Failed SD Image

[thick seal]

Flash to image SD card fails every time no matter what SD card I use 16GB to 128GB all SanDisk SD Cards.

[brittle sparrow]

Are you using Balena Etcher? How does it fail? What device are you using to write the sd card? Is it a usb sd card reader? if so try another usb port.

[thick seal]

Hello @brittle sparrow

I'm using Balena Etcher.

It fails at the end of verification.

Using my desktop windows PC.

I have a USB SD card Adapter.

I've tried 2 different ports.

[brittle sparrow]

Download the image again, it might be corrupted.

[thick seal]

Okay will do.

Thanks

[thick seal]

Tried it but failed again

[brittle sparrow]

Works fine for me (and nobody else reported this issue), so i'm thinking it's your card reader

Are you doing something to the .xz file before flashing?

[thick seal]

Download from github then open Balena and select

@brittle sparrow if you're in the states I'll pay for an SD card with the flashed image on it.

[brittle sparrow]

Then i can't think of anything other than the card reader.

[brittle sparrow]

I'm in Denmark, Europe so it's gonna be some tough shipping

You can try and ignore the warning and use it anyway, but i'm guessing it's probably right when it says it didn't verify

(that's why Balena is recommended, to avoid odd issues down the line because of bad flashing)

[thick seal]

Ah and yeah

I'll grab another card reader

What's strange is all the files and folders on the card.

[brittle sparrow]

Yeah everything is written, but when it's read back it doesn't correspond to the contents of the image. Ie. something went wrong during flashing, that's why balena is complaining. You can try and use it, but it's prolly right that something is broken 😄

[thick seal]

Yeah I had tried in the past. Didn't get anything from the pi for a hot sport or even via Ethernet.

Also using a CM4

Trying a different computer with built in SD card reader

[thick seal]

@brittle sparrow flash complete and successful. Switch from my PC to Laptop with a built in SD card reader.

[thick seal]

@brittle sparrow

Is there anything special needed to flash the CM4101032 Raspberry Pi 4 Compute Module CM4 1GB RAM 32GB eMMC

[thick seal]

From what I saw it looks like this is the way to do it hopefully

[thick seal]

Success and thanks for all the help 😁

[brittle sparrow]

Yeah that doesn’t work with SD cards, you need to flash the eMMC itself

[brittle sparrow]

Oh nice 👍

[brittle sparrow]

@thick seal Continue here instead of DMs. I think the compile_firmware button is hidden on your screen size, click the cogs in the upper right corner and navigate to "Dashboard"

There you can configure whats visible on "Desktop"

Enable the "scripts" panel

Normally it's below the console

[thick seal]

@brittle sparrow okay

And will do I hit the V3 button and couldn't figure out how to get it back so in the middle of flashing the image again

Love the printer cfg setup though.

@brittle sparrow that did the trick 😁

[thick seal]

@brittle sparrow got the firmware flashed on the octopus pro F446 board but I'm having some issues even after going through the Printer CFG.

Getting a MCU unable to connect

[brittle sparrow]

This means that it didn't flash correctly / it's not booting because of a short, etc. Check: https://discord.com/channels/582187371529764864/1046952693480038500

[thick seal]

@brittle sparrow that's what I thought but I have everything disconnected

[brittle sparrow]

And you selected the right board in printer.cfg?

[thick seal]

Yes

[brittle sparrow]

Try flashing this one

[thick seal]

Okay I'll try it tonight have to drop the kids off.

That's the CFG

In short running the Pro F446, BLtouch, rapido, orbiter and it's a 400 V3 might be forgetting a few things

[brittle sparrow]

It looks correct

Which means the firmware didn't flash correctly

[thick seal]

Ah

Makes sense and what I figured. So reflash the firmware.bin file then

[brittle sparrow]

yep pretty much

[thick seal]

Thanks again for the help, the ratrig community was a big part of me deciding to go ratrig.

