Recommended maximum extrusion temperatures for materials:
Material
Extrusion temperature (°C)
ABS
260
PLA
195
Note: Extruders share power, therefore an extruder will heat up quicker if it is the only
extruder with a high target temperature.
6.9.3 Purge the extruder
 Ensure filaments are loaded into the extruders, as defined in the section “Load the
filament”, page 31.
 Make sure the springs on the extruder pressure bearings are fully compressed.
Compression needs to be adjusted from this setting.
 Proceed by purging one extruder at a time:
 Heat the extruder to the maximum temperature defined below, depending on the
material in the extruder:
Material
Extrusion temperature (°C)
ABS
260
PLA
195
 Once target temperature has been achieved, turn the RPM up to 15.
 If the motor on the extruder stalls (you will hear a ‘clicking’ sound) release the
pressure on the filament by unscrewing the pressure bearing bolt with the hex driver
until extruder motor stops stalling (motor will run without clicking). After this point,
unscrew the bolt another half turn to ensure the motor does not stall during
operation.
