That's why I find this whole front/side business confusing - should that have said when gantry is running front to back, that is, left to right? I call the long side of my machine the front because that is where I stand to use it. Doubt if it makes sense to anyone else, as it's because of the layout of my workshop. But I strongly agree that it's just a matter of preference, and what is absolutely vital is that x0,y0 is at the lh corner nearest you, so the bed looks just like the virtual sheet of paper you draw on in your CAD programme. If you don't, you are going to confuse yourself every time you try to set up a new piece of work. I've ended up with x0,y0 at the far right-hand corner of my 3D printer and I get mildly baffled every time I use it. I should just turn it through 180 deg, but I'm too lazy to shunt everything around to do it.
