Can you set external triggers to toggle gcode?

Yeah I've been reading that already. That's fine for setting a state with a single button... Like an end atop or emergency stop. But I would like the ability to cycle through two states or more.

Is there any kind of expression system that can be used?

I have a dynamic button on my Duet, for one example, when a print starts, it is configured for trigger6

trigger6 contains a command for pause

pause contains a command to reconfigure the button for trigger7

trigger7 contains a command for resume

resume contains a command to reconfigure the button for trigger6

etc etc

should be easy to do it for LED stuff

Actually that sounds reasonable.... Thanks

Ok having a problem...

At the end of my config file I have

M106 P1 S1 ;Turns lights full bright
M581 T2 E3 S0 ;Light switch

trigger2.g
M106 P1 S0.66 ;Turns lights 1/3down
M581 T3 E3 S0 ;preps next trigger

trigger3.g
M106 P1 S0.33 ;Turns lights 2/3down
M581 T4 E3 S0 ;preps next trigger

trigger4.g
M106 P1 S0.0 ;Turns lights off
M581 T5 E3 S0 ;preps next trigger

trigger5.g
M106 P1 S1 ;Turns lights Full on
M581 T2 E3 S0 ;preps next trigger

The lights will cycle down once and back to full bright as the button is pressed. But trigger5, the prep next trigger doesnt seem to work.

So i press the button from fresh restart, turns down 1/3 press again turns down another 1/3 press once more turns off, press again and turns on full bright, but pressing again does nothing. The lights would briefly flash off but isnt cycling down again.

Am i missing something?

When you create a new trigger to do something different next time the button is pressed, you should cancel the old one unless you want both trigger files to be run.

@dc42 Oh how do you cancel the old one?
I had assuming the new trigger declaration would over write the old one...

Read the documentation for M581 on the GCodes wiki page.

I have read the docs and maybe I'm blind I can't see anything about canceling the previous trigger?

use S-1 to disable a trigger file

Mangy_Dog

Thanks
s-1 wasnt listed on the doku gcode wiki... the reprap gcode wiki did mention it but as a delete all triggers option...

Anyway its sorted now thanks

From the doku wiki:

Using S-1 with no X Y Z or E parameters sets the trigger back to ignoring all inputs.
