EBB42 with some idle sensors/actuators
Hello! I am in need of your help regarding my newly built Vcore 3.1 400
I'm using an EBB42 1.2 (wired using this guide https://os.ratrig.com/docs/toolboards/btt/ebb-42-12/) and an Octopus 1.1.
The installation has been done with the RatOS configurator (selecting the boards properly).
You can find my printer.cfg in the thread.
What works:
- thermistor reading (ok, fluctuating at the same time as the bed's one)
- x endstop (I can home without problem and read the output in the console)
- inductive probe (same)
What does not work:
- heater (I read 0V with the multimeter when I put 60°C instructions)
- hotend fan (same, with M116 command)
What I didn't test:
- extruder (waiting for the hotend to work)
My analysis:
- EBB42 pinout is defined and linked to aliases in the EBB42 conf
- it's imported in cascade up to the printer.cfg
- we might have conflicts depending on the order of the imports, and the aliases are wrong
Questions:
- is there smg I missed in the conf?
- are there other tests I can do to better understand the issue?
- have you ever see such problem?
Thanks a lot for your reading time 🙂

upload your entire printer.cfg
Thanks! I didn't see the option when creating the post, much easier like this 🙂
Your config looks ok to me. How do you have it wired up?
the EBB42 is linked to the RPI4 via an USB cable, and in the heater case I just shoved the tester pins inside the heater plug 🙂
So you haven't run power lines to the EBB42?
In red I connected the 24V PSU to it (I'll check the voltage right away) and in blue I've set the jumper to use USB 5V for board power.
Voltage is good, 24V
The actual board
and you flashed the EBB42 with klipper?
maybe a silly question, you are sure it is the 1.2 version and not the 1.1 or 1.0?
Il not really sure how to check it out without dis-assembling to be honest, but it crossed my mind...
Do you have a tip to recognize it?
sorry I don't, I don't even use a toolboard to be honest
Np, I can flash as if 1.1 and try 😄
Will double check with my supplier! Thanks anyway 🙂
1.2
WHERE did that nice wiring pic for the EBB42 come from?
I might have SMG. The ebb42 is plugged in the RPI4, not the octopus board
dooohl! realized that after I posted.
just wish those pages had some refs to printer.cfg changes as well, for those converting. Some nice FROM: TO: references would be great Yes obviously there are a myriad of options based on hardware being used, but generics could be very valuable to mitigate repeated Q's here (like from this idiot... me that is)
If I plug the ebb42 to the octopus board, I loose the CAN connection... So not the way to go?
I reflashed the two boards without improvements
No problem 🙂 Don't hesitate to suggest changes then! I think you can make a PR?
A troubleshooting/QAs section could definitely help 😄
I feel like an idiot with this current issue lol, we can maybe make a club 😁

with the next configurator it will make the config for you and you will no longer need to deal with it
Interesting, it's written in the klipper logs that the can connection has been lost with the board when I plug it to the MCU. But it's definitely wired via USB.
Thanks for the article, I learnt a good load of stuff 😄
A friend of mine who has the same conf told me the EBB42 should be plugged in the RPI (seems logical, but I really wanted to rule that out)
Conf seems good too... Flashing was redone. Maybe reinstall RatOS but I don't really see the link... And the testing the hardware for faults.
I'm thinking wiring all pins to a same alias that I could trigger with a gcode command like m116

Are using a “USB-C v3.1 or greater” cable? Did you try a different cable or shorter one to just test for different results?
Ah! It's not clearly specified https://amzn.eu/d/0v7uEs6
So I'll fetch one which specifically says 3.1
For the length, it's the shortest that does the job.

Will keep you posted when I have the new one, thanks 😄
Nope, not changing a thing

Bummer. Hopefully will be rebuilding my hot end this weekend with one and will see if I have anything similar.

Have you tried removing the 5v jumper? I thought that the 24v powers the board as well, and the usb power is mainly for the first flash (same as the octopus boards work). But I’m not 100% sure.
Oh, and also check the end stop wiring. I saw someone say that they had theirs backwards and it stopped the board from booting.
It's funny, I've just had the conclusion that the board was damaged because it cannot work with the 5V jumper removed 😄
Thanks for your answer! I've checked that in cas but nope ^^
I just think the board is toast. I've wired the printer without and everything works... I'll make clean wiring diagrams for my printer, I'll share them here for doc sakes 🙂
