You did not say what you were sewing on. very recently one of my customers got the draw strings of a hoodie sweatshirt jacket caught up in the rotary hook which would then cause a Z axis error. Anything that binds the rotation of the Z axis and prevents the rotary hook from rotating will cause a Z-axis error. This would include lack of lubrication on the rotary hook and have it freeze up... If you can't rotate the Z-axis shaft 360 degrees by hand....find out what is preventing it from turning and you will have found your problem....not how to fix it, but you will have found it.
