Help! - Juki HZL F-300
I have a new Juki HZL F-300. I am sewing a straight stitch using the automatic thread cutter. I have checked the threading on both the thread and the bobbin numerous times. I have changed the needle several times.
Issue: the threads nest at the end of my seam. Both threads cut but the thread somehow threads itself through the fabric twice and I end up with a tail. So every time I start a seam there is a long thread from the thread itself.
I hope I explained this well. Does anyone have suggestions on how to solve the problem?
