<p>Why does this happen (circled in red), and how can I fix it? It is making my prints come out horrible.</p>

<p>Not shown in the picture, but the option "Coasting" was Enabled:</p>

<ul>
<li>Coasting Volume 0.064 mm<sup>3</sup></li>
<li>Minimum Volume Before Coasting: 0.8</li>
<li>Coasting Speed 90%</li>
</ul>
