<p>After I switched to the 0.6&nbsp;mm Nozzle I have massive problems to get good results, as you can see in the picture below. The two parts in the front starting to have from the height of about 5&nbsp;mm very bad lines. I realized it 5&nbsp;mm later and I set manually the temperature from 215 to 220&nbsp;&deg;C which seemed to solved the problem a little bit, but still not perfect results.</p>

<p>As you can see in the second picture, I removed the 0.6&nbsp;mm nozzle to make sure it fitted. I did, there is no filament on the thread.</p>

<p>Test: I did use some noname filament with the 0.6&nbsp;mm nozzle first and had bad results as well. The problem mainly was, that the temperature (215&nbsp;&deg;C) was too low. So I raised it for the noname filament to 240&nbsp;&deg; which seemed to solve the problem but quality was not perfect, so I switched to the Prusa Polymers filament to make sure the issue is not related to the filament.</p>

<p>So what could be the issue here?</p>

There are strong indicators that the problem is related to the flow rate setting.
