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
[controller_fan controller_fan2]
pin: PA10
[controller_fan controller_fan2]
pin: PA10
that second part is just a name and needs to be unique otherwise you overwrite the previous definition

Ok thanks! so this is for controller fan #2?
blacksmithforlife
you can name it whatever you want
[controller_fan <YOUR NAME FOR THE FAN>]
pin: PA10
[controller_fan <YOUR NAME FOR THE FAN>]
pin: PA10
but if you use a name that already exists, then you override the previous settings make sense?

Do I need to do an override to get the default to work?
blacksmithforlife
not unless you want to use a different port or something

ok I understand the overide now. but for somereason I cannot get the default to work either can you tell what port the default is set to?
blacksmithforlife
as long as you plug in the first controller fan to that port it will work. Controller fans only turn on when needed

yea I got that set up 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
yes

ok copy 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?

yea I was looking at this so the address of the controller connector is PD12?
blacksmithforlife
for the default controller fan
extended-salmon

teh address of teh contoller fan is PD12? ok so adding another fan would be PD13
blacksmithforlife

yea thats where I was getting confused ok cool thanks! Ill try this really appreciate it so it helps if I have the jumper installed doh! 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? [controller_fan controller_fan2] pin: PD13 does not seem to work

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

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

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 Controller fan 1, the default fan works fine it comes on when things are heating up I would like controller fan 2 to come on at the same time it does not come on, no light on the board when the default fan comes on
blacksmithforlife
you did put a jumper on the board to select the power right? did you check the wiring to the fan?
