Also I was looking at the different materials for nozzles comparing brass to stainless.
Has anyone any experience?
The reason I ask is my E3D jammed again last night and I am a builder at heart so I ordered some stainless and brass blank material

Planning on making some nozzles and coating them on the inside with some slippery stuff after polishing.
I have searched here and read online most material I can find. Nothing much on coatings only polishing.
Just trying to not reinvent something that has been tried already.
Appreciate any tips from users.
