First, I'll bet you have X backlash set to -.0077 user units. I don't think
a
MINUS backlash setting has any valid meaning. Also, I think
you are showing absolute machine position rather than relative
(workpiece coordinate) position.

Check your ini file for the first BACKLASH = line, and see what is there.
