TCT, I have that same machine and would like to have some advice for you, but I don't know what "SFM" means or a couple other of the abbreviations in the question. Sorry, it is probably something that will make me say, "of course". There are a few different settings to use for free motion and the machine is a little fussy about which setting with which foot. Keep trying because it will do nice free motion for you. Later on I will check my manual for things that I have marked and found helpful.
