I have been using motion.enable as an output pin to soft start the spindles psu as its input filter is enough microfarads to trip a 25 amp circuit breaker if switched cold, for several years using two timers to fire a pair of 40 amp crydoms to enable it, first thru a 50 ohm 200 watt R that is shorted 3 secs later by the 2nd timer going true. But the only input is the F2 key that toggles it. But as a shutdown its also toggled off by a following error anyplace. I've no clue how thats coupled but it just works. And I can run on a 20 amp circuit breaker with no false trips, staying within the NEC for a 10 gage circuit. > _______________________________________________ > 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.