[brittle sparrow]

Glad to hear it! Let me know if you continue to have problems 🙂

[thick seal]

@brittle sparrow
Will do. I'm going to have to figure out how to change info for the cfg as I had to move things around for the motor drives. Mine don't correlate to the ratos diagram anymore and I noticed the cfg isn't like the one I have for my other printer setup on klipper.

[brittle sparrow]

You can override the driver and stepper pins in the bottom user overrides section

[thick seal]

Awesome and I thought so but didn't look into it that much yet. As I need to get the mcu issue fixed first.

[thick seal]

I'm thinking i have a bad Octopus Pro as MCU fails to connect and ive flashed firmware a few times with no change.

[thick seal]

Tested with known working Octopus pro 446 from my other printer and still MCU unable to connect.

could this be an issue with the Pi CM4?

Going to try Flashing the RatOS again on it

[thick seal]

Reflashed the CM4 and still no luck.

[grand nebula]

did you work through all the common issues listed in https://discord.com/channels/582187371529764864/1046952693480038500 ?

[thick seal]

yes

[thick seal]

I have 2 of the same Pro 446 boards both with just 24v hooked up and both have been flashed a few times via the sd card. the .bin changes to cursor as it should

[grand nebula]

run dmesg -w and while it is running, plug your octopus board into your PI
so what's the output of this?

[thick seal]

That is the only part that im at a lose with as i have a Cm4 and not sure how get the IP and know if SSH is activated

[grand nebula]

if you have mainsail interface accessible, it lists ip address on the machine tab

[thick seal]

One sec I'll look I didn't see it before

Ah I see it

Well I see two 😅

[grand nebula]

are you plugged into ethernet and connected to wifi?

since they are eth0 and wlan0

[thick seal]

yes for some reason doesnt work without the ethernet

what is the login info?

[grand nebula]

that doesn't make sense, but ok.
username: pi
password: raspberry

unless you changed it

[thick seal]

okay im in

run dmesg -w

[grand nebula]

then plug in your usb that connects to octopus

[thick seal]

okay let me retry i had it plugged beforhand

okay im going to plug it in what should i see

or what am i looking for

[grand nebula]

post the output

[thick seal]

okay plugged it in and i didnt see anything

[grand nebula]

ideally you see it trying to connect the usb

just double checking, you are connecting to usb A port on the pi to usb C port on octopus board?

[grand nebula]

what's that other usb that is plugged in?

[thick seal]

the USB C at the Pi is power

The USB A on the Pi is going to the USB C on the Octopus Pro

the other USB A not plugged into anything is just going to a USB outlet on the side of the machine

[grand nebula]

looks like the octopus cord is unplugged, and something else is plugged into usb A port

next to the ethernet cord

[thick seal]

So use the USB A port on the Octopus and not the USB C

The pi is USB C to power supply and USB A to Octopus USB C

[grand nebula]

purple line to octopus looks unplugged. what does red line go to?

[thick seal]

It's just looped behind the bar

Didn't want to put a tight bend on the cable

[grand nebula]

try plugging something else into the usb port on the pi while running dmesg -w

[thick seal]

Okay how about a flash drive?

[grand nebula]

if nothing still shows up in output something is up with your pi ports

[grand nebula]

idk, try it

[thick seal]

yup DOA

plugged in and nothing popped up

[grand nebula]

just to be sure I would try some other usb items, but it is looking that way

[thick seal]

it has power but nothing else

tried my phone with a couple of usb cables

looks like ill need to find an actual Pi and not this POS CM4

[grand nebula]

not sure if its the cm4 or the board its attached to

[thick seal]

yeah im not either but not sure if its worth spending another 30 on a board that might be faulty or just spend the money an a pi

it also bothers me that it shows the WIFI but Mainsail wont connect without the ethernet

[grand nebula]

I would contact whoever you bought it from and ask for refund

[thick seal]

yeah

ill see if they will exchange it and ill order an actual pi

Wondering if i could run the ratrig off the sonic pad temporarily lol

[grand nebula]

not officially, but I could send you my notes on how to do it based off my cb1 experience. but def advanced work and you would be on your own for support

[thick seal]

Yeah I've built a few off the pad but the CFG would be my question

All for me have been bed slingers on the pad.

