Trouble shooting
Sometimes a bulge or kink in the filament causes a jam.
In this case, make sure the cause of the jam is removed before resuming the print job.
Printer has run out of filament.
Put a new spool of filament on the printer. Cut off the filament so that the end is flat. Feed the filament through the
dust filter and the Teflon tube. Insert the filament into the print head.
If the extruder is at its target temperature, feed through the new filament.
The printer will then push the old filament through the extruder.
When you are sure the new filament has properly entered the extruder, resume printing.
Very soft material (like Flex material).
The filament can get squeezed so much by the clamping mechanism that the detector misjudges the amount of
filament coming through.
It may help to dec
rease the clamping range (see “Howto adjust filament clamping range”).
A clogged hot
end that is preventing the filament being fed through.
Nozzle is too close
to the bed or printed object.
This can happen if the bed is not leveled right or the object is warping up.
The filament cannot flow through the nozzle properly, causing the filament feeding mechanism to slip or stagnate.
Level the bed and make sure the first layer adheres really good to the heated bed.
A clamping range that is too small. See
this article
.
No filament is coming out of extruder
The most common causes to get a clogged hot-end are (ordered from most common to least common):
Chosen print temperature too hot.
Try printing at the recommended temperatures for the chosen filament. For instance, printing PLA at 210 degrees
might work in some cases, but it is critical. The top part of the hot-end will become near the critical 60°C where the
filament becomes too soft, too soon and causing a clog.
Fan cap not closed.
The front fan cap should be flipped closed all the time when the extruder heaters are active. Failure to do so can
cause the cooled part of the extruder to become hot, and the filament will soften or melt too early, causing jamming.
Hot end not really clogged
Sometimes the extrusion is partly blocked because the nozzle is too close to the bed or to the printed object. Please
check if the z-homing of the printer is correct. Check if the printed object is deforming in such a way that it moves too
close to the nozzle.
Bad quality filament.
Make sure to get good quality filament. Dimensional tolerances and also bad consistency of the material itself can
cause trouble during printing.
Dust collector not applied around the filament.
