have you changed the filament spool ?

I have arule that if one roll of filametn clogs more than once i throw it away.
Or you could send it back I suppose.

I had some amazing silver/grey pla last year. Just the best stuff to print with ever, 3 rolls perfect. One killed clogged.
I pulled a bunch of filament off the spool. Then tried it again, clogged.
Pulled 50 metres or so off and tried again. Clog.
Threw it away.

I think som,etimes the colourant just doesn't get properly mixed or maybe some of the other additives are not right.
As manufacturers refuse to state what's in filament - it's all guesswork.

But a spool that clogs more than once will most likely continue to clog through the whole spool.
