Which with a reversed 5 volt supply doubly guarantees it won't work. Since it also has a half mic tantalum cap across the power pins, which was the ony thing being powered at its native polarity, so I'm starting from scratch since the pin half of the plug ejected the pin while unsoldering every thing else, so a new 3 pin socket is sitting in a thin puddle of jbweld in the toaster oven at around 145F to hasten the cure. After skimming off the die fins etc and washing it down with acetone for better adhesion of course. hour or so ought to stick it, then glue on another ATS667, put the heat on it for another hour and finish the wireing starting with tradeing ground and 5 volts on the cable coming to it. And maybe I can test it yet today. If I don't screw it up again... One thing is for sure though, I can't net the command-deriv to joint-vel, its instant following error. Joint never moves, but will move in that direction at a good clip after being reset and re-enabled, so its the backlash move that triggers it. the following error occurs when an axis is reversed. But thats a different problem for another day and thread. > Jon > > > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
