There is a thread on here about them do a search. I run 2 vf4's and a vf11 all with the probes.. I love them!!. to get to the macro's to use the probe go into a program hit edit then program conversion three times then hit f2 this will bring up a menu scroll down to 9996 hit write/enter and you can look at the probing macros and use them, if I remember it I can bring home the papers that come with the probe and send them to you. But there is not much there to read I think its about three or four pages. I just started using them without reading anything, they are mostly self explanitory once you select one, just read the screen and it will tell you where you need to be with the probe in relation to the part. This is assuming the probe is properly calibrated.
