Not very happy all was going well, sewing my first design down loaded and transferred to memory card half way through the sewing and my machine started making a horrible noise. I think it is the bobbin case as it sounds the same as the problem I had with my none embroidery machine which I sorted out.
the bobbin case had been pulled out of alignment.
I have the correct needle and correct bobbin thread and have had the bobbin case in and out making sure there is no thread tangled up I'm sure I have replaced it correctly thinking it might now be the tension it stops sewing with an awful noise and says ( could be bent needle / tangled thread or bobbin thread or sewing thread needs re threading ) but they are both OK. I have replaced the needle but it is still only sewing a few stitches and then the machine jams up again with this horrible noise I'm sewing on a thin cotton sheet and using stabilizer and sewing with embroidery thread been trying to sort it out for 4hrs have now given up till tomorrow I was so looking forward to seeing it finished, I haven't used my machine for a couple of years it was working lovely last time I sewed with it.
P.S. I hope you can get it going.
Good luck!
Also, try a new bobbin. I have a few that just give me no end of grief, so they get tossed. I hope it turns out to be something very little!! Good luck!
