Part cooling fan not strong enough

; Fans
M950 F0 C"fan0" Q50000 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned offYour fan frequency is very high. Set it to 500, not 50000
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp
This is not the correct thermistor setting for an E3D thermistor (assuming you fitted one of theirs when fitting their hotend)
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

@andreic I think your ducts produces to much back pressure. You should test the fan in "free air" for comparison...

Thanks for looking and answering. Yeah, I did a test with that frequency just to see what happens. it's 500 now and it was before too.
About the thermistor thou, I did not notice that. I followed some instructions on what to select and I did not check on the thermistor for E3D. You are right it is a full E3D kit and it has the E3D Thermistor.
Can you help me out with some info on what should be there instead? I didn't have problems with it but I'd rather have the correct settings.
Thanks again

Yep tried it. I have an identical one on another Kossel with stock board and it works great and I have been using it for a year.cheers

just tried it and it seems to be messing up my bed thermistor or something

@andreic post your whole config and the output of M115

@andreic you've changed the temperature sensor for your bed rather than the hotend.
That's why your bed isn't working correctly.M308 S0 p"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0 M307 H1 R1.892 C235.1 D6.18 S1.00 V12.5 ; enable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S120 ; set temperature limit for heater 0 to 120C M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.060000e-8 ; configure sensor 1 as thermistor on pin e0temp M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H1 S280 -
yeh...you're right. hurry makes stupid.
Works now. gonna do some tests with this tomorrow.Thanks and i'll get back with the results.

@andreic Perhaps somebody replaced the original fan with a quieter one but didn't check the CFM rating and it's too low.

@donstauffer
Nope. Tested it on the other system and there is a clear difference.@jay_s_uk
Still the same problem after a PID tune too.
