What version of ratos? What errors are you getting? What screen are you on?
i have the newest realease candidate and this is the screen i am on
i have put the firmware on the sd card and it just wont detect
how did you verify the firmware got onto the board?
i dont know how to
i put it on the sd card on the control board
and then restarted it

Step 6 is how you would verify.
ok
the status led is not blinking
i have tried different usb c cables
but the kraken still wont just take the firmware
should i try unplugging the usb to the pi from the kraken?
Yeah, try unplugging everything from the kraken other than power
i still dont think its working
imma try a different sd card
thats 128mb
Hope thats big enough for the firmware file
the firmwair file is 30 kb
ah, good
the led on the board is still not flashing
its still not working
i sent an email to where i purchased the board from
Yeah, that is the best next step. If they won't/can't help you may try reflashing the bootloader:

show us a picture of your wiring
unplug everything that isn't the USB C to the pi and the power to the board
Will try in a bit
got it flashed and everything but i have this error now
is this because i dont have a hotend fan?
pretty sure you have to have a hotend fan
chube air on takeoff does not need a hotend fan
@blacksmithforlife 🇺🇸 do you have a solution for this?
debug.zip please
You need to put in the value for the fan in the config, even if you are not running one Something like this: [heater_fan toolhead_cooling_fan]
pin: toolboard_t0:PB1
max_power: 0.995
shutdown_speed: 0.0
heater_temp: 75
where would that be in ratos? b/c not everything is in the normal printer.cfg
i also need to set the part cooling to use both 4pin headers on the kraken
that is not the debug.zip - you can download from the sidebar in the configurator
is this the correct file?
yes
In the printer.cfg.
where in it its not like the normal klipper config its missing a load of stuff
I am not sure what you are asking, printer.cfg is a separate file.
i know
but ratos puts suff in different places
like there is no z drive ration in the printer . cfg
As mentioned in the commissioning guide, you do not change anything in ratos, all additions and modifications are to be made in printer.cfg.
ok
so what should i add to fix that error
about there not being a hot end fan
I already gave you the answer above, you need to put in a value even if you are not running one.
ok do you think that will solve the error?
Yes.
ok and then what shoiuld i add to make it for part cooling it uses both 4 pins on kraken?
I think you said you are running IDEX, I don't have any experience with dual toolheads
no idex
just the single tool head has 2 fans
@cgrr [VC 3.4 hybrid 500] still have the error
Post you printer.config and stay in one channel, not two.
