melted filament coming out top of heat block.

Hello again


I am having another issue with melted filament coming out of the top of the heatblock. How do I fix this problem?

I checked, and tightened the heatblock as much as it would go to the heat sink.

Thanks in advance for the help

Have a look at the howto change the nozzle in my signature.
Do you did the tightening when the nozzle was hot?
