hello all, i am looking at getting mach 3 and nfs wizzards from nfs just have some questions.  i wached the videos on mach support site and the from them i gather that you are safest working at 25000 hz , but are their any problems working at 35000hz. i am currently using flashcut and love the interface it operates motors at up to 35000hz, but i like the wizzards that you can use with mach.   i would also like to know about touchprobe applications can a macro be set up to touch off a part to find center of exiting hole, or side of a part?

You can run at 35KHz mode no problem. We don't like to have people just setting up if they don't need to have it...
The touch probe can be used for anything that you like... I have set up my probe here to center a circle off 3 points I have also make a wizard that will set the part rotation ... This will make it so you clamp the part down probe and CUT! The probe cycle will skew the coordinate system with coordinate system rotation.

I hope this helps
