Hi!
Im relatively new to 3d printing world and i would need a bit of help.
I have an ender 3 Pro, and from time to time, my nozzle gets clogged.
For each print, the first layer is printed without any issue, but for the next layers, it starts to print the layer properly but at some point my nozzle starts to make that horrible noise that indicates that is clogged

I have seen that the layer is not flat, it is, it prints a bit of the layer, and it starts to print again on top of it, so my feeling is that the z axis is not going up as much as it should and hence the nozzle gets blocked.

Any idea on how could i solve this?
Thanks
