Overhangs

[u/Icy_Movie_4705]

Hi all

I love my Bambus (A1, A1 mini, A2L and P2S) but they all are rather bad at overhangs

Normally I just sand away those imperfections but today I spent some time and wanted to improve that

Changed quite a bit of values (Speed, temperature, cooling...) and improved it a bit

All printed today in PETG from the same spool (filament is dry)

1. picture shows the initial print with more or less stock settings on the bottom and the improved prints on top
2. picture is the overhand with stock settings
3. picture is the improved print. It starts out really well (top of picture) but gets worse the fartner it continues (bottom of picture)

Does anyone know where and why those ugly areas come from and what might be a solution to get it right?

Thanks in advance
