<p>I tried printing something after 7 weeks of not using the printer (before it worked greatly) and I think it doesn't extrude properly (although I'm not sure about it).</p>
<p>When I tell the printer to extrude filament it works just fine, but during the print there seems to be a problem with it (see image below). When manually pushing the filament with some force, it works for a bit, but stops working after 1 minute.</p>
<p>I tried cleaning the gear, levelling and cleaning the bed with almost no success.</p>
<p>I'm using a Creality Ender 3 with a (golden) PLA filament.</p>
<p>This is how the print error looks like. The first layer should be completely filled.</p>

<p>Note: I didn't change anything (neither the filament nor the software) and before it was printing fine with 200 °C.</p>
