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?

upload your entire printer.cfg

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
conscious-sapphireOP•2y ago
Ok thanks!
so this is for controller fan #2?
you can name it whatever you want
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?
not unless you want to use a different port or something
conscious-sapphireOP•2y ago
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?
follow the wiring diagram https://os.ratrig.com/assets/files/octopus-11-wiring-full-6a19a1ea9e006b089a71d756741f989d.png
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?
yes
conscious-sapphireOP•2y ago
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?
conscious-sapphireOP•2y ago
yea I was looking at this
so the address of the controller connector is PD12?
for the default controller fan
conscious-sapphireOP•2y ago
teh address of teh contoller fan is PD12?
ok
so adding another fan would be PD13
correct
if you want it to be in slot 4
conscious-sapphireOP•2y ago
ok thanks a lot! Ill try this
copy
thanks! Ill give this a try
conscious-sapphireOP•2y ago
PA? the diagram says PD
doh, you are right
conscious-sapphireOP•2y ago
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)

conscious-sapphireOP•2y ago
its in the user overide section
does not seem to workwhat does this mean exactly? The controller_fan will only turn on in specific conditions
conscious-sapphireOP•2y ago
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
you did put a jumper on the board to select the power right? did you check the wiring to the fan?
conscious-sapphireOP•2y ago
I apologize again
the jumper was not on correctly, its kind of dark and one other pins was not connected
everything works now
thankyou for your help!
