 The SD card must be no larger than 2 Gb.
9.2 Reloading the extruders
See “Load the extruders” (page 31) for all references:
 Remove pressure bearing.
 Heat up the nozzle to extrusion temperature (see Extruder control, page 37).
 Pull remaining filament out of extruder using pliers.
 After removing the remaining filament, follow the instructions in the “Load the
extruders” section (page 31) to load a new filament.
 Purge the extruder (page 38) until the old material is completely flushed out. See
caution note below about purge temperature:
If a new material is being loaded in to the extruder, purge at the
temperature of the material which has the highest melting point. E.g. if
PLA is being loaded into an extruder which previously had ABS, purge
at 260 °C. This ensures that the old, higher melting point, material will
melt and fully flush out. Failure to do this will result in a blocked nozzle,
as the higher melting point material will remain frozen in the nozzle.
