Printer Model: Voron 2.4r2 300
OS: ubuntu-20.04-3.10-minimal-odroid-c1-20200519.img
CanBus: Bigtreetech U2C v1.0
MCU0: Odroid C1+
MCU1: BTT SKR 1.3 for Z axis
MCU2: BTT EBB 36 v1.2 SMT32G0B for extruder
MCU3: Havud 0.61 for gantry A/B motor not connected yet
The setup:
The idea is to use SKR 1.3 to control the Z axis and via canbus to control the XYcore and extruder.
Problem(s):
I managed to install klipper with some mishaps but it started working. But I’m facing a new problem that I can’t find a solution for. It’s about CANBUS, I managed to create the file for setting up and creating the network. I updated the BTT U2C as well as flashed the EBB36 firmware with a canbootloader. But when typing search command uuid it gives me an error. I entered a command to check IP network but canbus is missing.
When checking connected usb devices it is seen to be connected.
I tried different techniques to start the CANBUS like link here and this to.
If I am not mistaken, you didn’t enable the CAN interface at all and skipped the first step in the Klipper CAN manual:
It is also necessary to configure the host operating system to use the adapter. This is typically done by creating a new file named /etc/network/interfaces.d/can0 with the following contents:
auto can0
iface can0 can static
bitrate 500000
up ifconfig $IFACE txqueuelen 128
yes that’s what he should show me but he doesn’t want to. in VORON’s Discord channel they told me that ubuntu 20.04 is set up in a different way. it’s not like find out. there was something with NETPLAN, but I didn’t manage to do it
All the documentation I read said TransmitQueueLength needed to be in a .link file. Which didn’t work for me.
sudo nano /etc/systemd/network/80-can0.link
[Match]
Name=can0
[Link]
TransmitQueueLength=128
They must have changed it. It is still a fairly new feature from what I read. I’ll try it out next week when I get some parts in and I am messing with it again.
