Fan control temp. problem

M950 F0 C"fan0" Q500                               ; create fan 0 on pin fan0 and set its frequency

M106 P2 S1 H2                                      ; set fan 2 value. Thermostatic control is turned on

Even though there is no "T" set temperature M106 P1 or P2 turns with "M106 P1
Fan 1, speed: 0%, min: 10%, max: 100%, blip: 0.10, temperature: 45.0:45.0C, sensors: 1, current speed: 0%:"

I didnt set the temperature: 45.0:45.0C how does this comes out with that settings? Now I cant control the fans if the temp is below 45c

If you want to control the fans use H-1 to disable thermostatic control.

If you want thermostatic control, define your own temperature range with a T parameter.

45c is the default used in the firmware likely due to that being used for the hotend fans by default.

Thanks. When I do this(H-1) I am loosing my fan control over DWC. It says no fans.

May last configration was like this and it was working very well.

These two fans are for part cooling. Extruder fans are always on.

BTW is there any Gcode for clearing Duet board cache? Sometimes I feel like my config.g is not updated.(config.override is cleared)

@secure said in Fan control temp. problem:

What version of DWC are you using?
Do you see a text label that says Fan Visibility?
What fan do you have defined in your tool definition (M563)?

Duet Web Control 2.1.3
There is no "Change visibilty" It says just no fans.

This config was working before I updates to DWC 2.1.3

Back to Duet Web Control 2.0.4 fixed. @chrishamm
