Two Duet 3 Mini 5+ and two toolboards over CAN

[Proschi3D]

How do I connect these 4 boards over CAN together?

Start by getting the two mini5s talking to each other.

I already have the two Duet 5 mini running. I just don’t quite understand how I need to wire the tollboards in between. The 2nd duet should be at the end, right?

I think I have understood it now?! I go from my first Duet 5 to the first toolboard, then CAN L and H are simultaneously also the output to the 2nd toolboard. From the 2nd toolboard the same then to the endboard Duet 5.

That's correct.
