Nope. > **[CANBUS - Klipper documentation](https://www.klipper3d.org/CANBUS.html#usb-to-can-bus-bridge-mode)** As I said above, work at getting CAN working reliably first with more appropriate wiring your CanHat and then move onto the Octopus. We had something of a spirited conversation on the topic that you can read through here: > [@Setup EBB36 v1.2 connected to Octopus pro](https://klipper.discourse.group/t/setup-ebb36-v1-2-connected-to-octopus-pro/6617): > > 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 an octopus pro (and not use a can hat) The [GitHub - bigtreetech/EBB](http://github.com/bigtreetech/ebb) makes no sense to me. It appears to suggest install firmware\_USB.bin onto ebb board and add the code from sample-bigtreetech-ebb… You can setup Klipper on the Octopus to act as a CAN Bridge using a Klipper build like: ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/7/7408890059572b81ea2ae0a2011882fd2f17438b.png) CanBoot is installed before it and acts as a CAN bus bootloader with the purpose of providing a way of updating the firmware from the comfort of an SSH terminal but it isn’t necessary to run the CAN interface from the Octopus. However, I again highly recommend getting the wiring and a CanHat or U2C board interface working first. --- _[View the full topic](https://klipper.discourse.group/t/what-speed-is-minumum-for-can-bus-setup/6877)._
