Which company store did it come from? I ordered mine off Amazon years ago and no issues. I did call the store (Mr. Vac & Mrs. Sew) He helped me with questions about the machine before I ordered it.
The PE 770 is really fussy about the bobbin and how it's threaded. If there is even the tiniest speck of lint it sews wrong. Take a magnifying glass and take apart the bobbin area like you do on your home sewing machine. Carefully inspect where the metal meet the plastic parts. I found a small speck of lint there that was messing up my stitches.
Saved me a $175.00 service call at the LQS who services Brother machines.
When threading the bobbin through it's area make sure you hold a bit of tension not much just enough so it sets and runs around where its suppose to go. My Brother SQ9000 does the same thing it is really fussy about how its threaded.
i hope this helps....pm me if you need any more help.
I didn't add the link "home sewing machine" ......lol QB is at it again.
