I have accidentally touched off the wrong axis before, and I agree that it is very frustrating. But I don't blame the software. Sure, it might be _convenient_ for the touch-off dialog to default to whatever axis was moved last. But that is only a convenience. For example, suppose I'm trying to get a lathe tool touched off. I might use jogging or MDI to take a light cut, then jog (or MDI) the Z axis to get the tool clear _without_ moving X. Then I can get out the micrometer, measure the diameter I just cut, and touch off X accordingly. Note that I moved Z last but want to touch off X.... After accidentally touching off the wrong axis once or twice I learned that it is MY JOB to make sure I'm touching off the right axis. The software can't read my mind. Sure, I _often_ want to touch off the last axis I moved, but not _always_ -- John Kasunich [email protected] ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
