Halui is a program that replicates many of the actions that are otherwise handled in the GUI. http://linuxcnc.org/docs/stable/html/man/man1/halui.1.html In this case you would need to connect up the HAL pin halui.machine.on Does your machine start up in the e-stop active or e-stop inactive state? (This will depend on the wiring of the HAL e-stop loop) If it does then you will also have to toggle the halui.estop.reset pin. (And, having just checked, you can set them both at the same time, it needs to be estop.reset then machine.on) If the machine starts up in e-stop OFF then you probably just need a single line in a postgui halfile setp halui.machine.on 1 If you also need to reset the e-stop then it's a little more involved. So, one way would be to set up a couple of cascaded one-shots in HAL, then trigger them on the postgui halfile. In the main (or custom) HAL: loadrt oneshot names=estop-pulse,machine-on-pulse addf estop-pulse servo-thread addf machine-on-pulse setp estop-pulse.rising 1 setp estop-pulse.falling 0 setp estop-pulse.width 1 setp machine-on-pulse.rising 0 setp machine-on-pulse.falling 1 setp machine-on-pulse.width 1 net e-reset estop-pulse.out => halui.estop.reset => machine-on-pulse.trigger net on-signal machine-on-pulse.out => halui.machine.on Then in the postgui HAL: setp estop-pulse.trigger 1 The idea is that the postgui HAL first triggers a 1-second pulse to estop-reset, then the falling edge of that pulse triggers the machine-on. It would also be possible to trigger machine-on directly from the falling-edge of halui.estop.is-activated, but that would override the normal ui functions (the machine would _always_ turn on when the e-stop was released) and you might not want that. -- 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
