I have around 16 ME controllers and a dense cable coming off of one with glass cable coming off of that. The problem is, it's not recognizing most of my interfaces and import buses that are clearly piped and connected to the network. I can provide screenshots.

How many machines are on that glass cable? If you exceed 8, only the nearest 8 (to the controller) will register. Dense itself can only handle 32 channels,if you exceed that it might be worth considering P2P. (or even if you exceed 8, depending on distance). Without a better description or screenshots I'm really just guessing though.

How do you make a P2P thingy? Lol. I have experimented before but I never understood it.

P2P, is essentially Moving things through an AE network, without them actually being on the network. The most common use for this is to avoid using the "expensive" Dense cable. In all honesty though, it depends entirely on distance which works out cheaper, if you only going about 10 blocks, the dense cable is likely going to be cheaper (It also depends on how much you value diamonds and fluix dust). The P2P Tunnels work in Pairs, and these must be on the same network, for obvious reasons. You'll also need a Memory Card to store the information on.

The main thing to rember, P2P is single input, multiple output. You Shift-right click on a P2P tunnel with the memory card to save its setting to the card. This makes it the Input Tunnel. You can then right click this Memory Card on other P2P tunnels on the same network in order to link them together. (I might have got this back to front, I sometimes mix these up.)

To the Tunneled System, it's pretty much treated as if both sides of the tunnel are right next to each other. This isn't just useful for reducing cost of cabling over long distances, it can also be used to transfer Liquids, Redstone Signals, Items, or Power over the network. It's a very flexible tool.

I have the dense cable come out of the controller and it says 8/32 channels. Do I put a P2P tunnel there, run glass cable from that to another one and put the settings on that and output to a dense cable... Or. This is sooo confusing.

With channels, you have to think about organizing in branching groups of 8. Each controller face can handle 4 groups of 8, as can each separate line of dense cable. Devices & all other cables can handle a single group of 8 per line. Only devices that store or transfer items use channels.

As described, 15 of your controllers are doing nothing but sucking down power & looking pretty. Most people, including me, tend to put in way more controllers than we will ever need.

Okay okay. I have no idea HOW I got it to work, but it works. Thanks guys!

Check that: it still doesn't work. My terminals and 2 interfaces aren't working ;-;

That is one overly complex setup....

I'd really suggest cleaning it up, channels always take the shortest route, and it can cause issues if there are multiple shortest routes. Additionally, the channels would be limited by the smallest cable en route. It'll also make it MUCH easier to debug.

You do know that a sole ME controller has the potential to host 192 devices right? (32channels a side X 6 sides of a cube.). You REALLY don't need that many.
You need to think of the controller as the heart of your system, dense cable as main arteries and the regular/smart cables as capillaries.
From one dense cable you can have 4 Regular/smart cables acting as capillaries branching off, each branch can host 8 devices on it's line (assuming there isn't devices that need 2 channels in one).
You could of course ham fist it and use all dense cable, but that's gonna get wasteful really quick and I don't think a lot of interfaces can be placed on dense cables.

Once you master the mechanics of channels you should then look in to P2P Tunnels ((point to point( yeah I thought it was Peer to Peer too))

Here's an example of how many devices can be supported by one mere controller face. Also cable anchors are your friends, as a regular/smart cable line can only handle 8 devices you don't want other lines crossing over, you can do this by coloring cables or using cable anchors which insulate cables from each other.

replace the glass cable that comes down from the dense to the controller with dense; continue replacing until it branches off and less than 8 channels are needed further down on both branches

Pretty much this.

Also @mattp_12 what is that little mass of dense cable not attached to the controller for? The cables right in the middle of the screen?

You have two controllers immediately adjacent to each other at the top of that pic. That's 64 channels you've wasted right there.

You cannot have two separate ME Controller Multiblocks (i.e. Controller - Cable - Controller). They have to be adajecent to one another.
