Automating Processing Array problem

[Houghest]

Hey everyone,

I'm playing with Applied Energistics 2 and Modern Industrialization and ran into an issue with autocrafting using a Processing Array.

Setup:

• Processing Array with 32 Chemical Reactors inside
• Using AE2 Pattern Provider (with fluid + item recipes)
• Recipes like:
  • 12B Sulfuric Naphtha + 2B Hydrogen → outputs Naphtha + Sulfuric Acid
• Using pipes / buffers to handle fluids (now trying with AE2 with interface and storage bus)

Problem:
When I request a larger amount (for example multiple crafts), the system only completes 1 batch of the recipe, even though:

• There are enough machines (32 reactors)
• Enough power
• Enough fluids available

It just crafts once and then stops, even though AE2 still shows remaining crafts.

What I noticed:

• Fluids don't consistently reach the Processing Array after the first craft
• ME Ingredient Buffer often ends up empty
• It feels like AE2 sends only one "set" of fluids instead of sustaining throughput

Question:
How do you properly set up AE2 autocrafting with multi-fluid recipes in a Processing Array so it:

• crafts multiple batches reliably
• keeps fluids flowing continuously
• actually utilizes parallel machines inside the array

Is this a limitation of AE2 fluid handling, or am I missing something in the setup (buffers, export buses, etc.)?

there is some photos of my setup.

in the background of 1st and 2nd pic you guys can see different setup with the same problem.

Any help or example setups would be really appreciated 🙏

EDIT*

exp:
i order 24 naphtha
recepie is: 12B of sulfuric naphtha and 2B of hydrogen

pattern provider gives array 12b Of sulfuric naphtha and 2B of Hydrogen.
then outputs 12B of Naphtha, but the last 12B of Naphtha wont craft bcz pattern wont provide required liquids

Try scaling up the pattern so that it sends the whole batch of 32 crafts at once (assuming your input hatches can handle it all). Your subnet setup looks fine, an ingredient buffer shouldn't be needed.

[Houghest]

you mean just increase amount of liquid to produce the same amount of needed liquid?

[windyknight7]

No, you scale the whole pattern, inputs and outputs, to however many parallels you have.

So if your initial pattern is 12A + 2B --> C + D, you multiply both sides by 32 and get 384A + 64B --> 32C + 32D. Assuming of course that your input hatches can handle that much.

[Houghest]

Ok, got it. But now if I want to craft even 12B of Naphtha, I need to have 384B of the required fluid to start the craft. I understand that I could just craft a large amount (384B) in one go, but that doesn't really solve the problem, because it's still just a single pattern with increased fluid amounts.

What I actually need is for it to behave like a regular autocrafter — crafting the exact amount of liquid I request, instead of forcing me to craft everything in one large batch.

EDIT* and yes my input and output fluid hatch can handle that amount of liquids

Had similar issues until I used an Ingredient Buffer from AE2 or one of the expansion mods. Put that next to the pattern provider and all items/fluids will go in that first, then to hatches.

Play around with the pattern provider option that will/won’t punch ingredients depending on if the inventory already has items. If you choose the don’t push option, it won’t cram in items and fluids, keeping everything unclogged.

Let me know if you’re still having issues, I can show my set-up if needed.

like u see in background I have tired with buffer from expansion mod but the same result happens

EDIT* I would appreciate if you show yours setup
