@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.

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.

Yes I know and by the way I am now using Ultimaker Cura Enterprise 4.10.0 and it works very well.It solved many problems
but I needed that it is activated in that way because I need it so also for other reasons

[paolozampini1973]

@oliof Anyway I did as you told me and it doesn't work I did copy-paste it doesn't work

[Phaedrux]

Have you come around to the idea of using a thermostatically controlled fan tied to a heater active during the print yet?

If that is truly unacceptable, it's possible to use daemon.g and a conditional gcode block to enable fan 5 when the machine state is processing.

[oliof]

@paolozampini1973 I am not sure that you can use enable to get the trigger. I assumed you wanted to turn on the fan manually with a switch since that is how you use pins usually. You have now clarified that, and my proposed solution is not applicable to your issue.

Anyway, I am running out of time for tonight and may revisit this topic later.

[paolozampini1973]

@oliof Ok thanks Okay we'll go back when you can

Obviously making you start a thermostated fan is much simpler but for me it is not enough practically not good

[Phaedrux]

If you're concerned about the motor temp, why not add a thermistor to the motor itself and use that as the source of thermostatic control.

But I have to question the premise entirely at this point, is the motor temperature really a concern?

Yes, of course the engine temperature is a problem
I just don't want to leave them on all the time because now they always stay on you are right I could also put a thermocouple in them which would be simpler

Then adding a 10 cent thermistor to allow for thermostatic control is a good option.

@dc42

would like to enable fan F5 when PIN 17 is enabled and disable fan when PIN 17 is disabled ?

[paolozampini1973]

@oliof Good morning There is a possibility that we will resume the speech of the fins 17 To enable the fan and disable the fan I remember you told me that the time was up and we would talk about it later

[dc42]

@paolozampini1973 what do you mean by "pin 17" ?

Thank you for answering me I wasn't hoping for it anymore I have been trying to talk to her for a long time.

axis Y external DRIVER 7 ( WHEN switch to mode ON PIN17 = EN + 3.3V switch to mode ON FAN 5
WHEN switch to mode OFF PIN 17 = EN + 0.0V switch to mode OFF FAN 5 )
axis X external DRIVER 8 ( WHEN switch to mode ON PIN 22 = EN + 3.3V switch to mode ON FAN 6
WHEN switch to mode OFF PIN 22 = EN + 0.0V switch to mode OFF FAN 6 )
I want to specify that the dwelling of the X and Y motor and the disabling of the x & y motor works perfectly at the beginning Print skills and x & y motors at the end of the print disables the X and Y motors this function works perfectly
