I have and EBB42 but I connected my 4pin OWM fan to the board and not the toolboard. I did not enable in printer.cfg FANS section any fan., but had made my entries in override. Now I see the fans as in image put the slider for the fan does not control the part fan. if i use M106 P2 S255 from console the slider will move to the 100 & on the monitor but the part fan still does not move. If I do a print the fan wil turn on but at 100% and always on. What is wrong I have in connected as in the image for the manta m8p install is it because I also have the EBB42?

Attach your printer.cfg, and maybe a crude wiring diagram?

#

P:S.I tried enabling a fan in the fans section and leaving mine in override I get the message. "pin PC14 is an alias for 4p_fan_part_cooling_tach_pin" which makes me think that my config for the fan is correct seeing they both want to use thatpin.

#

second

#

i'll send the image

#

like this as rat rig says, but could it be becuse i also have the EBB42 ?.

#

IT turns on during a print always on 100% but not control from the slider even if i'm not printing. It should turn on-

#

you need to uncomment line 157 or 158

#

lines 299-309, why did you add these? controller fans are fans that come on to cool the motor drivers

rigid ice
#

let me look

#

ok I enable line 158 and commented frm 299 to 309. But the fan does not move when i move the slider.

analog jackal
#

try 157 then

rigid ice
#

ok

#

the fan i bought from rat rig

#

same thing

analog jackal
#

you set the voltage to 12v?

rigid ice
#

yes

analog jackal
#

take a picture of your wiring please

rigid ice
#

ok one moment

proud dove
#

shouldn't it just be [fan] instead of [controller_fan]?

rigid ice
#

?

proud dove
#

For the part cooling fan in the override section

rigid ice
#

No took that out.

analog jackal
#

he shouldn't have to specify anything in the overrides. He is using a manta board which supports 4 pin fans

rigid ice
#

correct or so i believe

proud dove
#

I think the toolboard configs override the fan pins with ones for the toolhead

#

4p_fan_part_cooling_pin

rigid ice
#

I have nothing in overrides regarding fans now. and am using the only one in fans section.

proud dove
#

maybe try testing with just

[fan]
pin: 4p_fan_part_cooling_pin
#

as an override

analog jackal
rigid ice
#

[controller_fan part_fan]
pin: 4p_fan_part_cooling_pin
tachometer_pin: ^PC14
tachometer_poll_interval: 0.0005
cycle_time: 0.01

#

like this^

proud dove
#

No, just literally what I posted

rigid ice
#

ok

[include RatOS/4pin-fans/part-cooling-fan-100hz.cfg]
[fan]
pin: 4p_fan_part_cooling_pin but it still does not turn and RPM i red and zero

#

But why when i do a print it turns on?

analog jackal
#

upload your new printer.cfg

rigid ice
#

second

analog jackal
#

not part of your problem, but lines 158-161 aren't doing anything

proud dove
#

The lines that I put or the include that blacksmithforlife mentioned should be put in the USER OVERRIDES area

rigid ice
#

ok

analog jackal
#

and you are restarting klipper after each of these changes, correct?

proud dove
#

Keep the original include for the fan (the [include RatOS/4pin-fans/part-cooling-fan-100hz.cfg]) in the fan section

#

And then add one of the following to the USER OVERRIDES

[fan]
pin: 4p_fan_part_cooling_pin

[include RatOS/4pin-fans/part-cooling-fan-100hz.cfg]
rigid ice
#

ok the fan is on but turning very slow

#

I did that

#

added in overides
[fan]
pin: 4p_fan_part_cooling_pin and enable line 158

analog jackal
#

if that is too slow it might be the polling rate. You could try line 157 instead of 158

rigid ice
#

ok one moment

#

no same

#

and its on even if i set to 0

analog jackal
#

you would have to switch to using an enable pin instead

rigid ice
#

I have to comment out line 157 beacuse it says PA9 used multply times

#

that would be PB8 and not 9 9 is the controller fan

#

tried this with line 157 and 158 commented out. I see the RPM like 58 and fan is turning [controller_fan part_fan]
pin:4p_fan_part_cooling_pin
tachometer_pin: ^PC14
tachometer_poll_interval: 0.0005
cycle_time: 0.01

#

same as with line 157 enabled and [fan]
pin:4p_fan_part_cooling_pin

#

I'll check wiring again.

#

Well guess that i can't have apart cooling fan. need

#

wiring good

rigid ice
#

[controller_fan part_fan]
pin:!4p_fan_part_cooling_pin
tachometer_pin: PC14
tachometer_poll_interval: 0.0005
cycle_time: 0.01 with this its 100 on

#

well you see the RPM max and fan is turning slider has no effect

proud dove
#

The [controller_fan] sections don't refer to the print cooling fan

#

The print cooling fan has to be [fan]

rigid ice
#

ok

proud dove
#

Controller_fans are like ones that cool stepper motor controllers or if you want another fan to run when a certain heater is on

rigid ice
#

well its now half working, being i can control the on and off via slider but the RPM seem strange

analog jackal
rigid ice
#

ok

#

what value?

#

it s 0.0005

#

does not matter if 50% 100% any where the RPM will go feom 100 to 6000

#

call it a night for now, thanks for all your help to the both of you.
