#MCU protocol error, 4028 fan going full blast, 4 pin doesn't work.

Yeah I'm getting a mess going on for some reason. I just upgraded a fan and put a beacon on and now I'm getting errors all over the place.

I commented the pin for the fan to !PD15 cuz apparently J55 doesn't work.

Then the 4-pin fans part cooling is declared "not a valid pin name" after I just commented the line.

Uncommenting the line gives the first error but there's no updates available in the update manager.

Config included, I have no idea what's going on. I really need to get it fixed.

also line 159 - [include RatOS/4pin-fans/part-cooling-fan-25khz.cfg] is wrong, there are no 4-pin ports on the octopus 1.1

oh gotcha. Thank you.

#

PD15 did help the setup but it also caused the "recompile the firmware" to show up so i guess that's the underlying issue

Sorry I'm just really frustrated with this thing. The only major parts I added were the beacon and the 4028 but apparently that was just too much for a simple part swap and some klipper editing. A friend wanted to buy it and I keep getting delayed cuz of one thing after another.

micro SD card in the octopus with the firmware in it, wait a bit, take microSD card out.

fading vine
#

and that was the firmware from ratos, or somewhere else?

snow mauve
#

From RatOS, yes.

fading vine
#

paste the error you are getting

snow mauve
fading vine
#

so me the status of your machine that lists all the versions and if there are any updates

#

it should be under the machine tab if I remember correctly

snow mauve
#

I ran every update available.

fading vine
#

but it is saying your klipper is dirty, did you modify any files?

snow mauve
#

Nope.

fading vine
#

what do those info icons say next to klipper and moonraker?

Repo has untracked source files: ['klippy/extras/beacon.py', 'klippy/extras/gcode_shell_command.py', 'klippy/extras/linear_movement_vibrations.py', 'klippy/extras/ratos_homing.py']

Repo has untracked source files: ['moonraker/components/timelapse.py']

#

and fan is still going full blast atm

fading vine
#

did you manually install beacon?

snow mauve
fading vine
#

anytime the MCU goes into this state it turns the PWM signal off. These fans are set to go to 100 when it doesn't receive a PWM signal

snow mauve
#

right.

#

good to know

fading vine
#

Do you have another SD card for your PI? You could try moving to 2.1 which has much better support for beacon

#

if that fails, you still have this SD card

snow mauve
#

Yeah I just bought one to re-flash the firmware and OS.

#

So the new versions don't need to have the firmware flashed directly on the octopus anymore? All done from the pi?

fading vine
#

But ratos knows how to automatically flash it via the USB cable

snow mauve
#

yeah that's what I meant. Cuz before you had to flash it directly via a microSD on the octopus before installing ratOS on the pi.

fading vine
#

that is only the first time - that is with any board, you first have to flash klipper on it instead of whatever came with the board

snow mauve
#

Ahhhh

fading vine
#

the error you are getting are saying the firmware you flashed and the version of klipper you are currently running don't match

snow mauve
#

Okay. Reinstalled the OS with a new microSD and re-flashed the firmware, it said it was good.

Still got this error.

snow mauve
#

well, multiple updates got rid of that issue. NOw back to the classic MCU Unable to connect.

#

which happened after a klipper update
