I have the same machine and it is a challenge to get it working. Look in you Manuel as to which setting to use. I think without looking that you use the sensormatic with the foot that comes with the machine. I bought another foot that uses the other setting. It is very picky about what thread you use so try various threads. Don't go too fast as it doesn't like that either. You don't have to make any other changes to the machine as.those automatically are set when choosing the free motion setting. I suggest you go to the dealer for a demo and some work time under their guidance. I also find a metallic needle works best. Please fell free to PM me as I feel your pain!
