<p>I am trying to print a <a href="https://www.thingiverse.com/thing:2755765" rel="nofollow noreferrer">12 hole Ocarina</a> I found on thingiverse. When printing I have to stop it around 25-30 layers because the edge of the shell is higher then the infill. </p>

<p><a href="https://i.stack.imgur.com/PVHAO.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PVHAO.jpg" alt="Example 2"></a></p>

<p><a href="https://www.codepile.net/pile/Z0Y3v986" rel="nofollow noreferrer">G-Code of first 30 layers</a></p>

<p>I tried changing the infill, wall size, speed and retraction settings to no avail. The settings of the example print were:</p>

<ul>
<li>100% infill</li>
<li>0.2mm layer height</li>
<li>40mm printing speed (average)</li>
<li>1mm shell thickness (results in 2 layers)</li>
<li>Automatic infill patern</li>
<li>Printed at 210C with 3mm PLA (<a href="https://www.conrad.nl/p/renkforce-pla300h1-filament-pla-kunststof-3-mm-grijs-1-kg-1093147" rel="nofollow noreferrer">like this one</a>)</li>
<li>Printed on a RF1000</li>
<li>Sliced with CuraEngine in Repetier-host V2.1.6.</li>
</ul>

<p>Does anyone know what might cause this and how I can prevent it from happening?</p>

<p>Any help is greatly appreciated! :)</p>

Ever since then I\'ve been leveling the bed this way, not realizing I was preventing the head from reaching end-of-rail without having to force against the bed.</p>\n\n<p>So yeah, just took the bed as far down as possible, made the printer auto-home and leveled the bed from there, as it should be done, and my print is now going very well.</p>\n'}]
