How to improve engraving quality in the scan mode of X-swing

The engraving quality working on x_swing is generally worse than x_unilateralism, it usually results in ghosting effect or image offset or bi-directional engraving offset, like below.   

  

Notice : We generally use plywood or acrylic to test.

 

x_swing function in different software:

RDWorks:


Lightburn:

 

How to improve engraving quality?

In RDWorks and Lightburn, you can adjust the Reverse compensation to improve this issue.

 

RDWorks: 

1.Open the test file

Click the link below for the test file:

RDWorks-Scan offset testing 

Note:If the file cannot be opened, please contact us.

 

You only need to test and adjust for above five speeds:200mm/s, 400mm/s, 600mm/s, 800mm/s, 1000mm/s , then other speed from 1mm/s to 1000mm/s will be calibrate automatically.

Note:The power used for the test is as follows. (Take 80W as an example)

       

 

 2. Test and calibrate the Reverse compensation

Open System Setting window: Config >> System Setting >> Optimize, like below.

This is the reference value of the reverse compensation of a Nova35. 


3. Test and calibrate

Send the file to your laser machine and test, then adjust the values of reverse compensation according to the results for each speed, like below.

Note: Each time you change the value of reverse compensation, please send again the test file to your machine and test.



Look at the results with a magnifying glass and calibrate reverse compensation until the lines will align horizontally, like below.


Note: During the calibration process, each adjustment is approximately between 0.05 and 0.1.

The following is a comparison chart when adjusting 400mm/s.


Reverse Compensation: 0.33                 Reverse Compensation: 0.38

 

Reverse Compensation: 0.43

 

Lightburn:

1. You can download the scan offset test file for testing.
