I think I remember someone saying that moving a thread to Problems & Support doesn’t notify staff the same way opening a new thread there does. But I could be misremebering.
On mine about a third of the ribbon cable is glued directly to the gantry surface. This is so the ribbon will track correctly as it folds during the left/right movement of the head. My ribbon has a good bit of distance between it and that screw. Two possibilities: either the ribbon is glued slightly askew or the glue has let go.
