Part Cooling Fan Setup
-
I am trying to setup up a fan for part cooling during printing after the first layer is complete. I am using a 5v blower fan in the fan 0 port. Ive plugged it into the 5v always on port to make sure it works.
When i go to test the fan on the dashboard and turn it on nothing happens did i set it up correctly?
here is my config:
; Heaters M140 H-1 ; disable heated bed (overrides default heater mapping) M308 S0 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin e0temp M950 H0 C"e0heat" T0 ; create nozzle heater output on e0heat and map it to sensor 0 M307 H0 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H0 S260 ; set temperature limit for heater 0 to 260C ; Fans M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off ; Tools M563 P0 D0 H0 F0 S"Main" ; define tool 1 G10 P0 X0 Y0 Z0 ; set tool 1 axis offsets G10 P0 R0 S0 ; set initial tool 1 active and standby temperatures to 0C ; Custom settings are not defined ; Miscellaneous M501 ; load saved parameters from non-volatile memory M911 S10 R11 P"M913 X0 Y0 G91 M83 G1 Z3 E-5 F1000" ; set voltage thresholds and actions to run on power loss -
Which Duet board?
Can you send M122 and M98 P"config.g" in the gcode console and copy and paste the results here? That will give some additional information.
If it's a 5v fan, how are you providing power to the fan ports? By default they would match VIN.

Does the fan work if you send
M106 P0 S1? -

I meant that i tried moving the fan slider bar on the dashboard and nothing happens
Does the fan work if you send
M106 P0 S1?No nothing happens, when i plug the fan into always on 5v it turns on though.

picture of jumpers and fan connector on board....

If it won't come on with a manual command then either the wiring is incorrect, or the fan mosfet for that header is damaged.
Do you have a different fan to test on that header?
-
@Phaedrux the fans came in a set of 4 so i tried another and had the same result. Should i try it on one of the duex 5 fan headers?
-
yes trying a different header would be a good next step.
-
@Phaedrux I tried connecting to the fan port 3 on the duex 5 board but i get this error when i run the m106 command
On my dashboard no fans appear:
