For your autocrafting setup, you need an ME Interface (can be the full-block version or the flat-panel version; both work) adjacent to one or more Molecular Assemblers. The Interface needs a channel; the Assemblers only need power. If you use the full-block Interface, it will share power and channels with/through the Assemblers; the panel version will not. The Interface needs to have your crafting patterns in the bottom slots; anything in the item configuration slots might break things. It does not need a crafting card- or any other upgrades, for that matter.
You'll also need at least one Crafting CPU- a multiblock structure- in order to actually be able to do any autocrafting. Just slap down a 1k crafting unit somewhere on your network; this'll be sufficient for crafting requests that don't have too many steps. Adding more crafting units (or upgrading the existing ones) will allow the CPU to process more complex crafting chains; adding Co-Processor units will allow the CPU to perform more than one step of the same crafting request at once. If any of your automation ends up having to perform multiple independent crafting requests at once (often happens with inscriber automation), you will need two totally separate crafting CPU multiblocks to make it work. Just make a few to be safe. Each multiblock needs its own channel. Also note that each individual CPU multiblock must be a cuboid composed entirely of the empty crafting units and any blocks crafted from them. There can be no holes, indentations, etc.
To request autocrafting on-demand, from an ME Terminal, you just need the above: an Interface with your crafting patterns on a Molecular Assembler and a crafting CPU. I'd recommend trying to request an ore gravel from a Terminal- that'll go a long ways toward diagnosing the problem.
If you want to produce items and stock them feed them into something automatically (such as your Pulverizer), you need an Export Bus or an Interface (but not one of those next to the Assemblers) with a Crafting Card. Configure the bus or interface to push/stock whatever item you want autocrafted (gravel ores, in your case), and if everything is set up correctly, it should work.
Also note that autocrafting does not, in general, work across subnets. If your crafting is one one subnetwork, and whatever's requesting the crafting (the terminal, interface, or export bus) is on another, it won't work. That could also be the issue. P2P and quantum bridges are fine; separate networks, no.
