I've given some thought to a 6 tool carousel hanging on the post, with a double ended transfer carrier, but clearances are a major problem for the transfer carrier, and making it even more complex to control if single ended. And that involves controlling a racheting drill driver to run the drawbolt in 3 modes, one to tighten, and just loosen and one to fully drop the r8, and that expands to 2 carousels to control or a much bigger carousel, one on each side of the post if 2. Writing sw for that will be painfull, for me at least, and would make me convert from a 5i25 with its 34 pins of limited direction I/O, to a 7i90 and 3 7i42TA's to get enough I/O (72 gpio's not subtracting whats used for 7 canned functions to do it. Sigh. Not to mention the current tool.tbl format has no place for such changer data tomfoolery. The end result is that it very likely will never happen. LCNC maybe needs to grow a changer.tbl? I have other stuff that needs doing before I get back to the changer. :( > ---------------------------------------------------------------------- >-------- 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 > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
