I guess I still need some help here is an example right out of one of my programs that we are using right now in order to set several z heights on the same part for engraving.

I just learned about the protected probe move code today. But am I supposed to write my own Sub Program and write the logic statement inside of that or do I write the logic statement directly in the main program? If you run a single surface probing cycle all you have to do is write G65 P9023 A9. S154.01 and hit cycle start with the probe within .400 above the surface you are probing but then its actually running a 9000 protected program and has the logic statement inside of it. As of right now this is what I have as a program. The question mark is where I get confused GOO G40 G80 G91 G28 ZO G103 P1 T25 M06 G65 P9832 G43 H25 G00 G90 G54 XO YO G65 P9810 Z1.25 F200.

Machine guy, I did a search before I wrote this and did see your post but I don't have a bore to probe its simply a solid surface.. I've used probing on a bore before on every part in order to maintain concentricity on the bolt patern I was putting on the part and it works really well . I think cncchip makers post is exactly what I am looking for. Let me go out to the machine and try that code out ill let you know soon if I get it to work. Thanks

I have been running forged AR15 lower receivers for a few years now and we have always segregated the parts by thickness in groups of a .003 total tolerance. We would then set up the machine to run a certain lot size then move our work offset up in z for the two vice ops and over in x for the indexer op. Since our program is based off of centerline and we have probing capabilities I know there is a way to have a known z location (bottom of fixture parts rest on ) and a known x location (side of fixture in the indexer the part bolts to) then we can probe top of part in the vice and take the middle between the known z and our new probed z and make that our Z work offset and same thing goes for the X on the indexer. I just don't know how to properly code a probing cycle to do just that. I have used the probing cycles that the has machines spit out when you want to pick up work offsets but there is nothing for centerline on a known z to a new probed z or x. I've also looked at renishaws probing cycle book and it all just seems jibberish to me.
