I have a Brother PC 8500 that I can not get to FMQ. It is a wonderful machine and I bought it used for a great price. Everthing else works like a dream, even the embroidery, but everytime I try FM it breaks a needle. I have done FMQ with other machines, I have changed the needle, lowered the feed dogs, tried different threads and bobbins, cleaned it and even manually moved the needle and it looks like it is fine. BUT when I start sewing within two or three stitches the needle breaks EVERY time. Is there anything else I could try or just take it to a repair shop?
