6. Snip the filament line from the cartridge close to the drive
wheel.
7. Make sure that all loose filament is removed from the affected
liquefier inlet area.
8. Check for loose material in the other liquefier inlet area. Clean
the area as necessary.
Inspect the Teflon Shield
If the printer experiences a loss of extrusion (LOE), material can
build up around the Toggle Plate Assembly. The Teflon shield is
designed to prevent this material from reaching the heater blocks,
reducing the amount of maintenance required to return the printer
to service. To make sure that the Teflon Shield is able to perform
efficiently, it is recommended that it be inspected when returning a
printer to service following a LOE event.
1. Remove the liquefier tips - refer to “Removing Tips” on
page 49.
2. Inspect the Teflon shield - refer to “Inspecting the Teflon Shield”
on page 50.
3. Install the liquefier tips - refer to “Liquefier Tip Replacement” on
page 49 .
4. Perform a Tip Calibration (every time a tip is installed, a Tip
Calibration must be performed).
A. If you are installing new tips, perform the Tip Calibration
per “Tip Calibration” on page 55. After the calibration, the
tip odometer will be re-set to zero.
B. If you are re-using tips, perform the Tip Calibration as
follows (the tip odometer will not be re-set to zero):
(1). Perform a Z Calibration; from
Maintenance >
Machine
, choose
Tip
>
Calibrate Z
.
The printer will automatically build a Z Calibration part,
measure the part and calibrate the Z Axis for tip depth
and tip level (approximately 5 minutes).
(2). Perform an XY Calibration; from
Maintenance >
Machine
, choose
Tip
>
Calibrate XY
.
