<p>It seems there are some missing lines on the outer wall on the Z-axis with my prints. I'm not able to pinpoint the problem. Does anyone have ideas about what might be wrong with my setup/settings?</p>
<p>Example:</p>
<p><a href="https://i.stack.imgur.com/3q1k3.jpg" rel="nofollow noreferrer" title="Printed model with printing errors highlighted"><img src="https://i.stack.imgur.com/3q1k3.jpg" alt="Printed model with printing errors highlighted" title="Printed model with printing errors highlighted" /></a></p>
<p>Here are some settings that I think are relevant:<br />
Printer: Ender 3 v1<br />
Filament: Das Filament<br />
Slicer: Cura</p>
<ul>
<li>Hotend temp: 215 °C</li>
<li>Layer height: 0.2 mm</li>
<li>Wall speed: 30 mm/s</li>
<li>Travel speed: 200 mm/s</li>
<li>Retraction distance: 6.5 mm</li>
<li>Combing mode: not in skin (Max comb: 30)</li>
</ul>
<p>Cheers</p>
