into the top center of the printhead with the burnt end up (use a pencil
eraser etc. to push it all the way in) C.25 If the filament goes all the
way thru the feed tube & moves freely when the purple feed gear on the
extruder (hanging from the top of the Rostock) is turned skip C.26-C.33;
if the coupling at the end of the feed tube is not clogged skip C.26
C.26 Using a 5/64" bit in a hand drill, carefully drill out the clog
(Caution: the coupling may still be hot) C.27 Unscrew the coupling at
the other end of the feed tube where it connects to the extruder C.28
Try to pull the filament out of the tube; if it won't come out STOP and
get expert help; the tube may need to be replaced C.29 Check if the tube
is clear (i.e., by pushing the feed tube snake thru it); if it isn't &
the clog can't be pushed out STOP and get expert help; the tube may need
to be replaced C.30 If the end of the filament is swollen, damaged, or
blunt trim off any swollen or damaged part and try to make the end
slightly pointed C.31 Insert the end of the filament into the feed tube
C.32 Screw the connector back into the extruder C.33 Feed filament by
turning the purple gear on the extruder clockwise (as viewed from the
front) until it emerges from the other end of the feed tube (requires a
lot of turning; if there is a problem the instructions for changing the
filament may be helpful) C.34 If the end of the filament is swollen,
damaged, or blunt trim off any swollen or damaged part and try to make
the end slightly pointed C.35 Retract excess filament by turning the
purple extruder gear counterclockwise until only a tiny amount sticks
out C.36 Screw the coupling (Caution - it may still be hot) back into
the top of the printhead C.37 Repeat steps C.2-C.6 if needed to select
NOZ temp: C.38 Set temperature to 225 by turning knob C.39 Repeat steps
C.8-C.12 C.40 Wait until NOZ temp: reaches around 225 C.41 Slowly turn
purple gear clockwise (or use the extrude command) until filament starts
to emerge (if the gear becomes hard to turn but no filament comes out it
may have reclogged; start over (it has taken a couple tries before final
success)) C.42 Repeat steps C.2-C.6 C.43 Set NOZ temp: to 215 by turning
knob C.44 Press knob C.45 Put feed tube snake away if you used it C.46
If you are going to print now stop here C.47 Set NOZ temp: to 0 by
turning knob C.48 press knob ins3DRostockmaint - June 13, 2019 version
