Yes. Add it below the other 2.

Done and it worked So now I will make the print again tommorow

Just one thing more how and where do I write M929 P"eventlog.txt" S1 ; start logging to file eventlog.txt
M929 S0 ; stop logging

You could add the start to config.g and the stop to your slicer end gcode.

Though I question if at this point you actually need it. Logging can also have a negative impact on performance due to the overhead. Best not to use it unless you need it.

I dont want to have the M929 running expect if it fails again with the hotend stops heating.

So it is just to see what happens if I get more fails.

Okay update

Maybe I have done some wires wrong... Both fans show up in web control and fan0 start on 3 layer like I told it to do i slicer but the other part cooler fan1 dont turn on unless I use the slider in control panel.

Another problem is when fans turn on hot temp fall from 240 to about 230-232 with only the fan0 if I turn fan1 on same time I will get Heater 1 fail. Can it be something about the power to the hotend ?

When fan0 turn on and I wait 1-2 min. and turn fan1 on slowly temp drops but no fail on hotend and after that temp is constand.

Ah yes there is one more piece to the config missing. We need to add the extra fan to the tool definition.

M563 P0 D0 H1 ; Define tool 0

Should become

M563 P0:2 D0 H1 ; Define tool 0

That should attach fan0 and fan2 to tool 0

To solve the fans cooling the hotend too much you'll have to aim the fans more carefully so they aren't blowing on the heater block.

You can also use a silicone heater block sock to cover it and shield it from the cool air.

And you can also run the PID tuning with the fans running at your regular print speed so that the model can account for the extra cooling of the block.

I have made a order now on silicone socks

Okay what is PID tunning and how is this done ?

I think I made a mistake with the tool definition I provided above.

M563 P0:2 D0 H1 ; Define tool 0 is incorrect.

I should have said M563 P0 D0 H1 F0:2 ; Define tool 0

hehe okay I was just about to write that it did not work, I wil try that setting when then print is done
