How to connect a second controller fan on Octopus Pro?
I want to connect a second two wire 12 Volt controller fan.
I could just parallel it off the existing contoller fan but as I have fan0 and Fan3 ports free it seems more convenient to use one of these fan ports.
Where do I make the change in RatOS to enable fan3 port to work in parallel with fan2?

Should be as simple as adding to your printer.cfg something like
Where
<name of pin> is the name of fan3 or fan2 port pin that you get from the octopus manualI am guessing that would over right the Controller_fan pin set in RatOS for the first fan?
...well it worked exactly as you suggested!
Many thanks.
Nope, unless you use the exact same name for the fan controller. That's
my_controller_fan in the example above. As long as that is unique, it will add it as a separate fan instead of override itOnce again thanks for your help.
