Duet 2 WiFi - connecting 3 wire 5v fans [solved]
-
Hi, what is the recommendation for using 3 wire fans with the Duet 2 WiFi board?
I have a Sunon Maglev MF40100v2-1000C-G99 fan that takes DC5volts and 0.65wats. It has 3 wires.

The 3rd wire is tachometer or PWM signal?
You'd likely be able to just use it as a regular 2 wire fan by connecting 5v and ground as normal.

the 3rd one is rpm.
if you want you can connect this up as well.
see
https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fansTacho wire (whatever wire is left, usually green or yellow): optionally, connect it to the cathode of a small signal diode (1N4148 should be OK) and connect the anode of the diode to pin PB6 on the expansion connector if the Duet WiFi/Ethernet, to provide a reading of the fan RPM. Or you can leave it not connected.

Thanks Veti, I wasn't sure if these instructions were for 4 wire fans only and I missed that last sentence completely.
