2nd layer larger than others

[vision3D 0]

Hello,

 

My print had elephant foot and I tried to figure it out.

It seems the root cause is the generated gcode, when I open it with Cura the second layer is obviously larger than others.

I'm using the default parameters for ender 3 pro printer, the following should affect only the first layer if Im right.

Initial Layer Line width : 100%
Initial Layer Horizontal Expansion :  0
Initial Layer Flow :  100%

 

I tried 2 differents stl files https://www.thingiverse.com/thing:1278865 or https://www.youmagine.com/designs/10mm-cube and two Cura version 4.7.0 and 4.6.2.

 

Any thoughts would be appreciated.
