Duet WiFi fan confusion
-
Hi all,
I'm trying to get a fan working to go into the housing for the Wifi board. but I only need it running at half speed if that (its a pretty beefy fan for its job)
It's a 4 wire 12v fan.
I've connected just the Vin and ground to the FAN1 connector on the board.
I can only make it turn on with this command "M106 P1 I1" The I1 part is needed or it doesn't work. And S0.1-1 or S50/S100/S255 have no affect on speed.
How do I slow down this fan?
All help appreciated!
Many Thanks

Connect the red and black wires to an always on fan connector, and the PWM wire to the FAN- pin of your chosen fan connector. Use parameter I1 innthe M106 command to invert the polarity.

I'll try that and report back, cheers!

Isn't P1 defined to be a thermostatically controlled by default? You need to disable it first:
M106 P1 H-1
Then send your variable rate.
