Reason for the twin ballscrews is to prevent the gantry from twisting as it moves backwards & forwards.
There is the american standard the english standard and the european standard, I just Clasify them as they are said, X-Y-Z X is connected to Y and Y is connected to Z On gantry mills But my Boxford is a moving Bed from left to right so that is Y is connected to X and X is connected to Z.. That will throw a spanner in the works LOL
