Machine skipping stitches only while fmq/help
My Pfaff 7570 has started skipping stitches while fmq. I have cleaned it, oiled it, changed needles and thread and fiddled with the tension. I've done everything Mr. Google has suggested.I don't know what else to do. The machine has been a workhorse but it is 16 years old. Do any of you have any advice. I can't really afford to buy another machine right now. As always, thank you for your help.
