Sorry I am an idiot I posted the old config from my duet2. That I had on the desktop. I will update. What a fool.

Thanks got it working by using out 1. Bit bummed I have an always on fan now for the hotend. But thems the breaks

@droftarts Thanks very much. That sorted it.

@droftarts
Ok I thought I tried that. But will try again.
I got that from the example code on the wiki.

M950 J1 C"!io1.in"  ; Input 1 uses io1.in pin, inverted

Revised. Sorry for the cconfusion.

Sorry I am an idiot I posted the old config from my duet2. That I had on the desktop. I will update. What a fool.

I have recently moved across from a duet 2 to a duet 3 mini 5+.
I am trying to setup my hardware buttons to trigger home etc. All were working on the duet 2, but I can't get them to work on the mini 5.
I know it must be me doing something wrong but I can't work out what. I have tried different pins and even just hooking up a end switch to grnd and in pin.
I am currently trying to use io6 but could use other. I have the reset working. So makes me think I am doing something wrong in the Config.g
Any help would be much appreciated.
Thanks Matt.
Revised with the correct config.

Ok so not the pin unfortunately but was worth looking into.
I am still suspecting something wrong with out 2. I hooked up a wire just to the +vout and connected my meter. and earthed of the board and get 24v. As soon as I hook up the fan the voltage drops to about 3v and no fan.
I have tested the fan on a direct 24 v and it works fine and I have also tried another fan.
Does this sound like a board problem?

I am on the last part of getting my toolboard working and everything is great, but I cant get a fan to work on out 2. I am pretty sure I have everything right and it may be faulty. Unfortunattaly I paid $70 or shipping from the US to Australia. So if there is anything wron with it I think I am just goint to have to live with it.
Here is my wiring and my config. I can get the hotend fan to run and if I swap the fans they work. So nothing wrong with the fan.
I am thinking my only optin it to run an adittional set of wires back to the mainboard as sad as that makes me. Would love any suggestions or if anyone can see what I have done wrong.
Thanks Matt

@t3p3tony Could you tell me if you know if any have been sent out to Australian distributors. Thanks Matt

Would some one be able to give me a simple diagram on how to wire a 74HCT08 I am a noob with electronics at this level. I would really appreciate some guidance. I won’t to hook up some neo pixels to a duet wifi. But I have no idea how to use a level shifter. Thanks very much Matt.