Not sure how it would have to be for the bed leveling to work properly

[brittle sparrow]

Yes. You need to explicitly enable USB OTG via a jumper on the host board you're using.

[thick seal]

Ohh do you know what jumper it is?

https://www.waveshare.com/cm4-io-base-a.htm

This is the base board I have

[brittle sparrow]

I don't, but it might not be necessary on this one.

That jumper is mostly present on controller boards made for CM4's like the BTT Manta boards.

Oh wait @thick seal are you running 1.2.4?

1.2.4 doesn't support CM4, v2.0.0 does

[thick seal]

1.2.4?

Rato

Ratos?

[brittle sparrow]

You can fix it though, you need this in /boot/config.txt

[cm4]

Enable DWC2 for usb on CM4

dtoverlay=dwc2,dr_mode=host

[brittle sparrow]

yes

[thick seal]

I didn't see a different version

[brittle sparrow]

That's because 2.0.0 is in beta currently

[thick seal]

Ahh

Well I'm currently on my way to get a pi 4 8gb

I'll install the beta and try it out

Will 2.0 fix the wifi issue too?

[brittle sparrow]

what wifi issue?

[brittle sparrow]

You can just do this and save yourself some money: #1076758202881945680 message

Or go for 2.0

You don't have to buy a pi 4 😄

[thick seal]

I could only connect to it with the Ethernet

Too late 😅

[brittle sparrow]

haha fair enough

[thick seal]

I'll try and get the cm4 to work as well.

[brittle sparrow]

Don't know, i've only tested it on a CM4 without wifi, but i don't see why it wouldn't work.

[thick seal]

Yeah I'm not sure and for me rather not have to reinvent the wheel on this.

So I was looking through the cfg and saw the override area on the bottom.

I take it use that area to make the driver output changes.

If so do you have a link or photo of an example? I've never did changes as override.

[grand nebula]

You shouldn't need to do that with Rat-OS. Are you using some completely different hardware than what the ratrig kit comes with?

[thick seal]

I got my v3 used and it was a mess so I drew up and made a new panel for all the electronics.

[brittle sparrow]

Correct.

[brittle sparrow]

There's no difference to regular configuration

You just write your driver settings tehre

[thick seal]

How I got it

[brittle sparrow]

eg:

[tmc2209 stepper_x]
uart_pin: whatever

[stepper_x]
dir_pin: whatever
step_pin: whatever
enable_pin: whatever

Then just look up the pins you need in the pinout for your board

[brittle sparrow]

quite an improvement lol

[thick seal]

Awesome so it's just use the normal klipper call outs

[brittle sparrow]

basically because of wire lengths i assume he had to switch the bottom 3 with the top 3 steppers.

[thick seal]

Yes it was a wreck before

[brittle sparrow]

yep!

[thick seal]

That and better routing

[grand nebula]

ahhh

[thick seal]

okay so i think my router is blocking the pi

i can see the new pi4 if i use ethernet

[grand nebula]

what do you mean by that? You can't access ratos.local? Or even using IP address for the pi you can't access it?

[thick seal]

correct

I followed the Wifi setup and saved the pass code for the wifi

[grand nebula]

does your router list it as connected?

[thick seal]

Haven't gotten that far but i did notice it still shows the Ratos hotspot

[grand nebula]

then it isn't connected to the wifi

[thick seal]

I do have good news, the Pi can see the Octopus board now

I thought the same but when i went to redo the wifi it comes up bad gateway

[grand nebula]

Does your wifi SSID or password have spaces or special characters?

[thick seal]

no just numbers

[grand nebula]

did you connect to the hotspot first?

[thick seal]

yes

Its WPA2

[grand nebula]

so after connecting to ratos hotspot you navigate to 192.168.50.1?

[thick seal]

yes

i tried this as well http://RatOS.local/

[brittle sparrow]

That means connection to nginx on the pi is working but the configurator is dead

Can you ssh into your pi and download ~/printer_data/logs/ratos-configurator.log and post it here?

