I can't setup katapult on my printer anymore | VORONDesign | Page 1

dense garden Jan 28, 2024, 3:13 PM

#

So i've had the issue everyone is having right now. My setup is an octopus pro, an ebb36 sb2209 rp2240, and a btt pi.
I didn't realise it at first, but my board came preflashed with canboot (so katapult), and I realise now I could've used this to update my motherboard instead of redoing the entire thing.
Anyway, I am following
https://github.com/Esoterical/voron_canbus/tree/main/mainboard_flashing
I'll try to cite my every steps, so it is easier for you to debug.
Here is my make menuconfig from katapult. My first question is: should the communication interface be set on usb or can? considering i will set it as a can bridge. The guide state USB, but maybe this is the source of my problems?
Anyway. I press Q, then Y, then sudo shutdown now. I power off the printer, add the jumper on the octopus pro, and restart the printer. In the meantime, I confirm i have an STM32F446, and that the board is connected on the USB-C port, so PA11-12 https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/blob/master/Firmware/Klipper/README.md
I reconnect via SSH, and do sudo dfu-util -l.
I see the board in DFU, and do cd ~/katapult make sudo dfu-util -R -a 0 -s 0x08000000:force:mass-erase:leave -D ~/katapult/out/katapult.bin -d 0483:df11. I dont change the line, as it's both 0483:df11 and 0x08000000.
As per usual, it starts by saying "dfu-util: Invalid DFU suffix signature", but it then goes successfully..
I do sudo shutdown now, power off the printer after a little while, remove the jumper, and powers it back on.

I connect via SSH again, and immediately run ls /dev/serial/by-id/. I see the board correctly, so I proceed.

make menuconfig``` once again
And you can see again the pictures. Are the interfaces correct? Also, in the guide, it says 
> You want the Processor and Clock Reference to be set as per whatever board you are running. Set Communication interface to 'USB to CAN bus bridge' then set the CAN Bus interface to use the pins that are specific to your mainboard. Also set the CAN bus speed to the same as the speed in your can0 file. In this guide it is set to 1000000.
However, I don't have a can0 at this point.  or rather, i dont know of a can0 file. Could this be the problem ?
Anyway, I do:
-->Q -->y --> make clean --> make
Then `python3 ~/katapult/scripts/flashtool.py -f ~/klipper/out/klipper.bin -d /dev/serial/by-id/usb-katapult_stm32f446xx_3D0023000B50335331383820-if00`
I want to highlight that, for this step, as it is not mentionned, i haven't put the octopus pro in DFU mode. I have done only what I have described and nothing more. It says flash succes, so I then do lsusb, it takes a surprisingly long amount of time to run this, but then tadaaaa: it doesn't show anything can related....

#

Forgot to add: Same if I do ifconfig: there's no mention of can0

#

I have tried to fix this with @timid steeple yesterday, you can find the steps we went through here

THe first step (With katapult) was completely correct, and that's good. The second step, maybe you had an error in your klipper make menuconfig (even though your screenshot is correct, did it save correctly?).
Also, you should have made the /etc/interfaces.d/can0 file by this point, that is on the very first page of the guide before you get to any mainboard flashing stuff. But that wouldn't cause any problems at this stage anyway.
Can you run wget -qO - debug.esoterical.online | sh and post the termbin link it makes?

dense garden

does your octo definitely have "STM32F446" on the main chip?

#

actually, nevermind, it would if that worked with katapult

#

if you remove the DFU jumper (if you haven't already) then press the reset button once on the octopus, does it show to lsusb ?

dense garden Jan 28, 2024, 8:41 PM

#

hold up, i just realised there are two buttons

#

#

is it he one above the usb c cable, or the on above the usb a cable ?

timid steeple Jan 28, 2024, 8:43 PM

#

the one above the USB should be the reset button I think

dense garden Jan 28, 2024, 8:43 PM

#

USB A ?

timid steeple Jan 28, 2024, 8:43 PM

#

not sure what that bottom one is

#

above the usb-c, next to the stepper drivers

dense garden Jan 28, 2024, 8:43 PM

#

okay, then that is the one i've used

#

timid steeple Jan 28, 2024, 8:44 PM

#

still nothung. OK can you double-click that button then lsusb?

#

double-click should put it back into katapult mode

dense garden Jan 28, 2024, 8:45 PM

#

timid steeple Jan 28, 2024, 8:46 PM

#

dense garden

sweet, does ls /dev/serial/by-id show the katapult ID again?

dense garden Jan 28, 2024, 8:46 PM

#

yes !

timid steeple Jan 28, 2024, 8:46 PM

#

if so, can you cd ~/klipper and make menuconfig and screenshot it again please?

