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

Re: [Emc-users] Starting up in Machine ON
Hi There…I’m hoping to start in the ‘machine on’ state rather than estop on. After that, yes, I would like to home the axes, then set the mode to MDI and also set G93. I had not asked anything but the machine state as I thought it would be better to take it one step at a time… Thanks very much, Alan Sent from my iPhone > On Dec 18, 2023, at 2:09 PM, Todd Zuercher wrote: > Probably, but we will need a better explanation of exactly what machine > responses you want to what machine inputs, before we could give a detonate > yes or instructions how to do so. > > Are you asking for the machine to automatically home all joints when the > machine power/enable button is pressed? > > Are you asking for a reset button that returns the machine to a ready > position after an incident or interruption of a program? > > Something else entirely? > > Todd Zuercher > P.

Probably, but we will need a better explanation of exactly what machine responses you want to what machine inputs, before we could give a detonate yes or instructions how to do so. Are you asking for the machine to automatically home all joints when the machine power/enable button is pressed? Are you asking for a reset button that returns the machine to a ready position after an incident or interruption of a program? Something else entirely? Todd Zuercher P.

This machine is inaccessible to humans without turning off power, so there is no safety concern. Thanks so much, Alan\ All of my machines are power controlled 100% by the state of the F2 key, by shipping its state out to a breakout pin or 2, which in turn trigger a block of 60 amp 600 volt SSR's that control all power to the machine. By the same idea, any error reported by these new stepper/servo's knocks F2 down from the e-stop circuit that signal is coupled to. Since these stepper/servo closed loop drivers need a power down cycle to recover, this is the first step in recovery from an error. Fix the cause of the error like a wrench left on the table or??? remove the tool or not depending on how it moves to home because it will need rehomed, hit f2 to repower the machine, rehome it and either hit run to carve air, or if feasible, run from line after reinstalling the tool if it was removed to home it safely.