[thick seal]

yes

pi@ratos:~ $ /printer_data/logs/ratos-configurator.log
-bash: /printer_data/logs/ratos-configurator.log: No such file or directory
pi@ratos:~ $ ~/printer_data/log/ratos-configurator.log
-bash: /home/pi/printer_data/log/ratos-configurator.log: No such file or directory
pi@ratos:~ $

[thick seal]

also should I do the updates?

[thick seal]

Okay I got WiFi working

I reimagined the SD card and started over. Now wifi works and I can see the board

I'm still seeing the about photo with everything saying invalid

[brittle sparrow]

It's /home/pi/printer_data/logs/ratos-configurator.log

[brittle sparrow]

Okay this is good.

[brittle sparrow]

That's just because it hasn't been able to query github for the information yet

Hit the refresh button in the title of that panel, that should fix it. If it doesn't you have network issues.

[thick seal]

Okay check it out in a bit

[thick seal]

@brittle sparrow I thought the wifi was working but my PC just auto reconnected to the ratos hotspot 🙄

pi@ratos:~ $ /home/pi/printer_data/logs/ratos-configurator.log
-bash: /home/pi/printer_data/logs/ratos-configurator.log: No such file or directory
pi@ratos:~ $ /home/pi/printer_data/logs/ratos-configurator.log
-bash: /home/pi/printer_data/logs/ratos-configurator.log: No such file or directory
pi@ratos:~ $

[thick seal]

i was able to run the updates using the ethernet

everything but wifi seems to work

[brittle sparrow]

Hmm.. How did you flash the sd card? Did you use the Raspberry Pi imager? Because that might break the wpa_supplicant functionality.

[thick seal]

I used balena

Followed the guide online

[brittle sparrow]

That's really strange

Can you try manually editing /boot/ratos-wpa-supplicant.txt ?

If that still doesn't work, i'm gonna have to blame your router. I'm having no trouble connecting to wifi on Pi4, 3 or zero two with the latest beta.

[thick seal]

will try now

pi@ratos:~ $ /boot/ratos-wpa-supplicant.txt
/boot/ratos-wpa-supplicant.txt: line 54: syntax error near unexpected token }' /boot/ratos-wpa-supplicant.txt: line 54: }'
pi@ratos:~ $

[brittle sparrow]

You need to edit it, so run:

nano /boot/ratos-wpa-supplicant.txt

then change the

network={
...
}

section to match your wifi settings.

[thick seal]

okay

ah ha

that did it

not sure why it didn't work the normal way but now it works

I'm currently going through making the needed changed in my CFG in the overrides. Once I'm done mind just giving it a glance as i need to make changes to more then just the drivers as i want to add all the fans to the board plus run both parts cooling fans on there own pin. Also I'm planning to swap to the APUS extruder at home point so i will need to be able to edit the current and rotation distance.

[brittle sparrow]

I have a theory. Needs changes to the configurator, will see if i can get to it tomorrow.

[brittle sparrow]

sure

[thick seal]

awesome as I'm getting errors with the overrides

getting a parse option 'fan_speed' error also run_current error

[grand nebula]

Line 342 - that needs to go under a header, but currently is just "floating" there under controller fan header which is wrong

And for the controller fan definitions you have 1,2,3 just dangling off the name. Either connect it with something or just leave it off.
i.e. controller_fan_1 or just leave as controller_fan

The fan speed error might be because you started with a dot (i.e. .75) but you need a leading zero, i.e. 0.75

Not sure why it is complaining about the run current

Maybe it needs a space after the :?
You have run_current:0.707 but you need run_current: 0.707

[thick seal]

Thanks Ill make the changes.

i # out the extruder run current as i plan to use that for when i switch to the APUS

Okay i updated everything and now i get pin fan_controller_board_pin is an alias for PD12

I think its because am trying to run both parts cooling fans in parallel but off there own pins

pin fan_toolhead_cooling_pin is an alias for PE5

[grand nebula]

Line 309, you are trying to use pd12 for a fan, but ratos is already defining that pin for a controller fan. You can have the same pin for fan and controller fan. So redefine the fan_controller_board_pin to something you aren't using, and then you should be fine. needs to be done before you use pd12

You might be better off copying the board import (line 22 shows where it lives) to the same folder your printer.cfg is, then change the pin definitions there, then importing that instead of line 22.

