Easel not allowing position change

Wondering if something has changed recently, I’m not able to change work position from lower left to center using the position buttons. the display shows x & y pos. correctly but image does not move. tried carving and machine responding as if no change was made. any ideas?

robert, thanks for your reply. I will try what you suggest . I’ve used the center point as zero on past projects, but so far today I can not get the carve to start at the center of workpiece. love having such a valuable resource available. thanks to you other forum members who are always willing to help.
