You stated the problem right there. 1 MV array = 8 LV arrays. If its going to make that from scratch its a pretty massive “tree” of crafting sequences that needs to be calculated. It triggers the abort because it thinks it’s stuck in a crafting loop, this is currently set at 800 crafts in one request if I remember correctly.

Currently no way of changing that, in the future the crafting resolution will work differently than today and will hopefully also better protect against overflow

Don’t really need an Enderchest for that kind of thing. Normal chests work too.

I like to keep a large supply of the very common items available so that the very complicated builds are more likely to succeed. I think the problem comes in when you need more than a full stack of the copper cable on multiple steps, creating a huge nested mess when the logistics pipes are trying to figure out what to do first.
I managed to get my HV solar panel production fully automated by having a chest that demanded 3 stacks of copper and 6 stacks of rubber all the time, then, separate from the rest of the logistics system, connected to a craft pipe connected to a autocrafting table for copper cable, and that connected to a chest with a supply pipe asking for the max amount of copper cable. Remember, this craft is off of the rest of the logistics system. Then connect the chest with the cable back to the main system via a provider pipe.
This doesn’t overflow, and it doesn’t loop its inventory, and it keeps a large amount of copper wire available for the huge builds that needs tons of it.
Only attempt to make 1 Hv Solar array, doing more than that really gets everything screwed up.
