On my lathe I have designated T1 (WNMG turning / facing tool) as the "Master" tool. This tool always has X=0 Y=0 in the tool table. I then touch-off the work with this tool (generally making a test cut and measuring the result for diameter). This touch-off goes into G54 (or whatever, though I very rarely use the others) The, all the other tool offsets in the tool table are relative to that tool. (and may be tweaked based on test-cuts) The G54 X should hardly ever change, but the G54 Z is re-set for every job to be the right-hand end of the work. If you had a toolpost-mounted probe then that could be the master tool. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
