4-2 Machine Settings

Description

This article explains how to identify the machine's field lens model and adjust its parameter settings to ensure proper operation.

Step 1 - Confirm the Field Lens Model

⚠︎ Models above 60W must use a fused silica field lens to prevent damage.

Refer to the data above and compare it with the numbers shown in the photo below to confirm the field lens model installed in your machine.

Step 2 - Check the Focal Length and Work Area Size

In the example below, the lens model is JG-SL-1064-330-220B-10, and its focal length should be 343 mm.

Check whether the work area size in the document settings matches the information provided above.

First use the focal length above, then use the filled square to perform an engraving test. Move the field lens up and down during engraving to find the position where the engraving sparks are strongest and obtain the correct focal length.

Step 3 - Check the Red Dots

After confirming the distance, the two red dots should overlap. If they do not overlap, adjust the red dot positions so that they merge into one dot.

⚠︎ Note: Desktop fiber laser machines (MOPA does not) have an additional larger red dot. Make sure that it does not overlap with the two smaller red dots used to confirm the focus.

If the two red dots on your machine are not aligned, loosen one screw on the red dot emitter and adjust the red dot position so that the dots overlap. Then retighten the screw to secure the red dot emitter. Adjustment tips:

When aligning the two red dots, it is recommended to position the movable red dot slightly to the lower left of the fixed red dot.
Take into account the slight displacement that may occur when tightening the securing screw.
If necessary, gently tap the red dot emitter with a tool to ensure that the two dots are perfectly aligned.

Step 4 - Check the Machine Settings

Select Machine Settings from the Beam Studio toolbar. The path is “Machine >  Promark (your machine name) > Machine Settings.” Confirm that the parameters are the same as those on your QC Pass Card.

Step 5 - Mark the Work Area

After confirming that the parameters match the QC Pass Card, click the “Mark” button to draw the work area.

Step 6 - Check the Engraving Result

Make sure that all four corners of the work area engraving result are complete and have no defects (the upper-left corner in the image has a missing section).

Step 6-1 - Adjust the Area Settings

(If all four marked corners are complete and free of defects, you can skip this step.)

If there are defects in the corners, you must adjust the parameter values.

Refer to the adjustment sequence information below to make changes.

This section requires adjustment of the “Area”

Refer to the following information to reset the parameters.

Example:

Based on this result, the upper-left corner has a defect.
The work area should be moved slightly toward the lower right. This means that the “X Offset” value needs to be decreased, while the “Y Offset” value needs to be increased.

Step 7 - Check the Shape of the Work Area Engraving

If the shape of the engraved work area is distorted, refer to the following information for adjustment.
ⓘ The distortion parameter will not change significantly when the value exceeds 0.8~1.2. Adjust within this range to find the most suitable parameter.

Step 8 - Check the Preview Function
 

After engraving the correct work area size, click Preview to confirm whether the red light frame is aligned with the engraving outline.

Step 8-1 - Adjust the Preview Offset

If the red light frame is offset from the engraving result, as shown in the example below, refer to the following method for adjustment.

Example:
Based on the result above, the preview image is slightly shifted toward the lower right.
This means that the “X Offset” value needs to be increased while the “Y Offset” value needs to be decreased.

Step 9 - Verify the Adjustment Results

Create and engrave a square in Beam Studio, then activate the preview red light to ensure that the red frame aligns with the engraving outline.
