Ugh! Know what you're going thru. I have a BL and it did the same thing..drove me crazy..I paid for this "added" feature and it gave me grief...I was ready to throw it out the basement window(still do some days).... Packed it up and took it to the dealer/tech...told him fix or put it in the middle of the road and let a semi smash it.....well yes, he fixed it...I guess there is a way they can. It now leaves enough thread to begin again....I still am not "thrilled" with the hairy knot it makes but better than having to manually (auto) re thread! And I paid for all this technology!
