🚨 Urgent Help Needed! 🚨 I’m stuck flashing RatOS and could really use an expert hand.Please help🙏

[broken kestrel]

I have this printer that I spent almost $3000 sitting in my basement for months. Someone was nice enough to build it for me, but now they aren’t able to flush the firmware on for me, so I try to do it, but I have no clue how to do it, and I need help. I’ve tried using the Rat OS manual, but I just couldn’t install it. I have zero clue what I’m doing, and if someone could give me step-by-step help, that would be greatly appreciated. I am willing to compensate them in return. I couldn’t figure out how to flash firmware, especially because I’m using a Mac, that might be part of the issue, but it would be great if someone can help me.

EDIT: I have nothing against the RatRig, and I believe they make amazing printers. I just want to get it printing.

[lost orbit]

Get this for Mac
https://etcher.balena.io/#download-etcher

Have you downloaded the RatOS image?

[broken kestrel]

I tried it let me show you what happens

@lost orbit Hold on what RatOS should I download?

Which version should I download?

And also, what file

I could’ve downloaded the wrong file

@lost orbit Which file should I download

What should I do?

[lost orbit]

You want the rpi32.img.xz file. The one that is 1.79 GB

Sorry, I'm out running errands and will reply slowly

[broken kestrel]

I totally understand that’s fine.

[broken kestrel]

@lost orbit I’ll try again using that file.

@lost orbit Now what?

[lost orbit]

I know for PC there is an issue with more recent versions of balena etcher. Didn't think it would extend to Mac but here we are

Try grabbing 1.18, or Google around for a better Mac alternative

[broken kestrel]

@lost orbit Will this work?

[lost orbit]

Yes, but don't change any defaults

[broken kestrel]

is this good?

[lost orbit]

Looks good so far. Hope for no errors 🙂

[broken kestrel]

ill tell you when its done

@lost orbit ITS DONE

What do i do

[timid rock]

I’m assuming the person that built it did not flash the Octopus v1.1 board. You will probably want to put in some ear plugs or disconnect the part cooling fan before you power up, other wise it will run at 100% speed until you get the main board and tool boards flashed. It is really loud.

Eject the microSD card from your computer and install it into the RaspPi.

It will take a few minutes to boot, but you should eventually see a “RatOS” WiFi signal show up on your computer. When it does, connect to it using the password “raspberry”.

From there you should be able to follow the commissioning guide.

[broken kestrel]

@timid rock @lost orbit Where do I put the SD card?

???

[lost orbit]

What have you done to try and find where the microSD card slot is ona raspi?

[broken kestrel]

I don’t see a SD card on the Raspberry Pi.

[lost orbit]

That wasn't my question

[broken kestrel]

I’m sorry I didn’t understand. Can you please explain your question?

[lost orbit]

What steps did you take in order to try and find where the slot on the raspberry pi is for the sd card?

[broken kestrel]

I just looked for a SD card slot.

[lost orbit]

Visual inspection is a good first attempt, for sure. You could then have tried to find more pictures of one, or a diagram.

To cut that short though, i'll tell you it is on the back.

in the top right in the pic to be precise. You may find it easier to unmount it from the electronics panel to see exactly where it is to plug in the sd card.

After the first time you should be able to do it by feel

[broken kestrel]

@lost orbit I inserted the SD card. Now I wait for the hotspot to appear like the instructions say?

[lost orbit]

yep 🙂

[broken kestrel]

@lost orbit OK, but the sd card has been in the Raspberry Pi for over 30 minutes, and it doesn’t show up.

[lost orbit]

do you have it the right way up? it's easy to put in wrong

[broken kestrel]

@lost orbit Is this the correct way?

@lost orbit Still not whowing up?

[lost orbit]

can't tell from the pic, sorry. Try flipping it around and rebooting

Bout to head out for the evening, but I'll try and check in

[broken kestrel]

wrong pic

[timid rock]

Doesn’t look like the card is fully seated in the socket.

I would turn off the power, unbolt the Pi board from the mount so you can flip it over and see how the card is seated.

[broken kestrel]

@lost orbit @timid rock Thanks, I’m not home now, but when I get home, I will finish.

[broken kestrel]

@timid rock @lost orbit OK, I’m back.

@timid rock @lost orbit

[lost orbit]

I'm not near mine to check if it's right. Do yes it go further in, and did you try flipping it around to see if it fit?

