PASO 14
Extruder reassembly (Part 2)
Check once again the correct position of the hotend. Look from below the
extruder. The heater block should be oriented as seen in the picture. Perpendicular
to the printed parts, with the cables pointing to the back.
Guide the thermistor cables above the thick heater cables.
Take a look from the side of the extruder. The nozzle should be slightly below the
printed fan-shroud.
If it is significantly lower than in the picture, your hotend isn't inserted correctly.
PASO 15
Extruder reassembly (Part 3)
Carefully and slowly push all the parts together.
In case of any significant resistance STOP immediately and check, which part is
blocking the movement.
Tighten the two M3x40 screws on the front of the extruder.
Now, look at the back of the extruder. Re-insert and tighten up the M3x40 screw on
the right.
