@grizewald
Hey thanks for that. I’m not at the printer till tomorrow now but I will defiantly try a few of those settings.
Keep my fingers crossed as I've spent hours trying to solve it.
I'll let you know how it goes.

@deckingman Much appreciated. Looks like i will stick to the 16.

OK, long story short, I tried to go to the 2.05 first but had the same error. Then I copied the missing file "Duet2CombinedIAP.bin" from the v 3.00 and put it into the /sys file on the SD card. Hey hit the money, all the upgrades went as they should.

Holy Cow!! How backward can I be. My wires are connected to the endstop. Thanks for the picture, with out it I would have been convinced we where talking about the same thing.
I've just redone it now and started the mess. Looks like its working.
Many Many thanks. You've been a huge help.

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

B3950

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????
