Hello Ray, Have you tried adding the .500 depth value to the .128 drill offsett value and starting from there?And if you want it to clear beyond the .500 as it peck drill change the R value in pecking cycle line. example G98 G83 G1 Z-.5 Q.1R.51F10.;
just make sure that the line before this is G0Z1. then the pecking cycle after this line.
hope this helps out a bit

Good Luck
