As a test, I'm crafting Stone Pickaxes.

Pattern:

Crafter Configuration:

Network has 2 creative bins attached, one for sticks, one for cobblestone. There's one Item Terminal to submit the request.

Occasionally, the crafter is getting items all in one stack. Like here:

I had requested 9 picks this time. It successfully crafted 8 of them and the 9th failed to insert the items properly. It always seems to happen on the last craft if it is going to happen, but doesn't happen every time. While testing this, I've had it happen about 50% of the time, however.

It's more reliable if I have more storage available on the network, though I certainly have enough to hold 9 picks here (2 barrels, plus the 6 slots in the Item Terminal).
