@Exerqtor Do you find it more difficult to communicate with a different board than the Duet? Or does it remain simple with the CAN bus and just a matter of assigning some addresses?
I didn't know that Annex was stepping out of the open-source project. If I see that it doesn't work well, I'll get the ERCF. Even though I've already built the trad-rack. My real issue is that there aren't many configurations for RRF, and I'm not very skilled in 'free' programming. I like to experiment, but I don't have any studies that could help me. 🙂
