When the nozzle is worn out or clogged beyond repair, you can replace the nozzle with a new one.
Replacement procedure:
① Before replacing the nozzle, please reduce the nozzle temperature to room temperature to prevent burning when replacing the nozzle.
② Move the Z-axis up about 150mm or so to make sure there is room for a change.
③ Remove the silicone sleeve from the hot end.
④Use a 2.5mm Allen wrench to remove 2 screws and loosen 1 screw on the heat sink, remove the old nozzle.
⑤Take the new nozzle, put the smooth end against the hot end, use a 2.5mm allen wrench to reinstall the 2 screws back in, and tighten the screws on the heat sink.
⑥ Put back the silicone sleeve.
Replacement steps:
Take out the feed tube retainer.
Use a 1.5mm Allen key to insert into the upper hole.
③Hold the plug of the pneumatic connection with one hand and pull out the PTFE tube with the other hand.
④Insert a new PTFE tube until it is flush with the Teflon catheter seat port.
⑤To install the return tube retainer, pull out the 1.5mm Allen wrench.
