I have attached the connection diagram from the build instructions I got from MakerFarm.
Using the same terminology this diagrm uses, I currently do not have a Print Cooler running (fan to cool the printed objects). What I have is a Cooling Fan. So, I am not using D9.
I just noticed that the diagram shows Cooling Fans are connected to the lower 12V line, but I have my fan connected to the upper 12V line. At the time I didn't think I would matter, but now I think it may do - like we've been saying, I may have connected my fan to the rail used by the heated bed.
Having said that, I think it actually would be better to make the fans share the same line with the heated bed, however. I would assume the motors are connected to the other 12V rail (it only makes senses to distribute the load like that), so in a way by connecting the fans to heated bed's 12V line, I am not impacting the motor's voltage/current/movement... ?
But then again, these two 12V lines are coming out of the same PSU, so at some point load on one of the rails could/would still impact the electronics/devices on the other rail... You know, like when a light bulb dims slightly when a fridge comes on...