dense garden Jan 28, 2024, 8:47 PM

#

timid steeple Jan 28, 2024, 8:47 PM

#

dense garden

ok, hit Q to save and quit, then make clean then make

dense garden Jan 28, 2024, 8:47 PM

#

Also

#

if you want to make sure yourself that it is indeed an stm32f446
Obvisouly.... the picture has to be flipped hahaa

timid steeple Jan 28, 2024, 8:48 PM

#

then run the "flash klipper via katapult" command:
python3 ~/katapult/scripts/flashtool.py -f ~/klipper/out/klipper.bin -d /dev/serial/by-id/your_katapult_id
replacing the your_katapult_id with the /dev/serial/by-id ID of your katapult ID

dense garden Jan 28, 2024, 8:50 PM

#

timid steeple Jan 28, 2024, 8:51 PM

#

dense garden

did you definitely do the make clean and make first? before the katapult flash command?

dense garden Jan 28, 2024, 8:51 PM

#

yep

#

I have sent the picture, just in case i did something wrong

timid steeple Jan 28, 2024, 8:51 PM

#

no, that's correct

dense garden Jan 28, 2024, 8:52 PM

#

This is insane, what is wrong with my setup 😅

#

the thing is, It looks like it doesn tsee the can0 file

#

timid steeple Jan 28, 2024, 8:53 PM

#

it should be showing up as a "geschwister CAN adapter" to an lsusb, which it isn't

dense garden Jan 28, 2024, 8:53 PM

#

I have seen some architecture changes when it comes to BTT pi, could this be it ?

#

also, i haven't touched the setup, so everything is still wired up, if that matters

timid steeple Jan 28, 2024, 8:53 PM

#

if you have no CAN USB adapter showing then it won't show teh can0 network

dense garden Jan 28, 2024, 8:53 PM

#

okay, its good to know

#

but then, what does it mean? the flashing didn't succeed? the klipper service hasn't launched ? it has but it is not recognized?

timid steeple Jan 28, 2024, 8:55 PM

#

one thing we can try (to just rule out katapult, even though it looks fine) is to put it back into DFU mode so it shows as an "STM device in DFU mode", then do the klipper make menuconfig again and change it so it shows "no bootloader", then make clean and make and make flash FLASH_DEVICE=0483:df11

#

this will overwrite katapult with straight klipper. If this still doesn't then show up as a CAN adapter in lsusb then I'd say the problem is with the BTT distro on your cb1 or something

dense garden Jan 28, 2024, 8:57 PM

#

I can't help but to notice make clean provided an output this time. Is this because I've changed the menuconfig ?

that's good, it downloaded

dense garden Jan 28, 2024, 8:59 PM

#

but didn't flash, right ?

timid steeple Jan 28, 2024, 8:59 PM

#

it' flashed

#

everything after "file downloaded successfully" you can ignore

#

it's just saying it couldn't "reboot" back into DFU mode orsomething, but we don't care about that

#

what does lsusb show now?

dense garden Jan 28, 2024, 9:00 PM

#

I've run it twice. Once with the jumper, once with the jumper removed. It stills shows as device in dfu mode

#

should i reboot and check again ?

timid steeple Jan 28, 2024, 9:01 PM

#

yeah, reboot

#

removing the jumper won't take it out of DFU, you need to remove jumper and reboot the board

dense garden Jan 28, 2024, 9:02 PM

honestly, not really. As long as you can get to a base linux shell (not the HASS cut down SSH thing they give you). Don't even need klipper or anything on the linux, we just want to see if the "Geschwister CAN adapter" shows up to lsusb

dense garden Jan 28, 2024, 9:04 PM

#

Im not sure I understand what you mean hahaah
I say there would be reconfiguration to do, because I think some of the folder architecture is different on the btt pi. But I may be wrong

timid steeple Jan 28, 2024, 9:05 PM

#

oh, yeah you couldn't put the SD from teh BTT Pi into a "normal" pi. I thought you were going to just grab teh home assistant Pi as-is and plug the octo into it

#

what does it show up as in lsusb after the reboot?

dense garden Jan 28, 2024, 9:06 PM

#

sorry for the wait, its still coming

#

i did a reboot instead of a power off and power on

#

not lookjing great...

timid steeple Jan 28, 2024, 9:06 PM

#

yeah nothing. I suspect that BTT pi distro is misbehaving, doesn't have the drivers for a CAN network maybe?

#

probably worth googling around/asking about/seeing if there is a newer linux version on teh BTT github or something

dense garden Jan 28, 2024, 9:07 PM

#

Im not sure i understand what you mean , how can I check if it has the drivers for CAN network?

#

also

timid steeple Jan 28, 2024, 9:07 PM

#

I'm not saying that's the problem, just something like that maybe, I truly don't know

dense garden Jan 28, 2024, 9:08 PM

#

As mentionned yesterday: my printer was working great until the update. It was flashed using canboot. I know canboot is katapult, BUT, the folder is still there, maybe I can try to use what's there to recreate the condition it was flashed with ?