[broken kestrel]

🚨 Urgent Help Needed! 🚨 I’m stuck flashing RatOS and could really use an expert hand.Please help🙏

[foggy notch]

You can see the clip there

You were right the first time

[broken kestrel]

THANK YOU

@foggy notch Do you know what I should do since the Raspberry Pi hotspot isn’t showing up?

[foggy notch]

Is the pi getting power?

[broken kestrel]

How do I tell?

[foggy notch]

Should see LEDs

[broken kestrel]

On the raspberry pie?

[foggy notch]

Ye

[broken kestrel]

there is no LEDs showing on the raspberry pi

Now, what do I do? How do I give a power? Can I send a photo of the wiring?

[foggy notch]

Do you have a power supply for it?

Seperate plug in

[broken kestrel]

I did not plug it in. I’ll do it now.

I did plug it into my computer, and it says it takes too much power, but I didn’t realize what It meant.

[foggy notch]

A USB C phone charger will do

Plug everything else out

[broken kestrel]

What do you mean? I should unplug everything?

[foggy notch]

From the pi

Mark those 2 wires hard wired onto it

[foggy notch]

Dont loose track of them!

[broken kestrel]

I should unplug those two

[foggy notch]

Ye

[foggy notch]

Ok it looks somewhat alive

[foggy notch]

👍

[broken kestrel]

I need it to show up on my computer, though.

[foggy notch]

You can login a link it to your wifi

Connect to the hotspot with password

raspberry

[broken kestrel]

It shows on my phone but not on my computer.

Now, what do I do?

And also now I wanted to thank you so much for spending your time to help me do this. I really appreciate it.

[foggy notch]

No worries

Login to the hotspot

raspberry

[broken kestrel]

Now what do I do? I don’t wanna corrupt my SD card

[foggy notch]

Reboot

Click got it

[broken kestrel]

What do I press? reboot what?

OK

now, what do I do?

@foggy notch I Pressed OK and It close the tab

[foggy notch]

Unpower the pi and reconnect the USB cables

Leave the 2 wires disconnected and just use the USB for now

You can mount it back on the printer

[broken kestrel]

Does it matter the order of the USB cables since there are two blue USB-A ports and two black ones

[foggy notch]

Not really

Some trial and error if there are issues down the line with a camera or whatever

https://os.ratrig.com/assets/images/octopus-11-wiring-19beb1b4b4719f7327a629b125c1dade.png

[broken kestrel]

Can I give you a picture of the wiring and you’ll tell me if it’s correct?

[foggy notch]

I dont think it right unfortunately

Or it at least incomplete

[broken kestrel]

My brother is the one who built it and he said he did perfect wiring, and triple checked it

But everyone can make mistakes

This is the board

@foggy notch Is that the same one in the picture?

[foggy notch]

Same ye

Looks like you are missing fans and an endstoo

‘endstop

[broken kestrel]

Can you maybe send me photos for reference because I don’t know what parts I need or what wires I need since as I mentioned it at the beginning of this post I did not build this printer and that’s why I’m struggling with the firmware

[foggy notch]

Does it have a toolboard do you know?

[broken kestrel]

Does what have a tool board?

[foggy notch]

The toolhead

Printhead

[broken kestrel]

How do I check?

[foggy notch]

Ye thats it

Little board on the toolhead

[broken kestrel]

I do have a bunch of printer parts, but that’s for a different project, but I can still use it if I need them

[broken kestrel]

What should I do with it?

[foggy notch]

You can probably go through the steps on the config commissioning now

[broken kestrel]

It doesn’t work when I try clicking on the website the rat rig OS

[foggy notch]

A list of what your ordered will help. You have to tell the ratos what parts are installed

Ratos.local?

[broken kestrel]

It doesn’t work when I try going on these two websites

[broken kestrel]

Like the electronic parts

[foggy notch]

Ye what hotend etc.

[broken kestrel]

I know some of them are the top of my head

[foggy notch]

Just go through it step by step

Use the vcore 4 commisioning too

[broken kestrel]

But I can’t access RatOS.local

[foggy notch]

https://docs.ratrig.com/v-core-4-0/commissioning-guide#C-configuration

[broken kestrel]

Should I plug in the Raspberry Pi?

[foggy notch]

You might need to find the ip of the pi

[foggy notch]

Yes

[broken kestrel]

How?

