Compact Iron Farm (needs gravel input)

[V1]: 5x5x8 iron farm with togglable iron packing, flint packing, flint destruction (just place lava under the flint funnels at the bottom of the farm).

Fairly easy to setup, just need to regulate gravel input with a nor gate with 3 other redstone links and a redstone torch:

• Input A: double gravel link set to receiver (for gravel temp storage)

• Input B: iron block+vault link set to receiver (for iron vault)

• Output C: gravel+iron link set to sender (for gravel to iron farm)

Then just place a gravel+iron link receiver on your gravel packager with iron farm sign destination.

If you want to keep the flint blocks, write your main storage frogport's input name and let it do the job.
