My Ultimaker 3 Extended Will not extrude material

[AngusB112 0]

I have tried:

• unloading and loading the material,
• changing the printcore temp,
• replacing the printcore itself

I am using black Nylon Filament from ultimaker, with an AA 0.4 Printcore.

Any help is much appreciated.

1. Clean the printcore with pla or cleaning filament. 

2. Make sure the nylon is dry. If your printer is fully enclosed you can heat the bed to 60° and leave the roll in there for a coupple of hours. Moisty nylon is prone to clogging nozzles.

 

You can also open the feeder to clean it. Last time I had problem with random under extrusions I opened it and found a small piece of filament that probably interfered at its own will.

 

Be careful though, there's a spring inside that wants nothing else but jump out ejecting other parts...

took the feeder apart, spring monster jumped out and gave me a fright, but no obtruding filament buts to report.
