General Mach Discussion / Re: Outputs for Status Lights

Alright so here is what I did to have the red lights on only in emergency mode!!

Set whichever pin you are using (mine was 17) to Active low.

Create a brain as follows:

Normal On (LED) --> Invert flip signal -------------------------------------> Output/Enable (whichever you have associated with you pin)


I don't know why the estop led doesn't work, but i tried a bunch of different ways.  The above configuration has red leds off when mach is in normal mode, and red leds on when mach is in emergency mode.

I also have the brain set up to turn green leds on in normal mode and off in emergency mode.


Hope this helps anyone that needs it!

Okay, its still a no go with the brain.  The green lights are no problem, working perfectly, but when mach is in emergency mode I cannot get it to output an led signal through outputs or enables.  However, when I am in emergency mode, and I hit reset, I get two blinks from the leds.  For some reason, mach does not output an led when in emergency mode.  I'm wondering what other variables are enabled whe mach is only in emergency mode?

Anybody?

I've just been monitoring it on the Mach diagnostics screen.  I will try a physical test as soon as I can.

Wait a minute.  I see a problem.  When I hit the reset button in mach (not an actual e-stop switch) the text to the right says that the estop button is pressed, however, in the diagnostic screen the emergency led does not light up.  I thought that pressing the reset button in mach, had the exact same effect as hitting a physical e-stop button.  Apparently not, any ideas on how to make that true?

I can't even get the enables to work by passing the ESTOP LED to enable 6

that's a good idea.  but still curious.  does mach disable all outputs when in reset mode?

I need Green lights when mach is not in reset (basically when the mach is on in normal mode)  and then red lights when mach is in reset.

Thanks for that.  I can get it to output when it is running, but when I hit the e-stop button, I don't get anything.  Does the e-stop disable all outputs?  It must. so is there an alternative to using an output?

I was wondering if someone could point me in the right direction.

I am trying to build a status light system with leds, but I am unsure of how to configure mach for this.  I have 2 free output pins (16 and 17).  I want the light bar to show green when mach is in a normal and running state, and I want it to show red when mach is in emergency mode.

Can anyone help me out here?
