To me though it seems logical that the bed should be X, Gantry Y and of course spindle Z, wouldn't surprise me if the Americans fucked everything up as they don't even know how to spell colour lol.
In a moving gantry, yes... well... maybe...

I still think it is more logical the way I see it.

The axis parallel with your belly is the X. Positive X movement is from left to right.
The axis moving away from you is the Y. Positive Y is movement is from you, negative is towards you.

This seems to work with every CAD, CAM software as well as Mach3 and UCCNC screens I used.