#

I didn't update the canboot folder

timid steeple Jan 28, 2024, 9:09 PM

#

dense garden I didn't update the canboot folder

nah, nothing to do with canboot/katapult. 1. you had katapult installed fine before and 2. now we don't have katapult on there at all and it still doesn't show.
I'd say the distro upgrade did something to break it

#

Probably worth going back and putting katapult back on (like you had done before you opened this ticket, it looks like it was all good) and then flashing klipper to it again the same way you did the first time (but change the klipper menuconfig to have 32KiB bootloader offset again)

dense garden Jan 28, 2024, 9:10 PM

#

distro upgrade = klipper update ?

timid steeple Jan 28, 2024, 9:11 PM

#

dense garden distro upgrade = klipper update ?

if you pressed the "update all" button in mainsail then it'll update klipper and stuff, but also update/upgrade the linux distro itself on the pi

dense garden Jan 28, 2024, 9:11 PM

#

But, I never managed to do it

#

I bought the kit from siboor, and the octopus and the btt pi can pre flashed, I don't know how they did it

#

I have flashed multiple skr pico and skr mini, it never had can, and it never was with a btt pi, its why it's driving me insane, I can't make it

Maybe I should reuse the rpi4 of HASS and start over ?

if you are happy to do that, running a "real" Pi and Raspberry Pi OS (or MainsailOS) makes it a lot easier to know what's going on. For me anyway.

When you flashed it before with "no bootloader" selected in the Klipper menuconfig? That was flashing without katapult. When you use those settings it overwrites any bootloader (like katapult) that is there and has only Klipper firmware There

The weird thing is, the firmware of the cb1 hasn't been updated (at least on the github page). SO maybe there is a compatibility issue with the new klipper firmware that needs to be adressed by BTT.

I can't use katapult to flash or update my octopus pro and my ebb sb2209 rp2040, and apparently, the probleme doesn't come from katapult

#

We 've tried a lot of things to figure it out with esoterical, like by using the reset button on the mcu to force the mcu into dfu (i think) and check the lsusb at everystep, but it never appears as a can bridge
We have tested without katapult as a bootloader, and it still won't work

paper spoke Jan 29, 2024, 6:12 PM

#

I mean, weird, but in terms of getting a working printer, can't you just dfu flash everything then?

dense garden Jan 29, 2024, 6:12 PM

#

Before I answer this, let me tell you I am completely new to CAN bus, so it's possible that I'm unaware of other ways but

#

if im not mistaken, we have tried without katapult as a bootloader, so isn't it equivalent to just dfu flash everything ?

Maybe, probably, but im sure you can recognise that "I can't use katapult" and "I can't get my ebb to flash by any means" are very different statements

dense garden Jan 29, 2024, 6:14 PM

I bought my kit from siboor, everything came pre flashed, so that's also why I have no experience in flashing both the toolhead and the octopus pro to work in can

But, out of curiosity, what is the purpose of having the octopus on katapult ? Simply to avoid openning the eletronic bay and adding a jumper ? or is this a "colateral" bonus ?

paper spoke Jan 29, 2024, 6:23 PM

#

Basically just that, yes. Once you are using the octopus in can bridge mode, getting it back into dfu for an update involves physical access, which is annoying

dense garden Jan 29, 2024, 6:55 PM

#

nvm i missed a word

#

paper spoke Jan 29, 2024, 6:56 PM

#

Damn it

#

Sorry

#

I skipped a step

#

Could you do that again, but without the boot jumper please?

#

I was looking for what if anything shows up in NORMAL mode...

dense garden Jan 29, 2024, 6:58 PM

#

it is still going on, should I let it go ?

paper spoke Jan 29, 2024, 6:58 PM

#

Huh.

#

Well, as silly as it sounds...could you try a new usb cable? Most of the time, that particular error is the cable

#

Though I have no idea why the new firmware would trigger that more

dense garden Jan 29, 2024, 6:59 PM

#

also, I don't know how much you've read of the apst messages, but I have 100+ hours with the machine, I didn't touch the usb cable

#

i will still try a new one though, just to make sure

#

I just need to find one That I know transfers data

paper spoke Jan 29, 2024, 7:00 PM

#

I hear you, I honestly do. But I also know that message is ...almost always...cabling

#

So we gotta at least rule it out

dense garden Jan 29, 2024, 7:01 PM

#

Totally, it happened on my v0 once, a bad usb cable

#

same command ?

paper spoke Jan 29, 2024, 7:02 PM

#

Ya, sounds good

dense garden Jan 29, 2024, 7:03 PM

#

same... It is a cable I used with my keyboard,so it should be able to transfer data

paper spoke Jan 29, 2024, 7:03 PM

#

Well then

dense garden Jan 29, 2024, 7:04 PM

#

Actually, wait a second

paper spoke Jan 29, 2024, 7:04 PM

#

Hmm?

dense garden Jan 29, 2024, 7:04 PM

#

Ive plugged my phone to my pc with this cable, I dont have the notification about data transfer

#

okay, its just my pc, I took my laptop and it does work ( my usb connection started bugging on my pc after trying to reflash an sd card for the btt pi, i probably need to reboot it)

paper spoke Jan 29, 2024, 7:07 PM

#

Just for curiosities sake, if you build the firmware for regular usb, rather than can bridge, does it work any better?

