Beat me to it Neale lol, my 3d printer had the X&Y axis wrongly configured for years and I never noticed because being square it just printed everything at 90° from day 1 and with no reference point I never clicked lol.

Logically the lowest axis should be X going up from there just goes against common sense to have the Y axis as the lowest one lol.

On a milling machine things are more confusing I think we should rename the Axis Curly, Larry and Moe instead ;)
