The spacing on the GT2 belts is between the belt grooves. The rubber teeth on the belt add to the radius of the belt, causing the effective circumference of the large pulley to be larger. This was a problem on the icepick delta, throwing of print dimensions until I added these configuration options.
Not sure if you already factored this in with the pulley radius, in which case this addition maybe unnecessary.
