 Observe the end of the nozzle. A thin bead of molten plastic should come out of the
nozzle. Depending on how far the filament was loaded into the extruder, this could

 Allow material to purge for a few seconds before reducing the RPM to 0.
 Repeat for each extruder.
 Turn the machine off to allow the nozzles to cool.
 As the extruders cool, clean the nozzles (see “Check the hot-end nozzles are clean”,
page 20).
 Dispose of all waste filament from the nozzle.
