I would take it in to get an estimate of what is wrong and how much it will cost. Always wise to have a good older reliable DSM as a backup. Sometimes when you dream of all the functions you can have, you end up only using a couple of the fancy stitches. I forget to set my needle down most of the time and find that using a piece of scrap fabric to end and start my stitches works better than any thread cutter. Just getting OLD and set in my ways.