[foggy notch]

Forget that

Plug it in

[broken kestrel]

So should I unplug everything again?

[foggy notch]

No plug the charger into it

[broken kestrel]

Ok

[foggy notch]

You in?

[broken kestrel]

Is this good it’s flashing red the status icon thing

It didn’t show up in the Wi-Fi yet

[foggy notch]

Once there is no smoke we’re happy

[broken kestrel]

Hold on a minute there might be smoke

That’s not good

[foggy notch]

Click on the configurator

[broken kestrel]

What do I click on?

[foggy notch]

No 🔥?

[broken kestrel]

Nope

No fire or no smoke

[foggy notch]

Ok. The heated bed is cold?

[broken kestrel]

Yes, it is

[foggy notch]

Grand

You need to run the updates next

As per the docs.

[broken kestrel]

Which one do I click on?

[foggy notch]

There is an order to to it

[broken kestrel]

I use this Guide, correct

[foggy notch]

Ye it should be good

[broken kestrel]

That’s not an option

[foggy notch]

https://os.ratrig.com/docs/installation

[foggy notch]

Hit the back button

In the browser

Or just ratos.local

Goes through it all there in the ratOS docs

I’m need to sleep but you are nearly there.

Might be best to commission the electronics with a fresh head.

[broken kestrel]

Thank you so much for all the help and all the time you have gave me I couldn’t thank you enough

I really appreciate it

[foggy notch]

And also someone who owns a v core 4

[broken kestrel]

What do you mean?

[foggy notch]

I have a 3 so slightly different

The guide should be enough though

[broken kestrel]

Wait before you go I have one last question. What website do I use?

[broken kestrel]

This or

[foggy notch]

They updated it this week

The ratrig one

[broken kestrel]

The other one

[foggy notch]

I used both…

[broken kestrel]

Ok

[foggy notch]

They should follow each other roughly!

There are some youtube videos on the vcore 4.

[broken kestrel]

Do I click this?

[foggy notch]

Have a look first

[broken kestrel]

I hope you have a great night. Thank you for your time and effort.

[foggy notch]

I think just do ratos first one sec

Update RatOS packages first.
If you see both ratos and ratos-configurator in the list (RatOS prior to V2.1.0-RC4), start by updating ratos first, then ratos-configurator.
If you see only ratos-configurator (mainsail v2.12 or below and/or RatOS prior to V2.1.0-RC4) or RatOS Core: Configuration & Configurator (mainsail v2.13 and RatOS V2.1.0-RC4 and above) in the list, update only this package.

Rather than update all

[broken kestrel]

OK, I don’t really understand but whatever

[foggy notch]

https://youtu.be/s3E-rlVkJaw?feature=shared

[foggy notch]

Best of luck with it.

[timid rock]

No. Click “Abort”

Scroll on that list and find the one that is labeled “RatOS”. Update only that one. RatOS must be updated first or you have to reflash the card. Old version of RatOS will not recognize the other packages if they go before it and then you are stuck.

[broken kestrel]

UH OH

[timid rock]

If RatOS is still working, maybe it is ok. I have not seen that error before.

Click on the invalid arrow and see what it says

[broken kestrel]

@timid rock @Now what?

[lost orbit]

Reflash the SD card and start over is the easiest

[lavish furnace]

Your pi power was not wired correctly. Sorry just found this post. Should look like below picture

https://ratrig.dozuki.com/Guide/14.+Wiring+Firmware+&+RatOS/167

[broken kestrel]

Oh, you’re forgetting this is the V-Core 4 not the V-Core 3

Does this still apply though

[lavish furnace]

still applies. I'm on vcore4

[timid rock]

Interesting. Must have changed recently. The V-Core 4 I built earlier this year was only two jumpers

[lavish furnace]

The pi 4 has always been 5v power on pin 2 and/or 4. While technically speaking a pi can be powered from only 1 it is not recommended unless you have a dedicated stable 5v supply that can provide constant power without experiencing voltage drop which can occur while running the pi from another circuit board. In this case the octopus board. By supplying power to both you compensate for the potential power drop. Also earlier models of the pi 4 have a poly fuse. By using both pins you bypass said fuse. The pi 4b should not have this fuse and pin 2 and 4 should by physically linked.

