If the purge was successful:
i.
Continue to run both filament motors forward and slowly swivel the head closed. Be
careful to not pinch the filament or the head wiring when closing the head.
ii.
Once the head is closed, tighten both of the swivel head screws, ¼ turn.
iii.
Verify material continues to extrude through both tips for an additional 30 seconds,
then press
Stop
to halt extrusion.
iv.
Push

d.
If material did not purge, continue with the following steps.
6.
Snip both filaments approximately 1 inch from the fixed part of the head (see
Figure 32.
)

Materials coming out of feed tubes
7.
Remove the filament from both drive block assemblies, see
Figure 33.
if there is enough to
remove by hand.
a.
From the display panel, press
Reverse
...
This causes the drive wheels to reverse, so the material filaments can be backed out of
the liquefier.
b.
Grasp the filament from the drive blocks with your fingertips, and gently pull it out of the
drive wheels, see
Figure 33.
Repeat for second filament. If you are unable to easily
remove either filament, leave the filament in the drive block for now.
Note:
On rare occasions, the material may NOT be extending out from the
feed tubes. If this occurs, push in the appropriate cartridge to unlatch it. Pull out
the cartridge to expose the filament and manually feed the filament through the
feed tubes until the filament comes through the back of the head. Pull the
filament from the head while inserting the cartridge. Once the cartridge
latches, pull an additional 6 inches of filament through the head (to make sure
the filament is not caught at the cartridge receiver). Then snip the filament
approximately 1 inch from the fixed part of the head.
