Hi, I have just built the Chromoss in my server I stacked it to the left one and up one as well (in total 4 modules) but the ones that got stacked horrizontally do not work. and i followed the tutorial and did it flipped as needed.
here it is (I added hoppers from the outputs so that is what all the hoppers are)
if you need a closer look at any parts to help me, please let me know and i can get those for you 🙂
here is a picture of the back as well
