What the heck? Can a tension problem "build up" and do like a release thing every few feet? I can't understand this.

Some background. I've just begun using large spools of thread and have rigged up a contraption (thanks to hints from QB members) where the large spool sits to the right of my machine. I am guessing somehow that had changed things but I'm not sure what to try and fix first.

Thanks for all help.
