Hello, I’m having the exact same issue of the back and forth motion never advancing to the next stitch. I bought the machine used so there’s that of “who knows what’s been done to it”. However, the first issue was needing a new belt (check), taken care of now everything’s moving. Now my issue is what this discussion is about. The only thing I’ve done is take the set screws to look at them and not switch them; ensuring that the set screw was pointed and the other screw was flat which they were in their correct spots. Also, I haven’t adjusted anything yet because I don’t know what l ready correct and what’s not. I don’t want to adjust something and not know how to reverse it.
