The Problem turned out to be my Bed Frame. After weeks of back and forth with QIDI and others. QIDI Engineers suggested I loosen the Four Z Axis bearing and reset them according to procedure. But The bearings seemed good so I loosened the Drive Screw Nuts and the bed movement drastically improved. However, I think it is more correct to say that the bed frame was/is bent. Just before this all started I recall my model getting knocked off the bed and under the bed so when the bed came down it bent the be frame.After that I had to reinstall the Parameters file and everything looks good.I am running my model now and it is looking good.
