ok so i'm a dork and this machine needs a cover in order to free motion to cover up the feed dogs. I thought turning the wheel to 0 would lower the feed dogs and the repair man said "are you lowering the feed dogs?" i said "i'm turning the wheel to 0 and nothing is happening" he laughed and said I was chaning the presser foot pressure. duh! I just ordered a foot plate cover and then I should be all set :)
