Changing fan out from out9 to out5 has no effect

Snippy

; Fans
M950 F0 C"out9" Q500 ; create fan 0 on pin out9 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"out8" Q500 ; create fan 1 on pin out8 and set its frequency
M106 P1 S1 H-1 ; set fan 1 value. Thermostatic control is turned off
M950 F2 C"out7" Q500 ; create fan 2 on pin out7 and set its frequency
M106 P2 S1 H-1 ; set fan 2 value. Thermostatic control is turned off

Trying to run the print cooling fan from Out5, curently set to Out9, when changing whe value from above nothing happens and the fan hooked to Out5 runs contantly at 100%.

What is happening here?

Using a Duet 3 board standalone.

post a picture of your wiring

Wires aint the problem.

alankilian

@Snippy For others it often is the problem, so helpful people are asking how you have the fan wired.

Snippy

In the default setting so fans are running at 12v

The fan im trying to run at Out5 is two https://www.digikey.fi/product-detail/en/109BC12GC7-1/1688-1035-ND/6191751?utm_medium=email&utm_source=oce&utm_campaign=3480_OCE21RT&utm_content=productdetail_FI&utm_cid=1663675&so=67660528&mkt_tok=eyJpIjoiWVdZNVptWmtPRFl4WW1FNCIsInQiOiJZcTZHWWQzZVcwc1RiNncrdnVIbTFnZlZ5WXNENmFKYXoyeWJpSXl4Rlg5TnJyVmtwTkVsVGQ3bzhvb0k5YzZseWdJNkpVcnJ5bFYybGl3SGRSaUR0M2c3MmJtRmZhd1crY1BXcEJJaENwSHZHWVFOUnZtM3F0b2FNaVwvQVZBZmYifQ%3D%3D

Cant set Out5 to be the print cooling fan header

@alankilian wires 2-3mm of the connector housing are covered in a black nylon sock that has a glue, so taking pictures is pointless, its just a back wire, to elaborate its red 12v, back gnd and yellow tach,

1=gnd so black
2=12v
3=tach
4=not connected
near the hot end with duppont connectors the 2nd fan has no tach connected.

if you have connected the fan like that, no wonder its not working

OK, from the Wiki: https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram

"4-pin KK connectors with offset spigot OUT_4 thru OUT_6: these are intended for PWM-controllable fans. The connector fits a standard PC-type 4-pin PWM fan. Alternatively, a 2-pin fan may be connected between the V_OULCn pin (+ve) and the OUT_n_NEG pin (-ve). "

It looks like you should be able to start with two wires connected to your fan going to (BLACK)-> OUT5 and (RED) to V_OUTLC1

Is that how you have it connected?

It seems like you <may> have the fan connected to +12 and GND which will make it run all the time.

I've never used a DUET3 (I have a DUET2) so I may be mistaken here, but this gets a lot of people, so hopefully you've done the same thing others have.

well he said his wiring is not the problem, so

Snippy

@Veti Well it is spinning fine, i just cant controll it in webcontroll.

yes that is because of your wiring

We all assume we know which part of our work is correct, so let's try to remain helpful.

Because LORD KNOWS I've been wrong so many times on forums where I'm asking for help I should get spanked.

Veti

that is why i asked for a picture so i can be sure that his wiring is incorrect

@Snippy

Try this and see if it works for you.

Snippy

@alankilian Still running at 100% cant controll it from webcontroll.

Snippy

And i cant run it from Out7-9 since fans in Out8-9 are 24v.

Snippy

@Veti it is correct...

Snippy

Got it to work, now the broblem is that the fans stop spinning at 70% in webcontroll, full blast at 100% and about 50% speed when set to 94% in webcontroll.

so what was wrong?

the fans stop spinning at 70% in webcontroll, full blast at 100% and about 50%

try adjusting the frequency q.

try 10 , 50, 5000 25000

Snippy

@Veti no idea, did the old ''have you tried turning it on and off again'' for about 5 times and told the printer i will build a new one so i think the tea and bisquits chip in the duet started to listen.
