How to make a loop of a Output_Pin ON and OFF?

FBG

Hello everybody,

I need to make a thing that I think that is easy but for a newbie as me not...

While I am printing I need that a output pin turn ON during 2 seconds and off 10 seconds, continuously while I am printing
ON 2 seconds
OFF 10 seconds
ON 2 seconds
OFF 10 seconds
...loop... until finish the printing

//
I know how create a PIN output and turn on manually with the code, but not know how to make this "program" and start in loop while the printer is printing...

How I can make this?

Best Regards

@FBG you'll want to use a while loop in daemon.g
https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands#loop
something like

while state.status != "idle"
  M42 P0 S1
  G4 S2
  M42 P0 S0
  G4 S10

edited to swap <> for !=

@jay_s_uk I try but....
Error: Failed to read code from macro daemon.g: Failed to evaluate "state.status <> idle": expected an expression

This is my daemon file:

while state.status <> idle
M42 P5 S1
G4 S2
M42 P5 S0
G4 S10

@FBG you missed the " around idle

@FBG
Compare what you posted with @jay_s_uk 's sample.
You missed the quoted string and have not indented the following code

@FBG also replace <> by !=

@dc42 said in How to make a loop of a Output_Pin ON and OFF?:

@FBG also replace <> by !=

Haha. Missed that! 🧑‍🦯 🤪

Now is working properly!!

Sorry dears, not solved.
I was thinking that is working because don't show error but now say:

Error: Failed to read code from macro daemon.g: empty while loop detected in line 2

My code is:

while state.status  != "idle"
M42 P5 S1
G4 S2
M42 P5 S0
G4 S10

@FBG You haven't indented the code

@FBG said Need to indent the code

My code is:

while state.status  != "idle"
    M42 P5 S1
    G4 S2
    M42 P5 S0
    G4 S10
