Clean the nozzle (o) if necessary, using a soft lint-free piece of cloth.
CAUTION
The nozzle is hot! Risk of burns!
4. Remove the old filament spool from the filament spool holder (M). If the
spool still contains filament, wrap it up and secure the loose end to avoid
entanglements.
5. Place the new filament spool in the filament spool holder (M). Make sure to
place the spool in the holder as shown in Fig. 7-2 and to check that the fila-
ment string can easily unspool.
6. You can adjust the roller (K) and the brackets (L) in
the filament holder according to the spool diame-
ter and width to ensure secure unspooling (see Fig.
3-4).
7. Feed the loose end of the filament through the fil-
ament guide (D) into the printer and towards the
extruder.
8. Push the lever (b) to the right and feed the filament
through the filament guide into the extruder. Slowly
continue pushing the string into the extruder until
you see extrudate coming through the nozzle. Extrude additional 50-100
mm of filament to ensure that the old filament is completely extruded.
Select Resume in the GUI to resume printing or start a new print.
Filament Change After Out Of Filament Notification
The Out Of Filament notification appears on the display when the extruder de-
tection registers no more filament and automatically pauses the print.
The extruder will be moved automatically into a position that allows easy filament
replacement. This position can be set on the Advanced Menu if the UI.
Note
The extruder can be moved manually via GUI or Pronterface after pausing.
Important: Do not trigger the end stops as the print will then be aborted!
Note
Due to security reasons the extruder will be automatically cooled down after 15
minutes. To change the filament after extruder has cooled down you have to turn
on the heater again. This time can be set on the Advanced Menu if the BigRep UI.
