4. Feed the filament through the filament guide (the hole at
the top of the Polar3D pr i nter). ( Having the filam ent pr o p -
erly guided keeps the filament from flopping wildly from the
spool to the print head.)
5. St i ck the end of the filament into the feed hol e at th e top of
the print head.The“feel”ofthistakesabitofgettingused
to: when sticking the filament into the feed, you must push
past some initial resistance: you must push the filament in
far enough to engage with the fila m ent drive gear inside the
print head.
6. If you want to check whether the filament is all the way in,
raise the temperature of the printer to 180°C,

and slowly
hand feed the filament through. Seeing a string of molten
plastic get extruded tells you you’re ready to print!
8.4.2.2 Unloading filament
If the filament is still warm, you should be able to simply pull
the filament straight up and out of the print head.
If the filament is stuck , raise the extruder temperature to
200°C.

Once the filament has softened, you should now be able
to pull the filament straight up out of the print head.

To set the temperature of the printer, you may use the Polar Cloud printer dash-
board’s temperature dial. Alternatively, you may use the “Controls”screenof the printer
local web interface. If you are using a direct cable connection to the printer and Repetier-
Host to control the printer, under Repetier-Host’s “Your Printer”, use the controls on
the “Manual Control” screen to set the extruder temperature.