#

(I know it doesn't help with the toolhead, but...)

dense garden Jan 29, 2024, 7:09 PM

#

yeah sure, I understand where the idea is coming from, im doing it right now and Ill let you know

#

I dont know if I should be happy or sad ahaha

paper spoke Jan 29, 2024, 7:10 PM

#

Huh. Very interesting

dense garden Jan 29, 2024, 7:11 PM

#

I have seen issues where people couldn't see their mainboard after setting them as can bridge, because of the can bus speed

#

Let me check If I dont have a 0 missing or one too many...

paper spoke Jan 29, 2024, 7:12 PM

#

When usb isn't establishing the low level connection, we're nowhere near a point that can speeds should impact anything

dense garden Jan 29, 2024, 7:12 PM

#

okay

#

so what do you think it could be then ?

paper spoke Jan 29, 2024, 7:13 PM

#

I have absolutely no idea

#

What klipper version are you on?

dense garden Jan 29, 2024, 7:14 PM

#

but it is a software issue right? not hardware ? or you dont know either ?

#

paper spoke Jan 29, 2024, 7:15 PM

#

I can imagine scenarios either way honestly

dense garden Jan 29, 2024, 7:16 PM

#

@real sinew mentionned here that he went back to klipper v0.11 until the issue is resolved. This could be worth checking? this would definitely tell us if it's software or not

paper spoke Jan 29, 2024, 7:16 PM

#

I certainly wouldn't go that far back

#

But a small Rollback probably isn't a bad idea to try

dense garden Jan 29, 2024, 7:17 PM

#

well, to the last version it was working with, I dont know which it was

#

However, I dont know how to do this 😅

paper spoke Jan 29, 2024, 7:19 PM

#

Actually, before we try moving backwards, why don't we try forwards?

#

Why don't you go ahead and just update that, see if that changes anything?

dense garden Jan 29, 2024, 7:21 PM

#

but, isn't it up to date?

paper spoke Jan 29, 2024, 7:23 PM

#

Doesn't appear to be, no

(Hit check for updates)

dense garden Jan 29, 2024, 7:24 PM

wow, so you are telling me an update JUST got out ? 😂
ill update it

paper spoke Jan 29, 2024, 7:25 PM

#

No, I'm telling you you're a couple of months behind right now actually

#

Which is normally fine of course

#

I've never been one for the "must grab every single update"

dense garden Jan 29, 2024, 7:26 PM

#

But that;s weird considering I have just flashed the sd card, is this normal?
In the meantime, im doing the menuconfig. WIth or without bootloader?

paper spoke Jan 29, 2024, 7:26 PM

#

Completely normal

#

You think btt updates that disk image every single time Kevin pushes a one line change to klipper?

dense garden Jan 29, 2024, 7:27 PM

#

No, rather that when I boot klipper, it automatically checks for update, but you are totally right ! My disk image is back from july, if im not mistaken

paper spoke Jan 29, 2024, 7:28 PM

#

Ya, that's a little odd. Not sure why it hadn't checked automatically

#

Maybe it only does that when klipper is actually behaving or something?

dense garden Jan 29, 2024, 7:29 PM

#

I have just realised

paper spoke Jan 29, 2024, 7:29 PM

#

Anyway. You're stuck in without bootloader for now, until such time as we actually do jam a bootloader back onto that board

dense garden Jan 29, 2024, 7:29 PM

#

WHen I assembled the kit, it had some weird version of klipper or idk. I can't recall but something was odd and I had to change the update manager, we didn't check if this was correct ?

#

( i can't remember what it was exactly)

paper spoke Jan 29, 2024, 7:30 PM

#

Err?

#

Well...on my machine that's not on mainline klipper, there's a warning about it in update manager

#

Yours doesn't have that warning, so I think it's fine...

dense garden Jan 29, 2024, 7:31 PM

#

#

#

I think it was the mainsail config actually

paper spoke Jan 29, 2024, 7:33 PM

#

Alright, well, should be okay

#

Fire off that firmware and let's see if anything changes

dense garden Jan 29, 2024, 7:33 PM

#

I already made the flash, if thats what you mean

#

the above is after flashing

paper spoke Jan 29, 2024, 7:34 PM

Oh, damn

dense garden Jan 29, 2024, 7:34 PM

..backward ?😅

paper spoke Jan 29, 2024, 7:34 PM

#

I just didn't realize what I was looking at

dense garden Jan 29, 2024, 7:34 PM

#

but im not surpsied, i got the error everyone is having after updating klipper, like on friday

#

so I had little hope that updating this new sd card would change anything, as its probably the same update

paper spoke Jan 29, 2024, 7:35 PM

#

So strange

dense garden Jan 29, 2024, 7:35 PM

#

paper spoke I just didn't realize what I was looking at

yeah don't worry, I should've been more specific

paper spoke Jan 29, 2024, 7:36 PM

#

Honestly, I'd be tempted to just buy a u2c

#

You shouldn't have to. I'm a very happy can-bridge user myself. But....

dense garden Jan 29, 2024, 7:37 PM

#

Yeah, I'd hate to do it, that would mean 2-3 weeks of wait, and we wouldn't be sure it would work

#

Can we try going backward with klipper ?

