This equation will take care of your positive z's. Took a bit to figure out the right language as my base in code is java and things of that nature: ppeck$ # Canned Peck Drill Cycle if depth$ < 0, depth$ = zr$ + depth$ * -1. n$, *sgdrill, *x$, *y$, *depth$, peck1$, peck2$, dwell$, *frplunge$,e$ This will take any take any (-) depths make them positive and the zr$ has to be added on BOSS8 to take in account the feed plane distance when drilling cycles are used. I started with a boss9 post from v9 of mastercam. Thought it would be easier but there are some serious differences. To remove the R and the Q you need to edit the variable to reflect whatever letter your control reads for dwell and remove any reference to Q (example): fmt P 1 dwell$ fmt Z 1 peck1$ fmt Z 1 peck2$ what BOSS8 uses. Seems yours might be same or similar.
