Steps to Changing Filament
1. Preheat the hotend to the correct temperature. If you are switching
between different materials (i.e. PETG to PLA), it is suggested to load the
filament at a temperature between the two ranges. This will soften the
PETG enough for getting it out of the hotend and the PLA will not be
burned when you load it.
2. Push the lever on the extruder to the left and engage it into place with
the lock knob.
3. Remove the existing filament by spinning the spool backwards. You can
also remove the white PTFE tube, at the connector on the hotend, if it is
easier to pull the filament directly out of the extruder.
4. Once the old filament has been pulled out of the tube, put the new
spool of filament on and follow the filament loading steps from the prior
section.
5. When printing, immediately after changing the filament, remember to
preheat the hotend and heated bed to the appropriate temperature
for the new filament.
