Here's how you can do autocrafting with redpower and either Gregtech or Tubestuff :
The advantage over Logistics Pipes is there is 0 chance of an item spill under any circumstances, and Eloraam is a better programmer so it is possible that it is less buggy. Also, mag tubes are faster than even diamond pipes.
How this works : for test purposes, the inputs are those 3 manager/diamond chests on the left. They have a priority of 0. The managers on the bottom pull items from the input to keep their respective autocrafting table stocked with raw materials. Those managers have a priority of 1. The managers on top supply any managers that wants the PRODUCT of autocrafting with that product. They have a priority of 0, and there is 1 instance of the item that
table makes in the slot so that they can "take back" unwanted instances of that item. Basically, the top managers have their gui in the "circular arrow" mode, the bottom managers are in the default exact stack mode.
Finally, the output. For a real build in survival, you'd want there to just be a few chests somewhere in the system where every single thing the factory makes is kept stocked in a few conveniently accessible chests. You stick a manager on each of those chests, and put however much of each item you want to keep in that chest in the manager's GUI.
So, for an example : as you can see, this factory needs the following items in order to be expanded :
1. Autocrafting Table. 2. Mag Accelerator 3. Mag Tube 4. Manager 5. Glass fiber (gregtech tables require power to run)
There's a complex multistep process to make each of these things, but once you have all that automated, you just have a single chest where a manager keeps it stocked with 1 stack of each.
One slight variant I found out that is not in this screenshot : stick a buffer between the top of the autocraft table from gregtech and the manager. Gregtech tables auto-output to that slot. This buffer helps it handle non-stacking
output items better, because if the manager "takes back" an output, it can go into the slots in the buffer.
