Since some hours try to figgure out what the faliure is i made
I'm using Cura and RFF3

Here my Config...may someone can help me because I'm out of ideas.

Thanks a lot

@topenga post your M563 line from your config

jumpedwithbothfeet

@topenga Best include your entire config.g, what do you have listed under M563? have you checked your wiring?

Thanks for that fast replay......hmmmm M563 is i guess the key?!?

jay_s_uk

@topenga and can you confirm that fans 0 and 1 are part cooling fans and fan 2 is your heatsink fan?

Topenga

@jay_s_uk
Auch ..... No..... part cooling FAN0, Hotend FAN1: and electronic FAN2

jay_s_uk

@topenga then you have both your fans and M563 setup incorrectly.
You should have

M308 S2 Y"mcu-temp" A"MCU" ; configure sensor 2 as on-chip MCU temperature sensor

That monitors the MCU-Temp for the electronics fan. You could use something else for the electronics fan but thats a good shout.

M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 C"PartCooling" S0 H-1 ; set fan 0 name and value. Thermostatic control is turned on
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 C"HotendSink" S0.95 H1 T45 ; set fan 1 name and value. Thermostatic control is turned off
M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency
M106 P2 C"Elect" S0.85 H2 T30 ; set fan 2 name and value. Thermostatic control is turned on

That sets fan1 to come on when the heater comes on and fan2 to come on if the MCU temp is above 30 degrees (you may need to increase that value)
And then change

M563 P0 S"0.4er Nozzle" D0 H1 F0 ; define tool 0

i.e. remove the :1 from F0 as you only map non thermostatically controlled fans to a tool

Thanks a lot... Will fix this afternoon and have feedback

Hello jay_s_uk said,

thanks a lot....it works....I wonder how long it will take until I'm relly fit due to configuration knowledge!

Great Forum dute to very kind and supportive member!
