thanks for your quick response. upon further research the VSR pin takes 0-5V or PWM for the speed input of the fan. so i guess this will work with out9?!

RE: connecting a BLDC controller to duet2
HI all. so i have finished my first CoreXY printer with an duet3 6hc controller and id like to install a big centrifugal fan/blower as part cooling fan. Its a brushless 7040 fan (https://www.aliexpress.com/item/10000048326249.html?spm=a2g0o.cart.0.0.45413c00nJsmPg&mp=1) which needs to be connect with an extra driver.
So I have 2 questions
(I started with an Ender 3 V2 a year ago and well I have constantly been learning )
Do i need any extra precautions connecting the driver and blower to the duet3 board? (its rated max. 3A /peak 6A which should be covered by out_1-out_3 right? (Please screenshots for specs)
is the wiring correct? (Please screenshots for specs)
a) 24v from either OUT_1,OUT_2 or OUT_3
b) driver control from 5v PWM (out9)
driver --> Duet3 (5V PWM(out9))
+5V --> 5V_EXT
VSR --> out9
GND --> GND
What do i need to add to the config.g anything special or just like every other fan?
Your help is appreciated. Thanks
