I had the same issue with every recipe in MA. I think it has something to do with the weird recipe locking with the prestige system. I honestly just moved to other packs like PO3 after finding that out. Answer from SgtStitchesVEVO on reddit.com

r/SkyFactory on Reddit: Formulaic Assemblicator
April 3, 2024 -

I made a formulaic assemblicator to craft stuff into ambers from bonsais, but I can’t figure out how to get items to input into the machine. I have figured out the formula and I get power to it just fine but I can’t get items into it, how to I input items into the assemblicator without doing it manually?

Place the Crafting Formula in the Crafting Formula Slot of the Formulaic Assemblicator. Place the items for the recipe you wish to craft in the Crafting Grid, and then click the Encode Formula Button. This will save the recipe for that item to the Crafting Formula.

To clear an encoded crafting formula, shift right click while holding it. While auto-mode is off, the player can use the assembler like a crafting table: the Craft Available Items button will craft as much as possible, using ingredients on the grid and in the stock area.

r/feedthebeast on Reddit: [SF4] Help with auto crafting/smelting resin and acorns with the assemblicator
May 15, 2019 -

Hey everyone,

I am playing SF4 with a friend and we can't figure out how to get the formulaic assemblicator to work for the life of us. The setup we are running is this.

We then have the itemducts bringing the items from the filing cabinet down to the assembilcator as shown here.

The problem lies with the filing cabinet and the itemducts. We have the assemblicator set to stock control: on but the pipes will only pull either acorns or resin down. They also do not pull in the correct quantity and we are getting stuck with a full inventory of either all resin or all acorns which won't allow the craft.

Any help would be greatly appreciated! We have tried processing cables which we couldn't get the filing cabinets to work with at all.

r/SkyFactory on Reddit: Mekanism Formulaic Assember
August 6, 2019 -

Hey,

Looking to get an auto crater set up for the fuel processing on my nuclearcraft reactor. Looking into the forumlaic assembler from Mekanism and I've got it up and running with auto input and output from / to my ME system just fine in manual mode.

The problem is I can't get it to do the crafting automatically, the "Auto Mode", "Encode Formula" and "Stock Control" buttons are all greyed out. Am I doing something wrong with my setup or is something disabled in this pack?

r/SkyFactory on Reddit: What Went Wrong Here? (Simple Storage/Mekanism)
May 30, 2019 -

So I'm kinda messing around in Creative with the concept of making pretty much the most compact Wither Farm I can come up with, and I think I'm missing some key information here to make this work. The other side of this farm works perfectly fine - stuff the materials into the Wither Builder, Mob Crusher kills it, loot sorting and all that with a bonus Exp tap.

The Build

Simply put, the left is a Material StoneWork Factory from Industrial Foregoing which is like a glorified Cobblestone Generator when given power. I'm using it to produce Sand. Nothing out of the ordinary here.

The Formulaic Assemblicator in the middle has an Encoded Crafting Formula in it set to "1 Sand + 1 Hellish Matter", which instructs it to craft the Soul Sand recipe. Auto mode and Stock Control on. Set auto-eject at the back to funnel into the Wither Builder behind it, and Input from the Processing Cable at the top. I can dump the materials in this thing and it'll craft Soul Sand and deposit it into the Builder just fine.

The Chest on the right has some Hellish Matter in it, as a placeholder for a Simulation Chamber with a Self-Aware Wither Skeleton Data Model. The pipe at the top would probably go somewhere where I can Autocraft or Wireless in an infinite stock of Polymer Clay. The Pristine Matter is funneled to the Loot Fabricator behind it and that's the Wither Skulls sorted.

Now I'm just left with the Processing Cable. The Exports both have Priority set to 1, with Sand and Hellish Matter whitelisted respectively. The Processing Cable itself has 1 Sand 1 Hellish Matter on the left, and 4 Soul Sand on the right.

Processing Cable

I even tried an alternative - the Retriever from Thermal Dynamics with a low stack/total size, but the Sand would eventually clog anyway and it'll be a pain to sync the materials together by fiddling with the Servos and Itemducts so they don't eventually clog.

I swear I've worked at this for 4 hours by the time I decided to ask for help, and I've been wracking my brains over what's going wrong with this set up and why it won't start funneling in the stuff to craft the Soul Sand. I don't know a thing about Simple Storage, and trust me I've tried to learn through countless Reddit Posts and videos to no avail. So... the tl;dr of this wall of text is that I don't get Simple Storage and I need help getting the two item inputs to go into the Assemblicator in equal intervals without clogging.

Edit: I'd also like some general advice on how to use these for Bonsai/Packager automation as well if possible, much appreciated!

Do you have the controller block required for the network to function connected? I don't see it in the picture. Edit: Also, for bonsais, I have all of mine going into a small AE network which only consists of import busses on the bonsais and storage busses on filing cabinets containing all of the drops I want (to start, this can actually just be done with simple storage import cables, but those become too slow once you start using mulch). I then have those cabinets connected to a separate simple storage network via storage cables and packagers connected with export cables, with each cable having the acorn and resin of a single resource with a stack size upgrade set to 32. I pipe I power from the top, have 3 of the sides used for each resource that that specific package makes, pipe out from the bottom, and have a sign on the last remaining side saying what resources are being made in it. I then use the fast itemducts to pipe items out to one of 4 cabinets, 2 which hold final products (ie dirt, redstone block, diamond, etc) and have a storage bus attached which connects to my main AE system, and 2 which hold Amber's, which are connected to another simple storage system to do the mekanism 3x processing, which I need to redo because I generate resources too quickly for a single ore processing setup, and will probably have 7 sets of ore tripling machines, one for each ore, and 3 sets of enrich->smelt for ardite, cobalt, and nickel since that is as far as they go. I should add that my bonsai farm has 8 of each sapling that I want (which is pretty much Menril and all of the sky orchard saplings minus the petrified, cookie, bacon, and donut) and they are all on the blue mulch, so they go incredibly fast.