#

Is there somewhere, in the filesof the btt pi, where I can find a history of the version I've used? if so, we could go back to this specific version

paper spoke Jan 29, 2024, 7:38 PM

#

Well, definitely not now that you've reimaged...

dense garden Jan 29, 2024, 7:39 PM

#

As mentionned, this is a new sd card. I did this on purpose to keep everything intact on the other one

paper spoke Jan 29, 2024, 7:39 PM

#

Oh.

#

Hmm. There probably is some way to ask git to tell you. I don't know it though.

dense garden Jan 29, 2024, 7:40 PM

#

Otherwise, its maybe not too important, we can just rollback to the version before

paper spoke Jan 29, 2024, 7:40 PM

#

Hey @quasi thicket. You got any git tricks for finding out what specific versions have previously been on a machine?

quasi thicket Jan 29, 2024, 7:40 PM

#

git reflog of course

dense garden Jan 29, 2024, 7:41 PM

#

THe speed of the man is uncontested

#

Let me switch sd card and ill do that

#

actually, before this, theres maybe a tiny detail that may be important? idk

#

My klipper screen never did this when shutting down

paper spoke Jan 29, 2024, 7:43 PM

#

That's just the same stuff we were retrieving from dmesg

#

It also goes to the console

#

(Which is just hidden until klipperscreen shuts down)

dense garden Jan 29, 2024, 7:43 PM

#

okay, then nothing new there

paper spoke Jan 29, 2024, 7:43 PM

#

Nope

dense garden Jan 29, 2024, 7:46 PM

#

Im guessing thats not how you use it

#

okay got it

#

I have to do git checkout HEAD@{1}, is this correct ?

quasi thicket Jan 29, 2024, 7:55 PM

#

dense garden I have to do git checkout HEAD@{1}, is this correct ?

you could also use the git commit ID like git checkout b50d6669

#

but git will warn you that it's not ideal, you probably want something like git checkout -b recovery b50d6669

#

(which will create a new local git branch called "recovery", from that git commit)

dense garden Jan 29, 2024, 7:56 PM

#

and with this, it's done ? because it was super fast,

#

like as fast as make clean

quasi thicket Jan 29, 2024, 7:56 PM

#

yeah, that should be pretty quick

#

git is usually pretty damn fast when it doesn't have to talk to a server

dense garden Jan 29, 2024, 7:57 PM

#

nice, then Ill try reflashing the octopus pro with this verison, and we shall be fixed

#

it did not... What the hell

dense garden Jan 29, 2024, 7:59 PM

#

quasi thicket yeah, that should be pretty quick

but is it normal that here, it still mentions the other version ?

quasi thicket Jan 29, 2024, 8:00 PM

#

dense garden but is it normal that here, it still mentions the other version ?

I wouldn't worry about whatever Mainsail says

#

it pokes at the git repo when it starts up and doesn't update that info unless you restart it or it performs an update itself, I think

dense garden Jan 29, 2024, 8:00 PM

#

okay, then Ill try an older version again

#

can I keep the name recovery ?

quasi thicket Jan 29, 2024, 8:01 PM

#

you can't do the same git checkout to create it (because it already exists now), but instead you could try git reset --hard <next-git-commit-ID>

dense garden Jan 29, 2024, 8:02 PM

#

okay, thanks

#

still not.... I dont know what else to do now

paper spoke Jan 29, 2024, 8:08 PM

dense garden Jan 29, 2024, 8:08 PM

please tellme, im getting desperate

paper spoke Jan 29, 2024, 8:08 PM

Strip the octopus down. Disconnect the canbus

dense garden Jan 29, 2024, 8:09 PM

#

You mean only remove the canbus from the octopus, or everything ?

paper spoke Jan 29, 2024, 8:09 PM

#

This is what I'm debating honestly

#

Why don't we start small

#

Just do canbus, since our problem seems canbus related

#

But you can be sure that if that doesn't change anything, my next move will be everything except power and usb

dense garden Jan 29, 2024, 8:11 PM

#

alright, its unpluged

#

I still try with the can bridge make menuconfig ?

paper spoke Jan 29, 2024, 8:11 PM

lsusb should be sufficient test wise

even the power cable? toward the bed and stuff

Everything except the power in

okay, let me grab my label printer first

dense garden Jan 29, 2024, 8:27 PM

#

paper spoke Everything except the power in

#

there it is, all naked, except for the power cable. Thers the power cable for the bed left, but its more about safety, cause i dont trust myself

#

as soon as you confirm its all good, ill power it on and do lsusb

paper spoke Jan 29, 2024, 8:29 PM

#

Alright, sounds like a plan

dense garden Jan 29, 2024, 8:30 PM

#

uhhh apparentlz my jumper was still on.... so i dont kow how relevant the past result were...

#

by past result, i mean the very last one

#

oh boy

#

It breathes !

