This just happened to me, too. Did you say you cleaned the walking foot with alcohol? What about the quilt? I see a bit of this black goo over some of the fabric. How did you clean that?

I cleaned the quilt per the fast instructions of the ladies on the board and cleaned the inside of the walking foot with alcohol. It seems fine now.
I've never had it coming from the needle bar area, but maybe the alcohol swabs would work there, too.
