PRINTING PROBLEMS/CONNECTIVITY PROBLEMS
PROBLEM
Can't load filament into the Smart
Extruder+.
Can't remove filament from the
Smart Extruder+.
Filament breaks between the
spool and the Smart Extruder+.
Filament won't extrude from the
Smart Extruder+.
Printed object is stuck to the
build plate.
Object peels off the build plate
during printing.
The Smart Extruder+ is installed,
but the MakerBot Replicator
Mini+ does not recognize it.
SOLUTION
Try unloading and loading again. Hold the Smart Extruder+ in
place and try pushing the filament through. As long as you are
holding the Smart Extruder+ in place, pushing on the filament
will not damage it. Be sure to insert the filament and not the
filament guide tube into the Smart Extruder+. Also, make sure
the filament end has a clean edge before inserting it into the
Smart Extruder+. A clean edge will allow for easier insertion.
Try running the filament load script and allowing the plastic to
extrude for a few seconds. Then try unloading again.
Ensure that the filament unwinds counterclockwise from the
spool. Always unload any filament left in the Smart Extruder+
Try unloading and reloading the filament.
If the object is still stuck, take a thin metal craft spatula and
carefully work the blade under the object. When the blade is
most of the way under the object, twist the handle slightly.
The object should come free. Never use a knife or sharp tool
to remove pieces of the object or pieces of the raft. You can
damage the build plate and also injure yourself.
Calibrate the Z offset. If you are still experiencing issues, man-
ually reduce the Z offset. Ensure that the build plate is clean.
Dust and oil from your hands or tears and wrinkles in the grip
surface covering the plate can prevent objects from adhering.
Wipe down the build plate with a clean, lint-free cloth.
Remove the Smart Extruder+ and attach the extruder again.
