Hi all. I rec'd. a new Singer ProFinish serger and up until a week ago was sewing fine. Last week something happened where I broke like 5 needles. Today it sewed somewhat but now both needles are scraping underneath and co me unthreaded or the thread snaps after a stitch or two. It seems it's scr aping on the stationery knife underneath. Any advice for how to remedy thi s problem? I'm using inexpensive sz. 16 needles. Could it be the needles I'm using?
