XY zero point, but the object is at the edge of the workspace

Hello,
Normally when i whant the object in the home corner for starting to laser
i do X=0 and Y=0
When i do it now the object is crossing the edge of the machine workspace
en the object reverence looks like its lining from the object middle

in the picture you see the XY are zero, but the allining from the black object is crossing the workspace
