I want to install a separate fan on the creatr to control the cooling of my parts.
In the first step I want to test it with the present fan, but you can not adjust it on the Repetier Software.
The Gcode M106 (fan on) don't work at this fan.
So my question is at which pins I have to connect a new fan to control it?
The fans on the extruders are connected directly to the power supply and can't be controlled. I've attached the info that matches my printer that shows the connection points for a nozzle cooling fan.

thanks for your fast replay.
You have the Leapfrog electronic board and I have the older arduino mega 2560.
At one website they write something about a connection at D9 to control a fan or something. http://jtechphotonics.com/?page_id=1503
I found this after I search after the gcode M106 to adjust the rpm of the fan.
Unfortunately it don't work. There is no power at this connection.
If you have any idea please let me know.
