Stepper Motor Installation Location

Hello, I was just wondering where exactly my stepper motors should go. I have an Elite Foreman and my 3 stepper motors are labeled with stickers on the bottom Y1, B1, and X2. I assume X2 should go on the right side of the x-rail. Should Y1 be on the back left side of the machine and should B1be on the back right of the machine? Or does it matter?

It really doesn’t matter, but y1 is left and b is right
