Used voron 2.4 save with software issues

[josephF]

Hello every one, I bought a used voron 2.4 locally, the printer is in very good mechanical shape but the seller did something silly by changing the toolhead to a can board unit and tried to reinstall klipper and now nothing works and the guy did not want to reinstall all the software properly.
So I am now with a completely built machine and no clue how to setup the all software/firmware side of it.
It runs on a pi 4 on witch I put klipper and mainseil with the KIAUH tool and now I managed to flash the mother board but i am quite lost when it come to configuring my printer.cfg file.
the only thing I know i that the seller did built a formbot kit and then added an BTT SB2240 can board.
I thing the next step is to configure the can board but i tried the esoteric guide but did not manage to fully set the board.This is on this particular point that I require help from you!

Thank you very much for your help,
Joseph

welcome to hell, (well until it is working) and if not careful, to the world of letting the smoke out of the 2240 board (trust me frustration and the want to do something quickly is not an excuse to try and disconnect/connect the card whilst it is still on).


first question, at the pi end of the equation, what have you got driving the canbus? There are a million options (or at least a dozen) however, for pure ease, any of the usb type canbus driver boards is going to make your life nice and easy. Also, if you are following the esoteric guide and didnt manage to set things up, then this could get ugly

Thank you very much for your answer, I did managed to get quite a bit further. I completely flashed both U2C 2.1 and SB2240 and did got them to run properly in klipper!
I also edited my printer.cfg file according to the BTT instruction found on Github but I still have some issues that I don't quite understand.
For example i don't know how to setup the TAP bed levelling through the canbus file (sample-bigtreetech-ebb-sb-canbus-v1.0.cfg) and the limit switches are also problematic because they are mounted on the toolhead and i don't know how and where I should set them up.
I hope you guys can give me some tips on what I should change on my config files. Here are my printer.cfg file and my sample-bigtreetech-ebb-sb-canbus-v1.0.cfg file :
