I'm having basic trouble with my bernina 730. The bobbin stitch isn't completely straight...sorta wavy. I have cleaned the machine, changed the needle, changed the thread, changed the tension, changed the feed dogs....can't get it to make a perfectly straight stitch. Any ideas or help? Thanks.

When have you last had it serviced?

Just had it serviced...that is part of the problem. It was doing great before I had it serviced. It is almost like the bobbin box is messed up? Just can't figure it out. I've tried everything.

I think they may have done something wrong in the servicing. I'd take it back in. Most places have a guarantee on service.

Don't know if you got my last message. I just had it serviced. It hasn't sewn right since I got it back. It was clean, etc..., but my stitches just aren't right.

Ok...thanks for the response.

If you took it in and it was sewing fine and then it came back wonky, they definitely need to make it right.

If you have it on the straight stitch setting, you haven't by any chance, knocked the zig zag stitch width setting a tad to the right?

No..checked that but thanks....
