| This is why Bridgeport was forced to upgrade these machines with a Z motor encoder as vibration could cause the Z axis to misread and reposition itself. The Z axis is relying on a linear scale that is over 10 years old for positioning. Make sure nothing is loose on the scale and reader head. Also check frequently the nose piece. These would come loose and even break regularly. George
