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

With an encoded crafting formula inserted, the player should see fake items with a red background appear in the grid while it's empty. Now, with auto-mode turned on, the assemblicator will try to use items in its stock area to craft the recipe endlessly.

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.

r/SkyFactory on Reddit: Why can't I use a Mekanism Formulaic Assemblicator to autocraft Mystical Agriculture Mystical Fertilizer?
September 13, 2021 -

I have the blank crafting formula and the valid recipe for the mystical fertilizer in the Formulaic Assemblicator, but it is not recognizing it as a valid recipe even though I put it straight in with JEI. The crafting formula has no recipe already encoded in it. If it's really obvious forgive me it's my first playthrough but I've used these assemblicators a bunch already.

r/Mekanism on Reddit: How do I get Formulaic Assemblicator to keep non-consumables...?
November 30, 2023 -

I'm currently playing All The Mods 8, and am trying to set up some automation for Mystical Agriculture Inferium Essence and whatnot, however I can't get the Master Infusion Crystal to stay in the input section (the crafting table slots), and as such, I have to constantly manually replace it, which makes it excruciatingly slow in comparison to just using a crafting table and manually putting every stack of Inferium in. No videos or forums I can find help explain any more than what I already know of how to use the Assemblicator or the Crafting Formulas. How do I get the non-consumed item to stay behind...?

r/allthemods on Reddit: Formulaic Assemblicator
January 16, 2023 -

I have a bunch of garden cloches set up to auto produce inferium essence for me that goes right into my refined storage system. I am trying to set up an auto crafting line with the mekanism formulaic assemblicators to condense the inferium essence into insanium essense and dump it back into my system. I made the line and set the recipes up but upon a single craft, the assemblicator auto ejects the master infusion crystal that i put in there into the next assemblicator which only allows one craft. Is there a way around this, because having to condense an overnight afk of inferium takes me so long because i get upwards fo 500k essence a day and each craft only takes 4 i would have to click over 100k times just to get the inferium to the next tier.

r/feedthebeast on Reddit: [FTB Infinity Lite]Mekanism - Formulaic Assemblicator
November 15, 2016 -

Hey folks!

We have some prolems with the automation / auto-mode of the formulaic assemblicator from mekanism. Is there any way to block slots in the inventory of the FA, so that there is always room for all the ingredients? We use Refined Storage as our Main Ressource Network and try to export from there.

As a workaround we use the automatic crafting from RS, but it would be nice to see a (simple) solution für the FA.
