Stitch Problem

I purchased a used grand quilt 18.8, it was a demonstrator, used very little but have set it up and having problems with the stitch not catching. We checked the encoders, changed the o rings which were bad, changed the needle, rethreaded it, checked the bobbin, oiled everthing from owners manual. Not sure what else I can do. I did change thread as it was always fraying and breaking.
