Hi,
I have no idea what's up with your machine, I have 3 Babylocks and have had no trouble with them at all, ever. I adore them!
Have you cleaned it, new needle, etc.? I have been taught to oil mine occasionally....not very often.....but think that could be an issue?
Can the dealer help you over the phone at all? Mine would help me. Could be something simple.
Sorry you are having issues......I'd buy nothing but my Babylocks.
Bev
