Sherryl, the thread guide is fixed, so no adjustment.
The grands are spending the day and night tonight, so no sewing. But tomorrow I will clean the bobbin trace again and see if that helps. Them Monday I will contact Nolting and if they cannot get it fixed call Hinterburg and have them pick it up for replacement again. I don't object to having to adjust new machines, but this has reached the point of absurd.
