Basic Information: Printer Model: V Core 3.1 500 MCU / Printerboard: btt Octopus Pro Lets continue the klipper noob adventures. For those already involved, thank you. The printer works and has printed a couple of calibration prints. Has anyone any experience of setting you the ebb36 v1.2 with…

I literally got CanBoot working on an Octopus V1.1 with the SB2040 (Voron) and Octopus V1.1 with EBB/42 (Custom CoreXY) last night/this morning. It’s not a horrendous experience, but it is horrendously poorly documented with the various pieces of documentation in conflict internally and with one an…

You are an absolute star. I will have a proper look and go through this process in the next few day. Thank you.

THIS IS ONLY INSTRUCTIONS FOR THE OCTOPUS BOARDS FOR CAN BUS BRIDGE. Make sure you have the canboot.bin and klipper.bin ready before starting these steps. See below for make menuconfig settings for CanBoot and Klipper for your STM32 version. We need the USB-C cable between the RPi and the Octopus. …

@NAPCAL , while I appreciate you posting this, can I say that as somebody who just spent 12+ hours getting CAN running on the Octopus and CAN toolhead boards that your script wouldn’t be any more helpful to somebody who is new to setting up CAN on their Octopus than the other references found here, o…

@mykepredko As for item 1. It is unclear if using make FLASH will wipe the flash memory as suggested by Arksine the creator of CanBoot. So using dfu-util directly with the bootloader starting address and switches 0x08000000:force:mass-erase Setting up CanBoot using the CAN bus port on the Octopus…

Thank you for the reply. Item 1. Could you explain “Setting up CanBoot using the CAN bus port on the Octopus will not allow you access to loading klipper since this setup uses the klipper CAN bus bridge; this is the reason for the next step.” I have had no problem using CanBoot to load two Octopus…

[image] mykepredko: Why don’t you like having the CAN bridge in the Octopus? It saves a bit of money and makes wiring things easier. I’ve printed enough since I got it running to feel like there isn’t a performance hit. I haven’t checked recently, but when I was using an Octopus in bridge mod…

It is a hassle to access the Voron’s electronics - especially to put in an SD card. Although I guess you could wire a switch across the Octopus’s Boot0 jumpers and program it using DFU. When there’s an update to Klipper, I’ll build new versions fo the Octopus and the Toolhead boards and let everyo…

@mykepredko Item 1; jakep_82 has pointed out one part. The other is CanBoot doesn’t have a CAN bridge mode, and with the settings to have it communicate via CAN bus, it will not be able to communicate with the RPi without Klipper firmware up and running CAN bridge mode. Item 2; with STM32F407, F42…

Have you read this CANBUS Communication timeout while homing Z?

Good luck.
