<p>I've asked a question before on the extruder gear clicking on my CR-10, but I'm certain its because of the nozzle getting clogged for some reason. I'm using a standard 0.4&nbsp;mm nozzle with white PLA and randomly during the print the extruder gear starts clicking on the fast parts and then under extrudes the rest of the print, eventually the hobbed gear digs away at the filament and doesn't grip anymore. Why would the nozzle keep getting clogged? Could it be because the filament isn't high enough quality and is leaving particles in the nozzle? </p>

<p>Additionally, when I performed a cold pull after breaking up the blockage on the inside, the filament came out like a thin film even though it was purging fine before I cooled it down. Why?</p>

<ul>
<li>190&nbsp;&deg;C nozzle temperature (tried printing at 210&nbsp;&deg;C and the filament burned)</li>
<li>50&nbsp;&deg;C bed temperature</li>
<li>60&nbsp;mm/s speed, outline 50&nbsp;% - first layer being 30&nbsp;mm/s</li>
<li>0.2&nbsp;mm layer height</li>
</ul>

<p>This starting happening after I returned to printing after a 6 month break, with the filament being stored in a cool and dry cupboard for around a year (the filament was on the cheaper side, but still highly recommended by SUNLU)</p>
