Flashed by us with canboot and klipper.

It was flashed with can bus speed 500000.

How to wire the board?

How do I connect the Board?

If you have a BTT Octopus there is a guide to connect this can toolhead directly to the RJ11 of the board using a bridge mode.

Although we recommend to leave it alone (it’s too much complicated) and use a middleman such as U2C that we also sell. The U2c is like an interpeter that will convert and read the CAN data. U2c connects via USB-C to the RPI and the can toolhead board can be connected to the U2C via 4 cables only.

This meand that you will reduce your cable harness from 17 cables to 4 cables only!
