Yes my Janome acts up occationally. With FMQ try rethreading it or make sure you set things up right according to the instructions. The right needle and thread will also help. Then my machine works well. Today I didn't have everything right and boy did I have problems for a while. It seems to be all in the set up. For got to say that I have a 6600 Janome. Yes at times it gets sinsitive, but I love it. It took me a while to get use to it. I was use to a Sears that was 20 some years old. Eveything has it little quirks, even me. :-D
