Ok, i need to do some serious research to see if that controller can handle that, i know it provides for 4 Axis but im not sure if the 4th can be setup as Dual Axis.

So i know i keep banging on about the weight distribution of the Gantry, but i really am being stupid today. It seems at some point i had lost all of the material properties for my assembly parts, ive just spent a little while going through and properly setting the weights of each component, i have based the Aluminium Plates on being a 6061 Alloy, whether or not this will be the material the plates are cut from i dont know, but it was the most common material so i though i would go with that, i re rain the analysis and it has given me a hopefully accurate Centre of Mass for the gantry, indicated by the Red Dot, im hoping this is a pretty acceptable balance and wont cause any undue wear or stress to the linear bearings:
