Nylon printing - Clogged cores

[puydtd47 0]

Hello,

 

I had a problem during printing with Nylon (PA), but noticed too late that UM3 was printing in the air.
Result 2 core blocked including the cover (see photos)

 

Any suggestion how to remove the nylon and clean-up the print head?

No detailed instructions, but it happens from time to time.

You can only try to heat the core and use a heat gun (carefully) to soften the material. 

 

Your print head doesn't look to bad, so I think you should be able to remove the material. 

 

Always check the silicon pad at the bottom of the print head and replace it if you see some burnt spots. This pad is important that the filament cannot get inside the head.
