Maintenance & Troubleshooting Manual
Figure 3.2.5 Damaged Ceramic Heater from Applied Force
NOTE
–
In the photo of the Damaged Ceramic Heater, the ceramic is brittle, and once cracked, will
loosen and further break down on each nozzle heat-up/ cool down cycle leading to rapid failure. To avoid
this, the assembly is held together by opposing force that happens as the heat bridge is screwed into the
nozzle, both into the ceramic heater assembly using the torque screwdriver.
3.2.7
Tool for Nozzle and Heat Bridge Service
Your printer comes supplied with a small, stainless steel wrench suitable for gripping the square surface
provided. A 7mm deep socket is (included in the optional Tools & Spare Parts Kit) used to grip and
secure the nozzle against the heat bridge at the correct torque value. 1.3Nm
Use opposing force only to secure assembly for use in the printer.
IMPORTANT
- These are the only surfaces you should use force on when servicing an extruder.
