One recommendation is to put a Vee cutter in your spindle and run a program where the Vee bit just touches the material in a uniform grid pattern. Take your "part" and measure all the positions from the 0,0. You may have your machine set up in such a manner that it is not just perfect. When I did this, I ended up adjusting the ini file slightly to correct for a 1/8" undershot over my 4' X axis and 1/16" on my 2' Y axis.
