<p>I use OctoPrint on an Ubuntu system with a M3D printer.</p>

<p>Midway through a recent print, the filament just stopped extruding although the motor-functions of the printer were proceeding fine. Since then, every print I attempt has trouble extruding proper amounts of filament. It's always not enough. The output is stringy and not cohesive.</p>

<p>I'm thinking there may simply be a clog in the extruder and wondering the safest way to remove it.</p>

<p>The weird thing, though, is that when I use manual control and extrude at, say, 220C, the filament comes out fine.</p>

<p>You can see the raft definitely isn't printing right. Way too little output:</p>

It can also be freshened up with a gentle spray of water, smeared flat, and redried, or more gluestick added on top. It will really come down to your preferred workflow. </p>\n"}]
