EBB42 v1.2 without max amplifier from BTT.

Flashed with canboot and klipper.

We flashed this board with can bus speed baud rate set at 1000000 (all orders before 9th of june were flashed at 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!

Do I need to flash anything?

No. We sell all of our boards pre flashed.

What do you need to upgrade to a CAN setup?
