I need to configure the axis movement directions and machine coordinates, I have attached a image diagram of how I need the machine to move but I am struggling with the many settings.

Controller im using is the AXBB and the software is UCCNC.

I need my axis's to move as follows:

Home Switch Positions;

Y = Back, furthest away from front of machine

X = Left

Z = Top

Machine coordinates I need to be set when homed;

Y Back = 1500 - Front = 0

X Left = 0 - Right = 1500

Z Top = 130 - Bottom = 0

Your help with this will be greatly appreciated

You can setup the direction signals one way and then test the axis, if it moves backwards compared to how you want it to work then invert the Active low setting of the DIR signal in the axis settings and press Apply Settings buttons, that will invert the axis direction.
You can do this with all 3 axes and then you will have the coordinate system as you like.
