Second + layer issues


Any idea?first layer perfect, my second + layers have bad finish, i did all the calibrations ( + flow calibration and pressure) and still same issue , bambu basic black pla

It doing that when it get towards center

Door close

Rise mod

Using ams

Second + layer was 200 speed but dropping down to silent mode didn’t make much difference, .4 nozzle , .08 layer hight

Flow rate .98 pressure .015

could you give a little more detail on this? or maybe a second image from a different angle?

This looks very strange, almost as if you have some kind of pattern.

All sorted it,ive only did that self check or something

Ive run it with white filament and it was perfect then with same black one as before and same it end up perfect , I’m a bit confused about that but it works so I’m happy

i’m having the same problem mate with layer 2 , can you help me out

 thanks

Just go to you bambu handy app and go to machine assistant and choose that self check option, and try again , that what i did end of the day and it works since
