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.

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.
