<p>I'm printing a cylindrical piece but at any moment it breaks down. I tried it two times, both have break down in different place. I'm using a 1.75&nbsp;mm PLA filament in my Anet A8. I'm using Cura 2.6.2 to export to a <code>.gcode</code> file.</p>

<p>This is the original model: </p>

<p>And this is the result:</p>

But if you print something big or unique it\'s not cost effective. Slowing down the complete print is also not very time efficient. </p>\n\n<p>In Cura there an option called <strong>Mininum layer time</strong>, which addresses this problem:</p>\n\n<pre><code>Cooling -&gt; Minimum Layer Time / Minimum Speed\n</code></pre>\n\n<p>This means that it will only slow down when the print distance for a particular layer is short. Giving the material some extra time to harden. Other layers will be printed at normal speed. Increased print time will be limited this way. </p>\n\n<p>For your situation I would advise you to increase the part cooling, if possible, in conjunction with configuring the <em>Minimum Layer Time</em> option mentioned above.</p>\n'}]