#

Ill replug everything except for the canbus and try again, or do you have another plan ?

paper spoke Jan 29, 2024, 8:33 PM

#

I'd probably replug in groups

dense garden Jan 29, 2024, 8:33 PM

#

Okay, so the easiest first, the motors, as they dont really provide data to the octupus

#

then the fans, then the thermistor

#

then the led, and finally the can ?

paper spoke Jan 29, 2024, 8:33 PM

#

Makes sense to me

dense garden Jan 29, 2024, 8:33 PM

#

and I power off between each trials ?

paper spoke Jan 29, 2024, 8:34 PM

#

Yes. You should always be powered off when doing hookups

dense garden Jan 29, 2024, 8:36 PM

#

motor s: still good

#

fan: still good

#

thermistor: still good

#

aaaaaand led still there. Let's try again with the can bus cable i guess

#

aaaaaaand it's gone

#

so what does it mean ?

paper spoke Jan 29, 2024, 8:47 PM

#

I mean, I think it means something about the canbus cable is preventing the octopus from initializing properly

#

Which is kinda weird

#

I guess I'd try unplugging the OTHER end. Let's find out if the issue is the cable itself, or the board at the far end....

dense garden Jan 29, 2024, 8:49 PM

#

it works

#

I know you have probably explained it already, but as this is new to me, im kind of lost, but could it be that the toolhead use katapult as a bootloader, and not the octopus pro ?

#

and because of this, there's a communication issue that voids everything?

paper spoke Jan 29, 2024, 8:51 PM

#

I don't see how no

dense garden Jan 29, 2024, 8:51 PM

#

Because initially, it was all flashed through canboot. Then I tried reflashing the mainboard, with katapult, so a newer version of canboot, and suddently, nothing works anylonger

paper spoke Jan 29, 2024, 8:51 PM

#

Honestly, something else happened in there

#

Probably not intentionally

dense garden Jan 29, 2024, 8:52 PM

#

On a side note, I guess I can finally close the electronic bay and put back the printer?

paper spoke Jan 29, 2024, 8:52 PM

#

Let's just stop and talk about bootloader for a second

dense garden Jan 29, 2024, 8:53 PM

#

oh, I should also try to rebase klipper to the newer version now i guess

paper spoke Jan 29, 2024, 8:53 PM

#

so the bootloader is a very simple piece of software

#

all it does, is look when the board first starts, and check whether whatever thing (boot jumpers etc) is telling it to go into bootloader mode or not. If yes, it starts communicating on the appropriate interface, listening for firmware to be sent to it. if NOT, it just bails out. hands over control of the mcu to klipper (or whatever other software)

#

so once that handoff happens, the bootloader has absolutely no bearing on the further activity of that board

dense garden Jan 29, 2024, 8:55 PM

#

and katapult is a bootloader, is that correct?

paper spoke Jan 29, 2024, 8:55 PM

#

correct

dense garden Jan 29, 2024, 8:56 PM

#

but if I dont see the printer in lsusb, could it mean it hasn't passed the bootloader? as it neither went in dfu mode, nor handed out the control

#

like if for some reason, it was just stuck in the bootloader

paper spoke Jan 29, 2024, 8:56 PM

#

so get rid of the concept of "the printer"

#

because we need to be thinking in smaller increments than "the printer"

#

we're talking about individual boards here

dense garden Jan 29, 2024, 8:57 PM

#

sorry, it was out of habits, i meant the octopus pro

paper spoke Jan 29, 2024, 8:57 PM

#

your main mcu is ending up in some kind of strange state, yes

#

but that mcu doesn't currently have a bootloader installed

#

so it can't be getting stuck in what isn't there

dense garden Jan 29, 2024, 8:58 PM

#

got it

paper spoke Jan 29, 2024, 8:58 PM

#

(I'm technically oversimplifying. dfu mode is also a boot loader, but it's a factory installed one that we can't alter. it shouldn't have much relationship to this)

#

is it possible that your toolhead board is doing ...something incredibly bizarre that's preventing the main mcu from initializing? ...maybe. though I have very little idea what that would be

#

which is why I want to test with the wire connected, but the toolhead board disconnected

dense garden Jan 29, 2024, 8:59 PM

#

to eliminate this, we should try to reflash the toolhead too

#

but

paper spoke Jan 29, 2024, 8:59 PM

#

yes. but let's try the physical thing first

dense garden Jan 29, 2024, 9:00 PM

#

i never managed to put it into dfu mode, or at least visible. Altought, I assumed I couldnt see it because the can bus bridge wasn't set up

paper spoke Jan 29, 2024, 9:00 PM

#

there's no scenario where dfu cares about canbus

#

dfu is a usb tool (well, and serial,but lets ignore that)

dense garden Jan 29, 2024, 9:00 PM

#

but the toolhead communicates through can ? so if there's no can, the mcu cannot see the toolhead in dfu mode, right ?

paper spoke Jan 29, 2024, 9:01 PM

#

you're conflating unrelated things again

dense garden Jan 29, 2024, 9:01 PM

#

😅

paper spoke Jan 29, 2024, 9:01 PM

#

the toolhead communicates over can in normal usage yes

#

the toolhead also communicates over can when we're flashing it via Katapult

#

that functionality is essentially why katapult exists

#

however

#

when we're flashing a board (no matter what board. toolhead or octopus) over dfu we need a usb connection

#

dfu is also our get-out-of-jail-free card though. because it's a factory burned in thing that can't be altered... it always works no matter how you've managed to scramble the software

dense garden Jan 29, 2024, 9:04 PM

okay

but wehen you say usb connection, you mean through usb port right ?

