Hello all!

It is my first post, I am newie on the 3d printing world and I have an Ender 3 since one week ago.

Setting of the printer has not been hard and I am very happy with the result in general. However all my models show a rare and rough strip just above the first layer, once the nozzle leave that height, the quality of surface is as expected with a nice and flat texture.

I am printing with PLA and using Cura 4.8. I have touched many parameters on Cura, temperature, velocity, layer thick, etc, etc, but I am still getting that ugly issue.

I show here an image with the issue highlighted in red arrows.

I hope someone can help me with this and point me in the right direction.

Thanks in advance, greattings from Chile.

Repo.
