I made my own mod pack and play on the latest version and I can’t find a guide on how to use both of these machines to eventually create crystallised obsidian

Tried this in my survival world, wasnt working so I cam to creative and I have this setup, but it's not making any crystallized amber, what am I doing wrong? Do I need a certain block underneath the solidification chamber?

Per the title. Struggling to get item insertion to work correctly for automation.

Issue I'm experiencing is that items being inserted into the Cyclic Solidification Chamber don't spread into all 3 slots. If items can stack, they will stack and not fill remaining slots.

Making concrete (yes I know there are other mods for this and yes I use these) requires 3 pieces of concrete powder. When inserting into the chamber, all 3 items go into the first, top slot. They don't spread and fill all 3.

The recipes themselves are mostly shapeless, so 3 different items can go in any of the 3 slots and the recipe will work. For where there are recipes that call for 3 of the same, or 2 of the same and 1 different, the same items stack and don't spread out.

I've tried several insertion methods. Hoppers, xNet, refined storage, ME, dispenser, pipez, modular routers, mekanism transporter, etc. If the item is capable of stacking, it will stack and not spread out.
