Weve been using the M8P Motherboard with CB1 and Canbus Wiring System with EEB2209. Weve been following the build guide and since yesterday were setting up the software. We setup the main MCU canbus mainbus adapter. It shows up on the scan with Klipper.
biqu@VORON-PRINTER:~$ python3 ~/Katapult/scripts/flashtool.py -i can0 -q
Resetting all bootloader node IDs...
Checking for Katapult nodes...
Detected UUID: 9f39ef3a91eb, Application: Klipper
CANBus UUID Query Complete
biqu@VORON-PRINTER:~$
We unfortunately also dont have a multimeter to verify that the resistors are correctly and displaying the correct values. Yet we tripple checked and they should be correct. the wires also arent the issue. Were also kinda running out of options. We tried the canbus.esoterical guide all of the thingies that are relevant to our knowledge and yet we cant find it.

does it turn on? any lights?

The ebb sb2209 has a constant green light and a slow blinking red Light after I had flashed katapult on it via usb

yeeeeees
its very unfortunate ive got it in september and then built it to the tap head and then decided to wait for minecat to come here. weve spend the last 3 days putting in the electronics and finally thought we were close to finishing when this issue started to arrise

hmm appears like maybe we should just reset all and retry

Its not uncommon for errors when inputting the correct setting.
I would highly recommend following this guide and asking for help if you can’t find the info you need.

Did you use the correct MP8 settings? There are 2 version and we see it all the time people either use the wrong ones or get a letter wrong in the communication setting. It's worth going through the process again to double check.

Yea I used the m8p V2.0
Because that's the one I have
I used these:

He got those from youtube
dusky coyote
None of those links work
dusky coyote
Right well you either need to try it again or at least start posting some pictures and more info.
dusky coyote
Picture of the mainboard (MP8) pictured of the EBB board, the wiring
dusky coyote
ideally screenshots of the setting used from your actual printer.
rapid bobcat
Ok. gimme a moment
here. its a lil hard to take pics of the toolhead rn. do those suffice?
dusky coyote
Where is the 24v and GND wires for the CAN cable plugged in?
soft birch
its plugged into the powersupply
dusky coyote
Is it those to wires with no connector on?
rapid bobcat
soft birch
Is it those to wires with no connector on?
yea
dusky coyote
Can this be changed to have connectors on? Just so we know we get a good connection and it's safer.
soft birch
yea il do that
dusky coyote
The wiring (apart from above) looks good. So I now need to see the setting currently in the firmware on the boards.
soft birch
ok
rapid bobcat
Ill turn it on
dusky coyote
Are these the actual setting on the boards in @rapid bobcat printer or a screenshot from elsewhere?
soft birch
thats the actual settings
dusky coyote
And which EBB board is it specifically?
And is the printer powered on now and can I get a picture of it.
The toolhead board that is
The toolhead board will have a version number too, what does your have?
soft birch
i can check. altho will take some time becase its hidden under some stuff
soft birch
i dont see a version number on the EBB SB2209 rp2040
but on the EBB SB0000 CAN it says version 1.0
dusky coyote
Well it should have one and that could make the differance in the correct settings.
Put the printer the correct way up and look on the front edge of the toolhead pcb
rapid bobcat
Ok
soft birch

There is no version number on it
soft birch
It says qc pass 08

a white sticker.
soft birch
Oh ok

OK so only thing I can think of, is that BTT started using a different setting in the katapult setting, MAYBE this is the issue but I don't think so as most people are good with the Eso's guide.
Once you have it back together, and powered on. What LEDs are on, on the toolboard.
dusky coyote
OK, double tap the reset button
soft birch
I tried that multiple times and it didn't work
dusky coyote
Does the command show anything now? ```python3 ~/katapult/scripts/flashtool.py -i can0 -q
OK then let try changing the katapult setting to what BTT say.
soft birch
Ok

And flash it as you did before.
soft birch

dusky coyote
