Ok I guess that's expected, the relay isn't something that's specifically selected to work with Duet as I had it from other project. Anyways, it seems to be working fine so far when the inputs signals are fed through 1kohm resistor.
I did a couple of test prints, first with 2 extruders and after adding 2 more.
I'm toying with the idea of adding 2 more extruders, but need to desing a 6-port multiplexer part.

As I mentioned, the originl 4x joiner part had some trouble with some filaments, probably due to having too tight bends inside the part. To fix that, I desgined my own part, trying to have the paths bend as little as possible, while keeping the part relatively small. After few iterations I got a part that has been working without problems for few months now. I printed it with PETG, but ABS might be better as it has higher heat tolerances. Still, PETG seems to be holding up quite well.
