like this:
 

But it shows a very round image on my image. I am using an incremental encoder.
like this:
 

Can anyone explain me the reason? I think it’s a problem with the drawing algorithm

Go to "acceleration", input your numbers and you will see that the acceleration is way to slow for the feed rate you are requesting.

Sorry, my question is "Why is the circle interpolated by the laser an ellipse but the circle shown in the image is a perfect circle?"

Acceleration to slow for the requested feedrate.
Use
G64 P0.1
Or set higher accelerations in the .ini file.
