I misunderstood, and using the wrong words in my question made things worse not better. My setups always had an OC "Adapter" directly connected to my ME Controller. As a consequence, at the very beginning of the script we are getting the component to proxy that communication. If your OC Adapter is connected to an ME Interface (rather than directly touching the controller) than at the beginning you need to have the component.proxy thing connect to an ME Interface rather than the controller. Having said that, I do not know if my script will work talking to the ME Interface, becau

I keep forgetting to post my significantly-improved versions of this. Sorry about that. My memory is that in 1.7.10 you actually cannot use the name-only item descriptor. In your test example try using the item ID for sand rather than "minecraft:sand". Does that make sense? So using NEI / JEI / whatever look up sand, and if it is item ID 27 then just use that. Might need to be (for example) minecraft:27 in that theoretical example. But what is going on with that crash is there is no error checking when the script attempts to check how many items you have of the requested ID. T

In JEI when you mouse over an item it should be the number after the slash ( / ) at the top of the item frame. I realize I have not been a good citizen and keeping up with this. I actually significantly improved this script in a 1.12.2 modpack and will post it when I have a chance. I also actually pared things down with better functions--thought I did not fold in the changes Dalden made for tracking current crafting. I shall try to pull that in as well and post the whole thing on Github.

It is possible this was implemented elsewhere and I failed to notice it, but I did this as an exercise as exploring OpenComputers. My son and I play The 1.7.10 Pack for our sandbox fun (in survival mode though), and I wanted to see if I could easily use OpenComputers to replace the typical-and-complex nest of level emitters and crafting cards to maintain minimum amounts of certain items in the AE2 ME network. This is not terribly sophisticated, and is just "fire-and-forget" with respects to requesting the crafting operations from the ME Network. As I continue to dabble I may add in chec
