[FluidNC Issue#1503] Feature: toggle signal activating push button switch

#1 – bdring 于 2025-05-19

It would be helpful if you described what you are trying to do and why.

I don’t know what those “macros” are. We do not support M100, M101, M200, M201.

Our macros are written in gcode and gcode expressions. Toggling a pin is done with M62 and M63.

Could what you are trying to do be done in a CAM postprocessor? What CAM are you using?

#2 – Abdelrahman22a 于 2025-05-20

I’m not into the CAM phase yet
I’m still trying to figure the custom prop I have
it’s water jet… it takes a 300ms toggle to start and and another one to stop by a Normal Open relay
and when it starts… it takes around 5~10 seconds to build the pressure before the pressure is suitable to perform the Gcode cutting

so I need to assign a macros function that makes a 300msec toggle function with a 10 seconds afterwards
and another one that makes the same thing without the 10 seconds delay
now I’m using the config file 3axis_v3.yaml and it’s working fine
if you can help on how to edit it or assign the spool to it or what ever
and thank you very much for your assistance

You can read all about macros here.

http://wiki.fluidnc.com/en/config/macros

here is an example

M62 P0 ; turn on digital output 0
G4 P0.3 ; wait 300ms
M63 P0 ; turn off digital output 0
M62 P1 ; turn on digital output 1
G4 P10 ; wait 10s

You could put the macro in the config file, or on an SD card.

Most people would do this via a CAM preprocessor. This would add the gcodes into all the the file that are produced. This removes the manual operations.

#4 – Abdelrahman22a 于 2025-05-20

And how can I assign the output pin for these macros?

#6 – Abdelrahman22a 于 2025-05-21

can you tell me please how can I define it and call it as a function?
as I’ll be having couple of other similar function?

M62 P0 ; turn on digital output 0
G4 P0.3 ; wait 300ms
M63 P0 ; turn off digital output 0
M62 P1 ; turn on digital output 1
G4 P10 ; wait 10s

You can store gcode files on an SD card or the local file system (localfs). You can run them by sending $SD/run=.

Please search the wiki for “macro”

#8 – Abdelrahman22a 于 2025-05-21

Please, check what I’m writing, you might get an idea of what I mean

#9 – bdring 于 2025-05-21

Did an AI suggest this? It is not even close to the FluidNC file format.

#10 – Abdelrahman22a 于 2025-05-21

Yes, I’m working with AI to write it as I don’t have enough knowledge
I really appreciate the help

#11 – bdring 于 2025-05-21

The AI is clueless. What you posted is gibberish. Not even close. Read the wiki.

If you have questions, please point the the exact wiki section that you don’t understand.

#12 – Abdelrahman22a 于 2025-05-21

I’ve solved it, thank you so much
The only issue I’m facing now is hard resetting
I need to configure it
and none of these are working

#13 – bdring 于 2025-05-21

Search the wiki for “ignored key”

#14 – Abdelrahman22a 于 2025-05-22

I’ve read it and the code itself doesn’t have any of the reasons to ignore these keys

I’ve managed to make the macros work

to make the picture clear for you
I need to assign a pin on the ESP32 in a way that when it receives a certain input (either high or low) it stops everything immediately
just as the reset button on the interface itself do stop everything and activates the alarm…. but from a hardware signal and with an extra macro line if possible

#15 – bdring 于 2025-05-22

Post your current config file.

#16 – Abdelrahman22a 于 2025-05-22

I need macro2 to be executed upon receiving the hardware signal
and macro3 to be executed when the hardware signal that signal is removed

Can you upload it as a file instead (drag and drop it to github), the indentation is wrong in what you posted.

#18 – Abdelrahman22a 于 2025-05-22

I’m trying but it’s not allowed

#19 – breiler 于 2025-05-22

Try renaming it to .txt

#20 – bdring 于 2025-05-22

I edited it to add a code section

#23 – MitchBradley 于 2025-05-22

Two problems:
1. You need to separate the individual commands inside the macros with &, like this:

macros:
   macro0: M64 P0 & G4 P0.3 & M65 P0 & G4 10.0  

2. You have not assigned any pins to invoke the macros

control:
  ...
  macro0pin: NOPIN

NOPIN needs to be replaced with some input pin like gpio.SOMEPIN_NUMBER.low

> I need macro2 to be executed upon receiving the hardware signal and macro3 to be executed when the hardware signal that signal is removed

FluidNC does not have a way to do that. It executes a macro only when a button is pressed. It cannot execute one macro on press and another on release.

#25 – Abdelrahman22a 于 2025-05-22

> Send a photo of your electronics
it should be like this
connected to 3.3v or GND depending on the definition one each pin normal state
and then it executes the sequence (macro2 or 3) upon changing the switch state

!Image

#26 – bdring 于 2025-05-22

Use a switch with both N.C. and N.O. contacts and connect to 2 input pins.. Currently FluidNC only supports one active state or action per input.

Good luck with your project. At this point I have given as much free support to a special project. I am going to step away from this issue.