#

or can the can cable act as a usb connection too ?

paper spoke Jan 29, 2024, 9:05 PM

#

Yes, I mean with a usb cable

#

You will need to take an extra USB cable, and temporarily plug it into the toolhead

#

From the pi to the toolhead

#

But you still haven't done my test (or still haven't told me the results at least)

dense garden Jan 29, 2024, 9:07 PM

#

paper spoke yes. but let's try the physical thing first

what did you mean by the physical thing first ?

#

if thats removing the cable on the toolhead's end, then yes, it works

#

paper spoke Jan 29, 2024, 9:08 PM

#

Okay. Well, fair enough. Toolhead is doing *something * crazy then

#

So okay. Get a usb hooked up to it, and put the toolhead into dfu mode

dense garden Jan 29, 2024, 9:11 PM

let me just check if I did it correctly. I pressed both buttons while plugging the usb c cable

I don't think it has to be all at once with those

dense garden Jan 29, 2024, 9:13 PM

Plug in cable first, then hold boot, while tapping reset

dense garden Jan 29, 2024, 9:14 PM

Katapult, followed by klipper

dense garden Jan 29, 2024, 9:18 PM

paper spoke Jan 29, 2024, 9:19 PM

#

No

#

We don't want to go VIA katapult (at least not for the first step]

#

But we do want to INSTALL katapult, so you can use it in the future

dense garden Jan 29, 2024, 9:20 PM

i think I understand the difference

but just to make sure, i do cd ~/katapult make menuconfig as per esoterical guide

#

correct?

#

Yes

dense garden Jan 29, 2024, 9:24 PM

#

Is this corect? I followed the images from the link I've provided

#

this is the katapult make menuconfig

#

What I find weird is the CAN RX gpio number and CAN TX gpio number, I think I should specify a gpio, but btt didn't specify any in their guide

dense garden Jan 29, 2024, 9:42 PM

Okay I went ahead, and it alrady shows when I look for UUID, which is already an improvement

no

#

that's what that bootloader offset setting is all about

dense garden Jan 29, 2024, 9:48 PM

#

ohhh I think I finally understand

paper spoke Jan 29, 2024, 9:48 PM

#

err

#

this is an rp2040, so it's actually NOT going to be dfu

#

it's going to be the rp2040's BOOTSEL or whatever

dense garden Jan 29, 2024, 9:49 PM

#

the offset as in, you want to keep that memory for the bootloader

paper spoke Jan 29, 2024, 9:49 PM

#

same difference though

paper spoke Jan 29, 2024, 9:49 PM

dense garden the offset as in, you want to keep that memory for the bootloader

exactly

dense garden Jan 29, 2024, 9:49 PM

#

okay nice

#

so let me press onthe buttons and we will let the magic do its stuff

paper spoke Jan 29, 2024, 9:49 PM

#

yep

#

press the buttons, and then we'll flash it with make flash (from klipper)

dense garden Jan 29, 2024, 9:50 PM

#

well, that was fast

#

paper spoke Jan 29, 2024, 9:50 PM

#

it is only a like 30k file 😛

dense garden Jan 29, 2024, 9:50 PM

#

How large is the one for the octopus ?

paper spoke Jan 29, 2024, 9:50 PM

#

about the same

dense garden Jan 29, 2024, 9:51 PM

#

uh, oaky, I thought it was a bit longer for the octopus

paper spoke Jan 29, 2024, 9:51 PM

#

probably

dense garden Jan 29, 2024, 9:51 PM

#

shall i power off the printer, replug the canbus, remove the usb c and power it on ?

paper spoke Jan 29, 2024, 9:51 PM

#

different moving pieces there for sure

#

anyway, yes. I think that's the thing to do

#

let's find out if we'

#

if we changed anything useful!

dense garden Jan 29, 2024, 9:52 PM

#

🤞

#

oh my

#

oh

#

#

is it.... finally over?

paper spoke Jan 29, 2024, 9:54 PM

#

Looks promising!

dense garden Jan 29, 2024, 9:54 PM

#

let me plug those UUID in the printer.cfg

paper spoke Jan 29, 2024, 9:54 PM

#

What is a canbus uuid check showing?

