If I using the supplier pipe to replenish items that need to be synthesized, the supplier pipe will issue a synthesis request only when the quantity of all the raw materials required for the item to be synthesized is sufficient.

An example：
If I have a net：

• A supplier pipe，I set it supply 64 item A；
• A crafting pipe，using 4 item B to make 1 item A；
• A provider pipe，connect to a machine that can automatically generate item B，but the machine can store up to 64 item B.

The result is supplier pipe will supply nothing ，the supplier pipe will try using crafting pipe to make 64 item A then find don't have enough item B, so the supplier pipe will do nothing. But we konw the supplier pipe can supply 64 item A if it make 16 item A first and wait the machine generate another 64 item B then make next 16 item A...
And if I set the supplier pipe supply 16 item A, it will using 64 item B to make item A.
I try all mode of supplier pipe: Bulk50, Bulk100, Infinite, Partial, Full, the result is the same.
I know add the buffer size of machine (like a chest) can resolve the problem. But some recipes need many raw materials (like GT assembly line), so the buffer size should be very huge.

I think it is a good idea to add a new upgrade to supplier pipe. The upgrade make the supplier pipe can request carft part of item.

Oh, supplier only trigger crafting when there is enough item in system so it make sure nothing go wrong.
You can something to done it like tiny chest (ExtraUtil) and inf setting, i think?
