3) Inspect the material carefully. Make sure it is free of kinks and nicks. If you
are using ABS, make sure to take a spool from a sealed bag.
4) Inspect the spool. Make sure it is wrapped tightly without any tangled or
overwrapped material. Undo any tangles or overwraps.
5) Cut off any kinks or nicks with a sharp knife.
6) Using both hands, press the spool with the filament wound clockwise onto
the mount until it locks into place. Make sure the spool does not rest on its
tension ball.
7) If you are loading ABS, open the head and insert the filament seals using
the tool supplied by Stratasys.
8) Press the "LOAD" button.
9) Feed the filament gently into the guide hole on the bottom of the sensor
block (do not force it), while continuing to unspool filament, until you feel
it being pulled into the FDM head. Allow it to feed until filament comes
out past the open part of the head.
Do not tighten the seals beyond contact resistance.
11) Cut the filament to a square edge with a sharp knife, and push it back until
only 1/8 inch is sticking out from the rear portion of the head.
12) Feed the filament into the head from the rear until the motor pulleys grab it.
13) Make sure filament is coming out of the FDM tip.
14) Inspect the flow. It may sputter if there is a blockage or other problems.
If filament does not begin coming out of the tips within 20 seconds, turn off
the load, open the head, and check for anything that might prevent filament
from flowing through the tip.
15) Press the "LOAD" button to stop loading material.
16) Clean the tips with a steel brush.
17) Back up the spool until the filament is taut.
18) Close the dry box door and secure it with the latches.
19) Close the back door.
