Perhaps you can share the solution that Oliof was so kind to provide and perhaps we can explain it.

oliof
M581 T1 P17 S0 defines trigger 1
then you need a macro called trigger1.g
In that Macro you do M106 P5 S0
M581 T0 P17 S1 defines trigger 0
then you need a macro called trigger0.g
In that Macro you do M106 P5 S255

That seems pretty straightforward.

M581 T1 P17 S0
M581 T0 P17 S1

would need to go in config.g

Then create two macro files in the sys folder: trigger1.g and trigger0.g
Those are just text files and you can create them in the web interface or on your computer and upload them. Put the M106 commands into those trigger macros respectively.

trigger0.g trigger1.g

I did but it doesn't work I don't understand why

@paolozampini1973 as I wrote in chat, define triggers using M581 and put the fan control commands in the corresponding trigger macros.

Could you please tell me the explanation I don't know where to get the macros are created How to do it I don't understand I hope not to bother you too much

@paolozampini1973

The M581 commands need to go into config.g

trigger0.g needs to have

M106 P5 S255

as its content

trigger1.g needs to have

M106 P5 S0

as its content

trigger0.g trigger1.g config (31).g
You can see if that's as good as I did

oliof

Your trigger files do not have the M106 commands as their content.

Please can you correct me the files I posted I don't want you to spend a lot of time

oliof

@paolozampini1973 Add the following two lines at the end of config.g:

M581 T1 P17 S0
M581 T0 P17 S1

put the following into the file /sys/trigger0.g and nothing else

M106 P5 S255

put the following into the file /sys/trigger1.g and nothing else

M106 P5 S0

Also, I am assuming you are using a toggle switch like this:

No I'm not using this SWITCH But what does it have to do with it

oliof

@paolozampini1973 what kind of switch do you use? show me a photo. A toggle switch with two positions will work with my example. If you use a momentary / push button switch it will not work like that, another solution is required.

AC 17

oliof

@paolozampini1973 that kind of switch should work with the solution I provided.

But I surely do hope that you are NOT connecting high voltage to the pins!! That would blow up the board.

paolozampini1973

@oliof So the talk is this I have to activate a fan When activating the x axis and the if Y with the external drivers that I connected EN + EN- when enabled Enables also the fan for as long as notified EN + and when EN- is Disable we will also need the fan but honestly the switch has absolutely nothing to do with it Maybe I didn't explain myself

However I did copy and paste and the fan does not turn on

paolozampini1973

@oliof EN + EN- now they are fully functional. When it starts printing the motors go to on mode at the end of the print they go to unit off and work very well the cooling fan for the engine must also work in the same way

oliof

@paolozampini1973 So you want to start the fan when a print starts, and stop it when the print is finished? Then you can put the M106 P5 ... commands into your start gcode and end gcode in your slicer.

No need to use pins and triggers.

No need to use pins and triggers.

but in this way if I go to make six prints in 30 minutes each time I have to insert it in the GCODE and so it becomes very cumbersome

paolozampini1973

@oliof Anyway I did what you wrote to me and the fan doesn't work it always stays off When the print started or I move the axis manually

oliof

@paolozampini1973 every slicer allows you to define custom start and end gcode that is added to the file automatically during slicing.

That is where you can add the commands to start and stop the fan. You set it up one time, it automatically gets added to the file.
