I use OctoPrint on an Ubuntu system with a M3D printer.
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.
I'm thinking there may simply be a clog in the extruder and wondering the safest way to remove it.
The weird thing, though, is that when I use manual control and extrude at, say, 220C, the filament comes out fine.
You can see the raft definitely isn't printing right. Way too little output:
