Okay, folks, for anyone who doesn't know already, and to help prevent lag on the server (which is already creeping back in due to leaky machines apparently), here's how you make an overflow system.
First, you need an advanced distribution pipe. You make it the same way you would make a stone pipe, but with redstone on top of it. What it does is try to force any item that comes through it into the attached inventory, but if it won't fit, and ONLY if it won't fit, it sends it out to another pipe. You have to connect it with stone pipes, cobblestone won't work. What good does this do? Try this setup.
Say you have your precious cobblestone generator, or quarry, or whatever. It's happily working away at filling your chest with cobblestone. But what if your chest fills up? It's going to spew cobblestone everywhere. And that causes lag. The more crap that piles up, the more lag is generated. It's mostly noticeable only to people who have the chunk loaded from the client's standpoint, so if you're standing next to a leaky cobblestone generator that's what's really going to lag you, but it does stress the server if the chunk is loaded at all. Thus, you need a way to make sure that the cobblestone is taken care of properly. That's what advanced distribution pipes do.
Quarry goes to chest, but instead of having a stone pipe going into the chest, you have an adv. distribution pipe, with another stone pipe leading out. That stone pipe leads to your recyclers, all 10 of them or whatever. Advanced distribution pipes on top of the recyclers try to fit the cobble into those, starting with the first one, then moving to the second if it won't fit, then the third, or whatever. At the end, an open pipe above a pool of lava. Anything that is trying to be recycled that won't fit into the recyclers will now be destroyed instead of piling up into a lagarific mess.
Modify the system to suit your needs, but please, please use the advanced distribution pipes, and please, please have a lava bin to catch overflow and destroy it. Don't assume that having 3 or 4 or 5 recyclers will handle anything you throw at it...I've personally managed to overload a system of 10. And having a thousand recyclers won't do you any good if you accidentally let your power banks drain completely and they stop working, or if a creeper takes out a power cable, or something else happens that causes your recyclers to stop functioning properly. Any system that's capable of generating items without you personally putting them in there should have an overflow prevention method attached.
Thanks for this,
People need to bear in mind that poor planing into sloppy wiring can also cause mad lag. Cables that split too many times or even when there is a power back feed. The Lag very quickly adds up. Even with the improvements to the energy net system there's is still some issues. And like this guy said, We have additional pipes so use it. We don't need 200 long cobble pipes with no golden or anything. It does feel like cheating to use TP pipes but there easy point A to point B. The distribution pipes are hax to have as well. And if you don't like pipes, Redpower tubes have a built in functionality for overflow so if your new or don't care much for pipes please try those.
Admins also like to log in and play too. They run a server because they too like the game. When you see an Admin online tell them thanks for the hard work they do and let them enjoy the game so there motivated to keep playing and keep helping, We all have lives (but Maybe not me) so cut a them a bit of slack
working on the random crash issue from earlier today guys. Server will be up and down for a few. If you have any questions shoot me a PM.
