Troubleshooting
Problem Cause Corrective Action
Extruder head building off
center
Dremel 3D20 has lost track of
the extruder head’s exact
location and is failing to build.
Sending the extruder head to the
home position will recalibrate the
Dremel 3D20. Cancel your object,
clear build platform, send the
extruder head to the home position,
and restart the object.
PLA is not extruding or sticking
to the build tape properly
This can be caused by the build
platform not being leveled with
the extruder head.
Leveling the build platform will align
the extruder head and ensure a better
object quality. Cancel your object,
clear build platform, level the build
platform, and restart the object.
Dremel 3D software froze
during use or computer froze.
Sometimes software isn’t as
smart as you are and locks up.
Save any open files if possible and
either restart the Dremel 3D software
or your computer.
Dremel 3D20 froze before my
object started.
Dremel 3D20 may have
received conflicting commands.
Turn power switch off, wait 30
seconds, and turn power switch on.
3D file loads with a warning
stating that the file is not
closed.
3D file has not been properly
designed and has open
surfaces.
Open 3D file in a CAD editing
software to close all the open
surfaces.
Support material does not
break away during cleaning and
results in decreased quality of
the final object.
Orientation of the part is not
optimized.
Reorient the position of the 3D file in
Dremel 3D to minimize the support
material or place the support material
on a non-critical surface.
Spaghetti mess at end of build. A layer of your object did not
stick properly, model was saved
with minimal surface area
contacting the build platform,
or object was built floating
above the build platform with
no support selected.
Use the preview future in Dremel 3D
to see the first layer height and
position. Build with supports when
necessary.
Part only built halfway. Filament ran out.
Filament clogged during build.
Replace filament and start build over.
See “No filament coming out”.
No filament coming out Clogged extruder Use unclog tool to push through
filament.
Contact customer service
Extruder will not home Limit switch wire failure Contact customer service.
Stringy or fraying plastic layers
on steep overhangs
Object overhangs are too far
apart or too steep (<45degree
angle).
Build with supports.
