Hi,

I assume you verified that fans are connected to the correct connectors on the board?

Frederick

When I turn on the hotend fan in the duet web control it turns the right fan on. So I assume its ok.

The hotend fan should not be showing in the duet web control. Only the part cooling fan should be visible.

I know it has no control. I just turn on the hotend and when the temp. riches 45deg. it turns on.

@luka1952 I am confused now. You told @fcwilt "When I turn on the hotend fan in the duet web control it turns the right fan on. So I assume its ok."

luka1952

@generisi Sorry my mistake.

To be clear:
I have only one slider in duet web control and it is part cooling fan.
When I use it part cooling fan is working.
When I set temp. higher the 45 deg. on my hotend the hotend fan kicks in.

M563 P0 S"Sherpa/Dragon" D0 H1 F1 ; define tool 0

Is this correct?

M563 P0 S"Sherpa/Dragon" D0 H1 F1 ; define tool 0

I'm assuming you should have F0 instead ?

@gixxerfast
I've just change it.
Before it was F0 but I've got the same problem.

GeneRisi

@luka1952 Your config has this
M106 P1 C"Hotend Fan" S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
I think you either want to say S255 or S1.0 . S1 looks to the firmware like you want the fan set to 1 out of 255.

Gixxerfast

@luka1952 It should be the part cooling fan associated with the tool so it should be F0 (or nothing at all).

Also you should (as far as I know) end your config by selecting the tool with a:

T0

Also try removing the S"Sherpa/Dragon" (just to test)

And the above that GeneRisi wrote ^

luka1952

Ok, thanks I'll try to change it and see what happens

That's what the docs say. However testing reveals that, in firmware 3.3 at least, S1 get special treatment and is the same as S1.0

Did you look at the slicer code and verify the M106/M107 commands have no parameter?

Frederick

@fcwilt
Yes,it has no parameter.

Could you post your latest config.g and a picture from DWC where one can see the fans?

So just to recap, before you run the gcode from the slicer the hotend fan (Fan 1) is running and directly when you start the slicer gcode, fan 1 stops?

And, when you move the tool fan slider in DWC the part cooling fan starts and stops?

Hi everyone.
After making suggested changes everything is working correctly now. Thanks a lot