[lavish furnace]

Also since it was pointed out that I linked vcore 3 document. Here is vcore4 https://ratrig.dozuki.com/Guide/13.+Wiring/316 steps 38 - 41 has 5v wired same way.

[timid rock]

Looks like I will have to make a couple more power wires. The new kit I received a few months ago also only had one pair. Have only had 2 or 3 instances of “Low voltage throttle” warnings in the 1,500+ hrs we have on the first printer, so far.

I’ll fix the first printer after the second printer is up and running.

[hybrid wagon]

Hello

[potent horizon]

@broken kestrel make sure you use a download manager to make sure you have the complete download with no corrupted files, I had to that extra step of downloading this way because it would fail my download always at 99%

That connection for power on raspberry pi mist also survive vibrations later, I ended up soldering my connections

[hybrid wagon]

im the one building the printer for @broken kestrel

and th eprinter only came with 2 cables for the pie so i cant do what u showed me

im aslo going to flash it for him bc he wawsnt able to secseed

[lost orbit]

Good luck

[hybrid wagon]

would u be able to help

[lost orbit]

What's the current issue you're tackling?

[hybrid wagon]

i only have 2 wires to connect the pie to the motherboard not 4 so what do i do

[lost orbit]

For what, power? What are the connectors?

[hybrid wagon]

yes for power

[lost orbit]

Are you having trouble finding the connectors?

Buy connectors, buy wire, buy crimpers, make your own cable

Or power the raspi over USB

[foggy notch]

You can buy pre made cables.

Female to female dupont

[winter sand]

Hello good people! I am now starting to build my vcore4 electronics and I am seeing some trouble with ratOS and rpi5... I choosed that one exactly... Is there support for that rpi? Any good will help.

[lost orbit]

No, ratos is not built for raspi5

If you have other questions, please open your own thread

[hybrid wagon]

what shoud i put in this config

[lost orbit]

which part?

I know you didn't build the machine, but you do have it in front of you, yes?

And hopefuly the order form?

[hybrid wagon]

i did build it but i just want the exelaroniters and endstops

[lost orbit]

So which part are you having trouble with?

What shows up in the list?

[foggy notch]

Accelerometer?

[hybrid wagon]

i just want to kwon what to put in

can u plz inform me

[lost orbit]

No, because I don't know what you have

[hybrid wagon]

how can u help

[lost orbit]

Ask specific questions, and have knowledge of what your machine is equipped with.

[hybrid wagon]

i ma also triing to reconetct to it how do i do that?

[lost orbit]

What are you trying to connect to? How are you trying? What error messages are you getting? What is the screen you expect to see?

[hybrid wagon]

in just trying to connect to the printer where do i go to do so thx for the quick response

[lost orbit]

If you haven't connected it to your wifi, then you should be able to see it making a hotspot. Do you see it in your list of wifi?

[hybrid wagon]

yes

[lost orbit]

Follow these instructions carefully.
https://os.ratrig.com/docs/installation#wifi-or-ethernet

[hybrid wagon]

nvmd i its not showing up

[lost orbit]

Is it turned on?

[hybrid wagon]

yes

[lost orbit]

Try opening a browser and opening http://ratos.local/configure

[hybrid wagon]

i could be bc i was in middle of what is end earlyer and the pi got unplugged is that an issue

[lost orbit]

It could cause issues, yes

If it isn't creating the ratos hotspot, and it isn't connecting to your wifi, then I would reflash it.

[hybrid wagon]

ok

[lost orbit]

I'm headed to bed, good luck

[hybrid wagon]

im stuck here i tried loading the beacon in config but it still keep sending me tonthis screen

[hybrid wagon]

?

[timid rock]

Most of the time that is the connector not being installed fully.

[lost orbit]

Do you mean in the configurator?

[hybrid wagon]

Yes, the configurator

[lost orbit]

Is the beacon plugged in? Does it have a light?

[hybrid wagon]

Yes but idk what u mean by the light

[lost orbit]

I believe the beacon has a small led that will light up if it is powered

[hybrid wagon]

yes that was the issue i think but now its shoing this😩

[timid rock]

Did you or @broken kestrel add anything to the RatOS.cfg?

[rotund matrix]

That line should be in printer.cfg not Ratos.

[broken kestrel]

I did not

[broken kestrel]

What should i press?

[hybrid wagon]

anyone know what to do

[timid rock]

It seems like it doesn’t like that line of code. I’m not sure if that is telling you it is in RatOS.cfg or if that RatOS is a sub section in printer.cfg.

