Loss of Extrusion

Diagnosing Loss of Extrusion

Occasionally, the machine's head may experience loss of
extrusion. This will be evident by observing one of the following:
• Seeing the head moving with no material coming out of
either liquefier tip
• The height of the model and support materials are not
equal
• Sagging structures due to lack of support materials

To diagnose loss of extrusion:

1. Press Cancel and remove any parts from the machine.
2. Insert a new plastic modeling base (substrate).
3. From Idle, enter Head Maintenance
a. Using the keypad, press Maintenance.
b. Press Next. The head will come to rest in the center of
the chamber and the Z-axis table will move. The
display now displays Head Maintenance.
4. Determine if there is an extrusion problem by pressing
Forward. Watch both tips for several seconds, looking for
extrusion.
5. Press Stop to stop the extrusion.
If material steadily flowed from both tips, the head is not
experiencing loss of extrusion. Push Done to return the
machine to an idle state. If material did not extrude from
both tips follow the procedure in the following section,
