Inevitably, there may come a time where something goes wrong with this process
and the extruder is no longer able to push plastic through the nozzle. These jams
or clogs are usually due to something inside the nozzle that is blocking the plastic
from freely extruding. While this may be daunting the first time it happens, but we
will walk through several easy troubleshooting steps that can be used to fix a
jammed nozzle.
11.1 Manually push the filament to extruder
One of the first things you may need to try is manually pushing the filament
into the extruder. Open Anet3D’s Control Panel and heat your extruder to the
appropriate temperature for your plastic. Next, use the Control knob to extruder
a small amount of plastic, for example, 10mm. Please refer to “Tutorial of filament
drawing out and push in”. As the extruder motor is spinning, lightly use your
hands to help push the filament into the extruder. In many cases, this added force
will be enough to advance the filament past the problem area.
11.2 Reload the filament
If the filament still doesn’t move, the next thing you should do is unload the
filament. Verify that the extruder is heated to the appropriate temperature, then
push the filament into extruder and draw it out quickly. As before, you may need
to apply some additional force if the filament isn’t moving. Once the filament is
removed, use a pair of scissors to cut away the melted or damaged portion of the
