I have an SWF 1504 and I was sewing hats last week. After they finished I did some oiling and maintenance, and when I went to sew a jacket later that same day the frame won't move. It doesn't move with the frame moving keys, or when it is sewing the design. I have turned it off and unplugged everything, let it sit over the weekend and it still doesn't work. Nothing is disconnected, there are no error codes, and when the machine is off I can manually move the frame. Anyone have any suggestions? The service guy can't come for a month and I have stuff to sew! Thank you!