#

Is it getting two devices, both running klipper?

dense garden Jan 29, 2024, 9:54 PM

#

#

better

#

1 katapult 1 klipper

#

Hmmm, klipper isn't starting properly i think, It's stuck in
time for a reboot !

paper spoke Jan 29, 2024, 9:55 PM

#

No, that's not better

dense garden Jan 29, 2024, 9:56 PM

#

paper spoke No, that's not better

oh ?

paper spoke Jan 29, 2024, 9:56 PM

#

You should be seeing two klipper devices

dense garden Jan 29, 2024, 9:56 PM

#

ohhhhhhh wait

#

there's the 5v jumper !

paper spoke Jan 29, 2024, 9:56 PM

#

So somebody (and I'm pretty sure it's the toolhead) isn't quite with us yet

#

Maybe flashing klipper on the toolhead with make flash didn't work for some weird reason

#

Pull that jumper, but I doubt it'll change it

#

We may have to try a flash using katapult now....

dense garden Jan 29, 2024, 9:57 PM

#

do I need to redo make clean and make or not ?

paper spoke Jan 29, 2024, 9:58 PM

#

Mmm....shouldn't need to.

dense garden Jan 29, 2024, 9:58 PM

#

#

we were so close

paper spoke Jan 29, 2024, 9:59 PM

#

Hold up, why did you use THAT uuid?

dense garden Jan 29, 2024, 10:00 PM

#

isnt it the one of the toolhead ?

paper spoke Jan 29, 2024, 10:00 PM

#

I wouldn't say so, no

#

That looks like the uuid for the octopus to me

dense garden Jan 29, 2024, 10:00 PM

#

well...

paper spoke Jan 29, 2024, 10:01 PM

#

No shit

#

You just scrambled your octopus

dense garden Jan 29, 2024, 10:01 PM

#

dont tell me i have to start over

paper spoke Jan 29, 2024, 10:01 PM

#

No

#

It's probably fine

#

But slow your roll for a second and consider what you're looking at

dense garden Jan 29, 2024, 10:02 PM

#

well I see the octopus in DFU

paper spoke Jan 29, 2024, 10:02 PM

#

Klipper provides canbus bridge mode

#

Not rhat

#

Before you went and did that

#

Klipper provides bridge mode. Katapult does not

#

So

#

If you're seeing two uuids, one klipper, one not, the ONLY WAY that occurs, is if the octopus is completely happily running klipper (in bridge mode) and the toolhead board is in katapult

dense garden Jan 29, 2024, 10:04 PM

#

but I dont see that anymore, is this an issue ? or will rebooting fix this ?

paper spoke Jan 29, 2024, 10:04 PM

#

So when you're reading the two uuids in that listing, the one that says katapult must be the toolhead

#

Does that make sense?

paper spoke Jan 29, 2024, 10:04 PM

#

dense garden but I dont see that anymore, is this an issue ? or will rebooting fix this ?

Try to focus here.

dense garden Jan 29, 2024, 10:04 PM

#

yes totally, I agree with you

paper spoke Jan 29, 2024, 10:04 PM

#

We're doing understanding right now

dense garden Jan 29, 2024, 10:05 PM

#

the thing is, I prepared the command beforehand

paper spoke Jan 29, 2024, 10:05 PM

#

Once you understand, then we'll solve the problem 😛

#

So yes.

dense garden Jan 29, 2024, 10:05 PM

#

when I was only seeing 1 UUID. As the fact that I was finally seeing a UUID was new, i considered it was the toolhead, so I prepped the command

paper spoke Jan 29, 2024, 10:05 PM

#

I don't think anything has actually been flashed to the octopus

dense garden Jan 29, 2024, 10:05 PM

#

but I agree that in the second picture with the two uuid

#

its absolutely obvious which is the toolhead and which is not

paper spoke Jan 29, 2024, 10:05 PM

#

It just is in dfu mode waiting for stuff to be pushed

dense garden Jan 29, 2024, 10:05 PM

#

there's only one of the two that has katapult. It was just me being too hasty

paper spoke Jan 29, 2024, 10:06 PM

#

So I think a simple reset or reboot will get it back in operation

dense garden Jan 29, 2024, 10:06 PM

#

paper spoke It just is in dfu mode waiting for stuff to be pushed

But how did it go into dfu mode without katapult nor a jumper tho ?

paper spoke Jan 29, 2024, 10:07 PM

#

Klipper is capable of rebooting it into dfu mode

#

And the flashing script must have triggered that functionality

#

Which is actually pretty cool . I didn't know it could do that

dense garden Jan 29, 2024, 10:07 PM

#

Same, I thought that was what katapult was for

#

it works !

paper spoke Jan 29, 2024, 10:08 PM

#

Katapult puts it into katapult flashing mode over usb, which is...same but different. But ya. Til

dense garden Jan 29, 2024, 10:08 PM

#

and it starts of with a bang hahahaa, But I think I know what this is

#

but heym thank you SO MUCH !

#

I truly appreciate the time you've taken to help me there, and I cannot express enough my gratitude toward you

paper spoke Jan 29, 2024, 10:11 PM

#

Hey, you're welcome. That was a STRANGE problem, and I'm glad we were able to run It down

#

(Granted, I still don't know exactly WHAT the toolhead was doing that was breaking things so badly. But...details.)

dense garden Jan 29, 2024, 10:12 PM

#

Im just so happy that you stuck by, because nothing was helping us pin down the issue

#I can't setup katapult on my printer anymore
