Dremel 3D20 Original Instructions Manual page 20

11. Your Dremel 3D20 will begin to heat the extruder.
The Dremel 3D20 touch screen display will update
you when extruder is "HOT" and ready to load.
12. Once your Dremel 3D20 is ready to begin
extruding, gently guide the filament into the
extruder until it feeds through on its own.
WARNING
DO NOT TOUCH THE EXTRUDER
!
TIP DURING DREMEL 3D20
OPERATION OR UNTIL IT HAS COOLED DOWN TO AT
LEAST 60°C (140°F). CONTACT WI TH THE
EXTRUDER TIP DURING OR AFTER OPERATION
BEFORE TIP HAS COOLED MAY RESULT IN
PERSONAL INJURY.
13. Filament will then be drawn into the extruder and
begin to exit from the heated tip at the bottom of
the extruder. After the filament has extruded from
the heated tip, press the return arrow to complete
the loading process. Carefully remove excess
filament without touching the hot extruder tip.
NOTE: Your Dremel 3D20 was tested by building
objects before leaving the factory. These test
objects may have been made with a different
filament color than you are using. Therefore, a
small amount of filament may be remaining in the
extruder. When loading filament for the first time
make sure to allow filament to exit the extruder
until your filament color is consistently visible.
CAUTION: Use extra care to not damage the
extruder tip when clearing debris. Dremel 3D20 will
not work properly with damaged extruder tip and
will require replacement.
14. After filament has been loaded, ensure the extruder
tip is clear of any debris. Carefully remove debris
with needle nose pliers to ensure the extruder tip
is clean.
15. If filament does not get pulled into the extruder or
does not come out of the extruder tip, tap "Cancel".
Tap "Setup" then tap "Unload Filament". Once your
Dremel 3D20 alerts you it is ready, gently remove
the filament from the top of the extruder and repeat
the filament installation steps above. Reference
troubleshooting section for further advice.
BUILD PLATFORM PREPARATION
WARNING
DO NOT TOUCH THE EXTRUDER
!
TIP DURING DREMEL 3D20
OPERATION OR UNTIL IT HAS COOLED DOWN TO
60°C (140°F). CONTACT WITH THE EXTRUDER TIP
DURING OR AFTER OPERATION BEFORE TIP HAS
COOLED MAY RESULT IN PERSONAL INJURY.
CAUTION: Before every build make sure that the build
platform is covered with Dremel specified build tape.
Use of improper build tape may result in equipment
damage and poor object build quality.
LEVELING BUILD PLATFORM
It is important you level the build platform every time
you replace the build tape or reinstall the build platform
to ensure that the build platform is evenly spaced
from the extruder head. Make sure to remove any air
bubbles from between the build platform and the build
tape. Not leveling the build platform or eliminating air
bubbles may cause objects to not build properly.
Wait for the extruder head to cool to at least 60C
(140F) before leveling build platform. Extruder
temperature can be monitored on the touch screen.
(See page 11.)
1. Make sure you have placed build tape over the
build platform. Applying build tape to the build
platform after leveling may effect the consistency
of your object.
2. Tap "Tools" on your Dremel 3D20's touch screen
and tap "Level". (See page 14.)
3. The extruder and build platform will move into
position to level the build platform. You will first
level the front left section of the build platform. The
three knobs under build platform are used to raise
or lower the build platform on the left, right, and
rear of the build platform.
4. Place the level ing tool between the extruder and
build platform. If the leveling tool cannot slide
between the extruder and build platform, adjust
the appropriate knob (turning counterclockwise)
until you can slide the leveling tool between the
extruder and build platform with some resistance.
If the leveling tool can slide between the extruder
and build platform too easily, adjust the appropriate
knob (turning clockwise) until you can slide the
leveling tool between the extruder and build
platform with some resistance.
