You're a Legend, works like a charm. Thank you so much, it seems simple enough when you see it but I was trying all the wrong way. Much appreciated.

Hi all, I have a small issue that I'm hoping is a quick fix. My fan0 on my duet WIFI 2 is not working(no problem its toast) and i have connected my parts cooling fan to fan1. My g code is messed up as it only works as a hot end tool fan. Comes on as soon as the hot end heats up. The actual hot end fan is connected to a 24 v source an is always on already. The fan control on the screen has no effect on the fan speed. my g-code must be messed up, not sure if i have too free up the default F0 first?? the related g-code I have is below. All i would like is to have the parts cooling fan controlled by the screen fan and working on fan1 pin.
Please help this ignorant brain. Thanks.

M950 F0 C"fan0" Q500 ;new settings ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ;new settings ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
M563 P0 S"Mosquito" D0 H1 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0

Thanks for your help Veti

Thank you I'll type that in.

@Veti said in Fan Control Issue:

find the correct beta value in your thermistor

Evidently my hot end temp sensor
is as follows:
2M NTC 3950 100K Ohm High Temperature Resistance

Could i ask how and what setting to put in to the config.g for this?

Ill go see where it came from. Sorry not a jumper, I meant the connector from the fans that go onto the board.

B4138

Thanks for your help.
Regarding the B4138, i don't have any documentation regarding that. Ive looked through old setups and that's the one that its always used. How could i test this is correct?

Jip, everything now seems to work, I'll replace the connector, it looks OK but somethings off.

Must be like a faulty wiring connection.??

Ok.. so after plugging the jumper into always on then back to pin 1 they are now working????

ok, after changing that the fans still don't come on at all. Ive put the jumper onto always on and the fans con on just fine.

M106 P0 S1

OK ill look into that, but just to confirm its not related to the fan issue?

@Veti
OK, i don't have any issues with the hot end or bed heating up and maintaining temp, not sure i understand the connection with the fans?

Thanks ill go try, the software rebooted the duet, ill try turn in off and on physically now

Thanks, I didn't change the connections and it was working, I'm not sure. The first pin Pin0 failed a while back so if you say the config is ok then I guess i have a failed mosfet. Not sure if that's changeable, I've changed a few on my Arduino board.

The tool fan or hot end fan is always on and i don't want to control that, the parts cooling fan is connected to the pin in the diagram that i circled, and that's the one i want to control. I can not get them to come on at all anymore.

It's not working. Or did I misunderstand and I cant control them??

Ok I'm trying this, hope I understood correctly, I've been through that document but I'm not getting it I guess. Its not through lack of trying

; ##### Fans #####
; =================

M950 F0 C"fan1" Q500 ; create fan 0 and fan1 on pin0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 name and value. Thermostatic control is turned off
;M950 F1 C"Parts Fan" Q500 ; create fan on pin1 and set its frequency
;M106 P1 S1 L41 X255 B1 H1 T45 ; set fan 1 name and value. Thermostatic control is turned on

sorry didnt see that

Thank ok ill delete it. then do i change the other code to
M950 F1 C"fan1" Q500

Its not my field o expertise?
