POSITIONING THE EXTRUDER NOZZLE

Proceed as directed below when removing and re-fitting the extruder nozzle.
- Place the magnetic support block (B) of the comparator (A) on the side of the insertion drum (C).
- Bring the comparator (A) to one end (1) of the nozzle (F).
- By using the handwheel, turn the drum (C) until the comparator (A) reaches the opposite end (2) of the nozzle (F).
- There should be a difference in level along the plane where the measurements are taken, i.e. "E" must be between
0.0 and 0.03 mm.
The lowest part should be at the point where the cutter moves down close to the nozzle.
If the measurement is incorrect:
- Loosen the screws (D), which secure the nozzle to the extrusion head, and turn the nozzle until the correct
measurement is obtained.
- Fully tighten the screws (D).
