset the Z-axis automatically.
(2) Use the "Go to Origin" feature.
Measure and Enter the Focusing Distance
(1) Move the Laser Module above the material to be processed and use a ruler or caliper to measure the vertical distance from the material surface to the bottom edge of the laser module, as shown in the image below.
(2) Enter the value into the "Distance" parameter bar in the top right corner.
Note
If the measured distance is smaller than 22 mm, the material may be too thick for the laser module to achieve proper focus. In this case, you may need to install the Riser Base to achieve proper focus.
(3) Process the material and check whether the engraving result is sharp and clear.
A correctly focused result should have sharp edges, clear details, and consistent engraving quality.
If the result is unclear, slightly adjust the distance and test again until the engraving appears sharp and consistent.