That way you don't have to keep fighting the already defined pin names

But up to you

[thick seal]

So change the config.cfg for the board

Have you ever used

[multi_pin my_fan]
pins: PC7, PC6

[fan]
pin: multi_pin:my_fan

[grand nebula]

Yes https://github.com/jscancella/myKlipperFiles/blob/main/vcore3-printer.cfg#L24

[thick seal]

ahh okay i was trying to get that to work for my parts cooling fans

is it possible to do that in the board cfg?

Also how do i make the config file not read only? i tried downloading and editing it but i can't upload it from there

[grand nebula]

Those files are just for logical separation. You could copy them all to printer.cfg and it would still work.

Just follow the correct convention, don't directly edit those ratos files. If you need to override them, create new files copy the ratos one, and then override the new one however you want

[grand nebula]

You don't, they are read only for a reason

[thick seal]

okay

[grand nebula]

Just copy it to a new file like I outlined earlier

[thick seal]

Okay

[grand nebula]

Yeah, now just redefine the pins to the aliases so they are correct. Then ratos should just work

[grand nebula]

You have one too many config in the path

[thick seal]

🤦‍♂️

[grand nebula]

[include config466dualPF.cfg]

[thick seal]

Ah hA

[grand nebula]

Sorry, I should have spotted that earlier

[thick seal]

that worked

no worries this is new to me I'm used to having everything laid out the old way and filling it all in

how would i call out the multi fan in the board CFG for the dual parts cooling fan setup?

[grand nebula]

Same as before I would imagine

And then just override it in the USER OVERRIDES section like I did in my config

[thick seal]

okay

[multi_pin my_fan]
pins: PE5, PD12

[fan]
pin: multi_pin:my_fan

Unknown pin chip name 'multi_pin'

Never mind

all fixed

deleted this and it worked
[fan]
pin: multi_pin:my_fan

Thanks again for all the help and hopefully this helps someone else along the way.

[grand nebula]

Good luck

[thick seal]

Thanks again for all the help I couldn't have done it without the amazing RatRig community

[thick seal]

Any chance you might know why the X would show trigger on the limit switch even if its not hooked up and no matter what pin you put it on? Could it be a driver issue?

[thick seal]

I've nailed it down to something in the CFG. List Below is what I've tested and found.

Moving limit switch pin in Config = no change
Unplugged limit switch = no change
Swapped drivers around = no change
Moved X Driver from 5 to 4 & re did the pin call outs = no change
swapped the X & Y in the config = Moved the issue from X to Y

Not Sure what it could be causing the issue.

[thick seal]

This is the config file for my Octopus pro 446

This is my cfg

[brittle sparrow]

Check that you don't have the DIAG jumpers inserted

[thick seal]

I take it this is what you are talking about.

I'm wondering if I need to add ^ for that one for some reason

[brittle sparrow]

So it's not that at least.

[brittle sparrow]

Oh your endstops are miswired

You're shorting your pins

White and red should be swapped.

Hopefully you didn't fry your mcu.. yet

(this is why there are warnings about this everywhere in the docs)

[thick seal]

That's super strange as thats how it was when i got it and thats the only one that works the one with the white connector dosnt work

I think I know what happened

[brittle sparrow]

then it's miswired in the other end as well

[brittle sparrow]

yep this is inverted too

So white is actually 5v, and red is signal

[thick seal]

This is the one that actually works

So follow this one?

I also had this issue with the wiring that was on the machine

This is the one that is giving me problems and I just swapped the wires

That's did the trick

Ugh I had trusted what the PO had done was correct

[brittle sparrow]

yes

[brittle sparrow]

good 👍

[thick seal]

I went back and looked at the last owners cfg and he used sensorless homing. I guess this is why

[brittle sparrow]

Hehe he probably couldn't figure out why his endstops didn't work 😂
