If you have AE autocrafting:
1. Teach AE how to make your saw of choice.
2. Teach AE each carving step along the way (cobble +saw = slabs, slab + saw = panels, etc.)
3. Set up an interface configured to keep a stack of cobble corners stocked at all times.
4. Your choice of item transport from interface to condenser.
5. ....
6. Profit
AE will autocraft new saws as the old ones break, craft whatever is needed to meet the demands of the interface, and will never "overcraft" the corners.
The advantage here over other autocrafting options is that AE will be smart enough to replace the saw as needed. Other methods will require additional work to manage the saws.
I think I will take this a slightly different route... I'm a bit of a distance from Autocrafting, but I have my Thaumic crystallizer all set up and Flying through materials... so I figure I would take advantage of that with an overflow buffer after it fills a drawer...
So, the "New Question" is: Which base item ( or magic crop) generates the highest aspect count per harvest? I'm back to thinking about the Tree Farm using FIR - if it will work. (fir logs have 4 aspect each and the byproduct of the saplings will keep my BioMass generators fed)
Magic crops: Wither skulls (2 plants, 8 essence, 20 aspects per skull)
Think I found the winner: Ghast tears!! (13 aspect per tear, 6 essence = 6 tear, one plant = 52 aspect)
Anyone find a better choice?
