I followed an older post about switching the router on/off within the Gcode. I have a SSR hooked to pin 27 (mist) output on the board. It is functioning but requires using the M7 (on) and M9 (off) commands. Normally the M3/M5 Command would be used for this function. Is there a way to configure the board to switch an output pin using the M3/M5 command? Currently the M3 does not turn on any LEDs on the board.
I have not tried it, but you might look at the “Relay” section of the FluidNC Wiki “Spindle” page.
My config for relay is:-
Relay:
direction_pin: NO_PIN
output_pin: gpio.2
enable_pin: NO_PIN
disable_with_s0: false
s0_with_disable: true
spinup_ms: 2000
spindown_ms: 2000
tool_num: 0
speed_map: 0=0.00% 1000=100.00%
off_on_alarm: false
atc: atc_manual
m6_macro:
Make sure you set the correct output pin.
Does the M3 command start your spindle? The gpio .2 pin is configured for coolant on my board. The M8 Command turns on that PIN
My SSR is wired up to that pin so yeh.
I’m already using gpio.27 for laser so used gpio.2 as I don’t use coolant. There’s no hard and fast rule as to what pins to use for which function.
Did you add this to the config.yml file?
This change alone might not work with the rest of your config. Make sure you don’t already have a relay: section and also make sure that the pin you are using is not utilized anywhere else.
For instance the default config for thed Lowrider has:-
coolant:
flood_pin: gpio.2
mist_pin: gpio.16
delay_ms: 0
As I don’t use coolant, to free up the pins I have:-
coolant:
flood_pin: NO_PIN
mist_pin: NO_PIN
delay_ms: 0
Does that make sense?
Yes makes sense. I’ve tried you advise, but when i add the relay: code I get an error. Is there a specific spot in the config to place the code?
What error are you getting? Do you want to paste the config?
You can’t just drop it in the middle of another bit of config. I guess I deal with yaml most days with work so I take it for granted but ideally should be in a section on it’s own and there just be one relay: section.
Do you know what version of fluidnc you are running?
Sure, thanks! When I get home from work I’ll post mine.
Here it is, the error message is “Undefined:” i’m using version 3.7.17. I only have the error when I added the relay:

When you quote your config.yaml, it needs to be preformatted (the icon that is </> on the edit toolbar).
Can you edit your post, delete all of the config.yaml, use preformatted, and then re-paste your config.yaml?
What’s in there now masks and obscures a bunch of the formatting we care about.

YAML files are very particular about spacing. Those lines need to be like this. I’m not sure it’s case sensitive, but I’d change that as well:
relay:
direction_pin: NO_PIN
output_pin: gpio.2
enable_pin: NO_PIN
disable_with_s0: false
s0_with_disable: true
spinup_ms: 2000
spindown_ms: 2000
tool_num: 0
speed_map: 0=0.00% 1000=100.00%
off_on_alarm: false
atc: atc_manual
I spaced every thing as you suggested and replaced the capital w/ lowercase but I still am having the same error.
Can you provide all the text around the error? That doesn’t tell me much by itself.
I’d also try getting rid of that “atc: atc_manual” line. The FluidNC wiki page doesn’t show that as an option for a relay and you’re not using an ATC. I’m also not sure if that exists in 3.7.17.

What is the output of $SS?
Removing the “atc: atc_manual” line solved the problem. Thank you for the help
