If filament does not feed through hot end, the hot end is not seated flush in its mount. Push the
hot end as far as possible into its mount.
12.
If filament still does not feed, remove the extruder top that holds the extruder motor into place.
Lift up the extruder motor and extrude out about 1” of filament. Insert filament into the top
hole of the hot end and set the extruder motor back on the extruder bottom. Replace the
extruder top to lock down the extruder motor. Extrude filament until it comes through the hot
end nozzle. The filament will not feed if hot end temperature is less than 200 C.
13.
When using a new roll of filament, watch how the filament is leaving the spool when
beginning to print as well as when spool is placed on the printer. If the filament is wound too
tightly, it can jump off the spool and become trapped between the spool and the printer.
