Info on Connecting two Controller Fans, octopus 1.1

Im having some problems figuring out how to connect two additional controller fans to my octopus. My part fan and extruder fan are connecter per the ratrig instructions. I am assuming I can use the next two connections but can't seem to get them to work with the config overides. Do I need to mod the firmware?

ohh, you are just overwriting the default controller fan. You want

that second part is just a name and needs to be unique otherwise you overwrite the previous definition

near-sapphireOP•4/5/23, 6:04 PM

Ok thanks!

near-sapphireOP•4/5/23, 6:04 PM

so this is for controller fan #2?

blacksmithforlife•4/5/23, 6:04 PM

you can name it whatever you want

blacksmithforlife•4/5/23, 6:04 PM

blacksmithforlife•4/5/23, 6:05 PM

but if you use a name that already exists, then you override the previous settings

blacksmithforlife•4/5/23, 6:05 PM

make sense?

near-sapphireOP•4/5/23, 6:05 PM

Do I need to do an override to get the default to work?

blacksmithforlife•4/5/23, 6:05 PM

not unless you want to use a different port or something

near-sapphireOP•4/5/23, 6:06 PM

ok I understand the overide now. but for somereason I cannot get the default to work either

near-sapphireOP•4/5/23, 6:07 PM

can you tell what port the default is set to?

JJudeLabs can you tell what port the default is set to?

follow the wiring diagram https://os.ratrig.com/assets/files/octopus-11-wiring-full-6a19a1ea9e006b089a71d756741f989d.png

blacksmithforlife•4/5/23, 6:08 PM

as long as you plug in the first controller fan to that port it will work. Controller fans only turn on when needed

near-sapphireOP•4/5/23, 6:08 PM

yea I got that set up

near-sapphireOP•4/5/23, 6:08 PM

so what you are saying is that if I have the controller fan hooked up to the 3rd port there it should be working by default?

blacksmithforlife•4/5/23, 6:08 PM

yes

near-sapphireOP•4/5/23, 6:08 PM

ok copy

near-sapphireOP•4/5/23, 6:09 PM

one thing is that I could not find the map of the port to the ID, for example PA9/ PA 10 etc.. do you know where I can find something that maps the diagram to the address?

near-sapphireOP•4/5/23, 6:10 PM

yea I was looking at this

near-sapphireOP•4/5/23, 6:11 PM

so the address of the controller connector is PD12?

blacksmithforlife•4/5/23, 6:11 PM

for the default controller fan

near-sapphireOP•4/5/23, 6:11 PM

teh address of teh contoller fan is PD12?

near-sapphireOP•4/5/23, 6:11 PM

so adding another fan would be PD13

blacksmithforlife•4/5/23, 6:11 PM

correct

blacksmithforlife•4/5/23, 6:11 PM

if you want it to be in slot 4

near-sapphireOP•4/5/23, 6:11 PM

ok thanks a lot! Ill try this

near-sapphireOP•4/5/23, 6:12 PM

copy

near-sapphireOP•4/5/23, 6:12 PM

thanks! Ill give this a try

blacksmithforlife•4/5/23, 6:12 PM

near-sapphireOP•4/5/23, 6:12 PM

PA? the diagram says PD

blacksmithforlife•4/5/23, 6:13 PM

doh, you are right

near-sapphireOP•4/5/23, 6:13 PM

yea thats where I was getting confused

near-sapphireOP•4/5/23, 6:13 PM

ok cool thanks! Ill try this really appreciate it

near-sapphireOP•4/5/23, 6:27 PM

so it helps if I have the jumper installed

near-sapphireOP•4/5/23, 6:27 PM

doh!

near-sapphireOP•4/5/23, 6:29 PM

so I do have one more question. It looks like the default controller fan is working. But what do I do if I want to install a second controller fan? at PD13?

near-sapphireOP•4/5/23, 6:29 PM

[controller_fan controller_fan2]
pin: PD13

near-sapphireOP•4/5/23, 6:29 PM

does not seem to work

blacksmithforlife•4/5/23, 6:35 PM

upload your printer.cfg (it matters where you put that information)

near-sapphireOP•4/5/23, 7:11 PM

its in the user overide section

blacksmithforlife•4/5/23, 8:07 PM

does not seem to work

what does this mean exactly? The controller_fan will only turn on in specific conditions

near-sapphireOP•4/5/23, 8:09 PM

My setup has two controller fans. I build a fane frame that goes on the outside of the octo and it has two 60mm fans on it which are over the motor controllers

near-sapphireOP•4/5/23, 8:09 PM

Controller fan 1, the default fan works fine

near-sapphireOP•4/5/23, 8:09 PM

it comes on when things are heating up

near-sapphireOP•4/5/23, 8:09 PM

I would like controller fan 2 to come on at the same time
