Over extrusion at the bottom but not the 1st layer

Posted · Over extrusion at the bottom but not the 1st layer

Hi guys.

I just got my new ender3  V2. I am using cura version 4.6.2 and i have this weird problem.

The first 2 layers looks great. However, starting from the 3rd layer, it just over extruded.

 

I did some research online. Some said my print is too close to the print bed.

Then I raised up the 1st layer but still nothing changed.

 

Here are some photos of my test print.

One of the test print had a very bad adhesion as I raised up the 1st layer a lot.

The close up to the bottom shows that the first 2 layers are just fine.

 

Do you guys know why the extrusion is not stable??

I really need help from you guys.
