fans not responding.
fan 0 is hotend, fan 1 is part cooling
@ohluckyirish right, so you could swap the fan at the connector to have fan 0 as the part cooling fan.
Then you'd need
Fans M106 P0 S0 I0 F500 H-1 ; Set fan 0 value, gcode control for part cooling fan M106 P1 S0.5 I0 F500 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
I still dont get any movement out of the fans.
Does the fan slider in the DWC turn on the part cooling fan?
im new to the duet board ? please explain
Sure. DWC stands for duet web control. It's the web interface to control the duet.
no the slider doesnt turn the fan on.
So just to confirm you've switched the fan connections on the board and have made the configuration change I posted?
You could test the fan by connecting it to the always on fan header.
Also double check that you have the fan wires connected to the right pins. Positive and negative.
yes and neither fan is turning on when i have them in the always on connector
How are you powering the Duet right now, USB, or DC power supply?
If PSU, what voltage, 12v or 24v?
What voltage are the fans?
Can you test the fans by powering them directly from a DC PSU?
Do you have a known working fan to test with?

What voltage are you getting at always on sockets?
If you have a Duet 2 there is a fan fuse, is it blown?
all my fans were working fine before i upgraded to the duet board.

Check your fan fuse.
Check voltage at the fan fuse to see if you have PSU voltage. (one lead on the fuse top, one to ground on the PSU)
Double check your polarity.
Which Duet are you using? What revision?
What firmware version?
Can you send M122 in the gcode console and post the response here?

here is what i put as my fans
M106 P0 S0 I0 F500 H-1 ; Set fan 0 value, gcode control for part cooling fan
M106 P1 S0.5 I0 F500 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
which position should the jumper be in ?
@ohluckyirish it looks like you have a 12v power supply so if your fans are also 12v you would bridge the vin and vfan pins with the jumper to feed the fans 12 volts.
so the two pins on the right ?
it is currently on the Jumper: int 5V EN
@ohluckyirish that's right
the part cooling fan came on that is plugged into the always fan port, but none of the green lights come on ?
is there only post to be one jumper in ?
i moved the jumper from the int 5v en to the v fan jumper fan select. now only the fan comes on and none of the green lights on the board come on
