WEEKLY MAINTENANCE

VACUUM THE BUILD ENVELOPE

The purge chute is designed to catch purged material debris and pass debris into the purge bin for disposal.
However, some excess material debris may fall into the bottom of the build envelope. Do not allow excess
material debris to accumulate in the build envelope as this could cause damage to the printer. Vacuum the build
envelope on a weekly basis to remove build material debris and dust.

CLEAN/INSPECT TIP WIPE ASSEMBLY

You should clean the tip wipe assembly once a week. While cleaning the assembly, inspect the flicker/brush
assemblies and purge ledges for wear and replace parts as necessary when wear is detected.
The flicker/brush assembly is replaced as a single unit. Once material is purged from a tip, the flicker portion of
the flicker/brush assembly passes across the tip's opening, cutting purged material off in small segments. The
brush portion of the flicker/brush assembly then passes across the tip's opening cleaning the tip and its tip
shield. As a result, the flicker will wear at the location where the tip contacts its surface and eventually develop a
notch large enough for the tip to completely pass through the flicker; a notched flicker cannot properly cut
purging material. Similarly, material can become embedded within the bristles of the brush resulting in clumping;
clumped bristles cannot properly clean a tip or its tip shield. The flicker should be replaced once a significant
notch develops, and the brush should be replaced whenever bristle clumping (which cannot be removed with a
brush) is apparent.
A purge ledge is replaced as a single unit; you do not need to replace a model side purge ledge and support
side purge ledge together. Segments of purged material that have been knocked away from a tip's opening by
the flicker drop onto the purge ledge. Purged material is then balled up by the purge ledge, and transported
through the purge chute into the purge waste bin. As a result, material buildup will accumulate on the surface of
the purge ledge. A purge ledge should be replaced whenever excessive buildup has accumulated on the ledge's
surface.
To clean the tip wipe assembly and inspect its components:
1. Ensure that the printer is stopped (idle) and is not building.
2. Open the oven door.
Hot Surface: Depending on how long the oven has been allowed to cool,
components may be hot. If the printer's thumbscrews are hot, wear the safety
gloves provided in the Welcome Kit to perform all remaining steps.
3. Remove the two thumbscrews securing the purge chute access plate.
4. Carefully remove the purge chute access plate by pulling it up and out of its slot within the oven
frame.
Note: The glass pane within the purge chute access plate is loose and may
potentially break. Use caution when removing the purge chute access plate to
ensure that the glass pane does not fall from its slot.
