How do you locate an exact spot on the work area?

I have discovered that Easel uses machine zero as start position. That means that even though you set XY zero at the corner of the workplace it will never use it as such.
Say you want a 10x10 work area and you place 1 7x7 blank and set XY zero at the lower left corner.
Push go and it will start way off the mark 100% of the time.
It ignores actual xy zero.
I just found the puzzle maker and thought ‘what a great idea’ and proceed to use it. Printed a picture, glued it to a 7X7 piece of 1/16 birch ply. Taped it to a waste board, set the xyz zero at the corner of the picture.
First corner piece was just about center of the 7X7 work area. Ruined the work.
So my question is why bother setting XY zero if the Easel ignores it?
