How install fan1 and fan2 ?

[darkjorik]

How i understand, there is big difference in which position install fans.
When both fans work together they can form special eddy airflow
Who know right positions ?
Right, left, center.

I work with a Darko Juric, now I wonder if he's from the Ukraine...


Anyway though. There are a couple different kinds of fans on these machines.

There is 1 that cools the PEEK plastic barrel on the hot-end, commonly referred to as the "PEEK fan". It is the one that should be on all of the time, and I believe connects to the Heat 1 connector on the Rambo (check the manual to be sure).
Then you have what are called "layer fans" that blow air down on the plastic that you're printing. You can have several of these, or none at all. It will vary by part. This connects to the "normal" fan connector on the board.
You may also have a fan to cool your Rambo board that can connect however you like. I connect this fan directly to the 12v power input connector, but you could wire it to Heat 1 also.


So does that answer your question? Always run your PEEK fan, and choose the best layer fan setup (quantity and aiming) for yourself. Run a Rambo fan if you've got one, wiring can vary.
