Are you using ratos?

Yes

Are the fans currently working? I'm not sure what your question/problem actually is, asking clarifying questions. Not clear if you're trying to fix something, or change something

Red rig says that the red and black wire has to be plugged into an all the time power and I have a white wire that is supposed to be the switch wire to turn off and on. I guess I wanna be able to control the fan to turn it off or different speeds depending on the filament like ABS says zero fan Rat rig not red rig sorry The fans are stuck at 100% all the time

What fans are you using? Did you get them from ratrig?

Yes, I bought the fully upgraded kit from rat rig 4028 Axial - Sanyo Denki 9GAX0412P3S001 (12V 1.3A 25000RPM) I think it’s the fan that came in the kit

If wired as instructed they should not be at 100% once the pi has completed booting. Double check that the PWM wire is connected, and to the correct pin.

OK, I’ll put it all back like I had it hooked up to the tool head and motherboard. I’ll send you videos and pictures to show you what my problem is and how the printer config is set up. I’m doing my best to try to explain everything I possibly can.

Now what part of the printer config do you need to see what my settings are is it the one in the ratios.cfg because the one in the printer.cfg has nothing involving fans in it

So that white wire is the pwm from the fan, yeah? and power/gnd is coming from the octopus. Thats correct, and you haven't edited any files right?
TheTik

Hm. Double check this step that the blue wire from the fan is going to the white wire of the connector: https://ratrig.dozuki.com/Guide/12.+Electronics/250?lang=en#s2634

This guide is still in progress, as more detailed instructions on how to prepare all wires will be added in the next few days.

yes sir everything is how it was and that is right about the wires yes the link you added is how i did it
TheTik

So the fan is correctly getting power, but it sounds like the pwm isn't working. When these server fans aren't getting proper signal, they run at 100% for safety's sake.

On your dashboard do you have something like this, but with two fans listed?

okay, thats good at least. What colors are coming directly out of the fan? the pictures I'm seeing suggest they should be red, black, blue or brown, and a possible white
charles
charlesOP3mo ago
red/black form fans to motherboard white to the ebb and thoes are the wire colors 1 sec i ans so sarry i an so rong black wire from fan to black on motherborad red wire from fan to red on motherboard tan/ brown to white wire to ebb and there is a yellow wire to nothing
TheTik
TheTik3mo ago
Okay, that sounds right then. I would triple check that the connection is good, that the crimps are good, that wires aren't loose also
charles
charlesOP3mo ago
ok so the white wire does go to the tanish wire
TheTik
TheTik3mo ago
Is anything else hooked up to the toolboard working?
charles
charlesOP3mo ago
not sure i just turned it on and the fans are so loud i had to turn it off but i can check just was doing it step by step and i did not know if i did it rong
TheTik
TheTik3mo ago
If the wire is hooked up correclty, the fans will turn off once the pi finishes booting and sends the run speed signal to the toolboard
charles
charlesOP3mo ago
ok but it was for the time i could look into the congig files and no change
TheTik
TheTik3mo ago
right, which strongly suggests the cabling doesn't have connectivity
charles
charlesOP3mo ago
the hot ends i put to 100c and got hot and the hotend fans came onfans came on
TheTik
TheTik3mo ago
okay, thats good. Means toolboard is responding oh!
charles
charlesOP3mo ago
yep
TheTik
TheTik3mo ago
On that part fan slider, if you move them to 100% do the fans turn off?
charles
charlesOP3mo ago
and then they shut off when they cooled down 1 sec ill see if i move the parts fans to 100% see if they shut off ok yes if i turn it to 100% they shut off
TheTik
TheTik3mo ago
aHA!!
charles
charlesOP3mo ago
lol so what now
TheTik
TheTik3mo ago
we need to invert the pin
charles
charlesOP3mo ago
ok
TheTik
TheTik3mo ago
trying to find the right text, can you drop your printer.cfg in here? we'll need something like
[fan part_cooling1]
pin: !toolboardt0:PA0
[fan part_cooling1]
pin: !toolboardt0:PA0
but most of that is wrong, need to find the right names
charles
charlesOP3mo ago
sorry
TheTik
TheTik3mo ago
delete that, drop the file in here. Thats impossible to read lol oh! actually that does still have what we need If you're going to post text like that, use a triple backtick (key left of 1 to make a block of text
charles
charlesOP3mo ago
will not let me
TheTik
TheTik3mo ago
see where it says
pin: toolboard_t0:PA0
pin: toolboard_t0:PA0
? put a ! in front of toolboard so that line becomes
pin: !toolboard_t0:PA0
pin: !toolboard_t0:PA0
then do the same for the other fan

lots of people do, I'd ask what the error message is but I'm trying to fix your printer not diagnose discord XD
charles
charlesOP3mo ago
cool that worked
TheTik
TheTik3mo ago
hooray!
charles
charlesOP3mo ago
i was told not to change the RatOS.config
TheTik
TheTik3mo ago
correct, you shouldn't. Was that not from your printer.cfg?
charles
charlesOP3mo ago
i have nothing to do with fans in my printer.cfg
TheTik
TheTik3mo ago
no problem, we'll use printer.cfg to override With the message deleted I don't see the section header names, we need that to add to printer.cfg so put ratos.cfg back, but put the section AND pin lines in your printer.cfg
charles
charlesOP3mo ago
this is my printer cfg
charles
charlesOP3mo ago
this is my ratos cfg
charles
charlesOP3mo ago
thats all i know how to show you
TheTik
TheTik3mo ago
so you just need to put
[fan_generic part_fan_t0]
pin: !toolboard_t0:PA0
[fan_generic part_fan_t1]
pin: !toolboard_t1:PA0
[fan_generic part_fan_t0]
pin: !toolboard_t0:PA0
[fan_generic part_fan_t1]
pin: !toolboard_t1:PA0
in printer.cfg
charles
charlesOP3mo ago
any where in printer.cfg
TheTik
TheTik3mo ago
put it like, line 45
charles
charlesOP3mo ago
ok i changed the ratos.cfg back and added it to my printer.cfg and it works sorry this is all new to me and i dont want to fug a $4000 printer if i ever have more questions can i hit you back up?
TheTik
TheTik3mo ago
Sure, I'll probably suggest you open a new thread 🙂 At least now you can hear yourself think while you continue working on it lol