RatOS.cfg should never be tampered with. All code overrides need to be in printer.cfg

If anything was added to allow unsupported slicer code, I would remove the lines added, then save & restart.

[lost orbit]

might also just need to update some stuff, but should be done in the right order.
Can we get a screenshot of the Update Manager?

[lost orbit]

Start over with flashing. Not sure what you did to get those in an invalid state.

[foggy notch]

It was never confirmed if it was re flashed after hitting ‘update all’

[foggy notch]

You need to follow the instructions in the docs.

Update RATOS and the configurator first essentially.

[lost orbit]

2. Connect to hotspot
3. Setup wifi through configurator (and let it reboot)
4. Go to /config
5. Refresh update manager
6. at this point nothing should be invalid, all green. IF THAT'S NOT THE CASE stop here and post your moonraker.log
7. Update only the RatOS package(NOT configurator).
8. Update RatOS configurator (this takes awhile, if the mainsail output of the update process hangs, let it sit for 10 minutes and then refresh the page, Ctrl+Shift+R)
9. Restart moonraker service (click power icon in the top right of mainsail, click the refresh button next to moonraker under "service controls")
10. Reload mainsail (Ctrol+Shift+R)
11. Refresh update manager
12. "RatOS" should be gone from the list. Everything should be green and have several updates except RatOS configurator (ignore the klipper errors). If it's not, stop here and post your moonraker.log.
13. Click update all.
14. Done.```

[hybrid wagon]

how do i post my moonraker.log

[rain nova]

Get ratos-debug.zip under configurator.
Everything is included there.

[hybrid wagon]

@lost orbit this is insane. I have flashed my printer over 20 times and keep just getting these stupid errors.

[lost orbit]

that error is easy, the extruder thermistor either isn't plugged in, or has the wrong type selected. Likely the latter.

[timid rock]

Or the jumper is not installed

Could also be a damaged/poorly connected wire for the thermistor. I have replaced 3 from the wire breaking where it goes into the hot end block.

[hybrid wagon]

what jumper

im having so much truble with this printer is this usual

ive had this built for months now but have never used it

[lost orbit]

That says the raspi isn't hooked up to the mainboard.

[broken kestrel]

Anyone able to help?

[foggy notch]

Did you reflash the OS to the SD card after you incorrectly hit ‘update all’ on initial startup?

[broken kestrel]

I’m currently on vacation. Sam Scam will continue this when I get back.

[broken kestrel]

I am back

[broken kestrel]

Sam Scam is the one building/flashing the printer

I am not

Can somone tell me all the parts that are broken?

[lost orbit]

At this point I don't trust any part, nor anyone that has had their hands on it.

[broken kestrel]

what do you mean?

Sam Scam is my brother. He is now flashing that he told me parts are broken, and now I am asking what parts are broken.

[broken kestrel]

@lost orbit Why

[lost orbit]

Too many errors, responses from everyone have been slow, and lacking detail. Questions asked show a lack of knowledge of printers, klipper, or how to read documentation. I realize this is going to be rude, but I've washed my hands of this thread weeks ago.

[broken kestrel]

I own and bought the printer my brother built for me and is now flashing it for me.

However, he does take forever to get things done, so that’s why you experienced these issues. I apologize if I caused you any trouble.

What do you suggest I do now?

[lost orbit]

Read documentation, test assumptions.

[broken kestrel]

I will do as you said

How long does it take to flash?

@lost orbit
 Because my brother flashed, should I restart everything or continue where he left off? Right now, I see this.

[lost orbit]

What does that error message mean to you? Do you have any guesses?

Have you tried googling it?

[broken kestrel]

Yes, I just don’t know where the thermistor is.

[broken kestrel]

I assume the problem is based on the thermistor not being plugged in or it being broken.

[lost orbit]

those are the most likely, yep

[broken kestrel]

@lost orbit Would you be able to help me find the thermistor? I cannot find it.

[broken kestrel]

?

[foggy notch]

what hotend do you have?

[broken kestrel]

Rapido Phatus 2

[foggy notch]

google that + thermistor/diagram etc. until you find what you need.

[broken kestrel]

ok

[fierce ore]

I'm curious,is he still alive or did he burned the house down? Is the printer printing now?

[broken kestrel]

@fierce ore No it’s not printing
