But it is probably unwise to rely 100% on either, so the e-stop loop should have hardware effects too. I have generally considered the iocontrol parts of the e-stop loop as mainly to allow a soft-estop and to let the controller know when e-stop has been hit. I agree, neither the docs nor the code give much clue what the pin is intended for. -- 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
