fans not responding.

when i heat up my extruder past 45C the cooling fan does not turn on.
; Fans
M106 P0 S0.3 I0 F500 H1 T40 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P1 S0.5 I0 F500 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P2 S0.5 I0 F500 H1 T45 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned onplease help. (Think my Config.g is wrong )
-
You've got H1 on all of the fans. So that means they would all be tied to heater 1.
https://duet3d.dozuki.com/Wiki/GCode#Section_M106_Fan_On
and
https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fansFan 0 is typically the part cooling fan, so you would want that to use H-1 to disabled thermostatic control.
Fan 1 is recommended for the hotend fan because it will turn on automatically at power up incase the hotend is hot during a power cycle. In that case H1 might be correct if your hotend heater is defined as heater 1. Heater 0 is typically the bed heater.
Fan 2 can be used as a case fan or whatever you want.
So which fans do you have plugged in where?
Can you post the rest of your config.g so we can see which heaters are defined where?

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? -
@ohluckyirish
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
; Fans
M106 P0 S0 I0 F500 H-1 ; Set fan 0 value, gcode control for part cooling fan

which position should the jumper be in ?
