The limitation solved from previous designs was the inserter speed, which was not feeding it fast enough. I used chests for bigger inputs to the assembly machines (which act as small buffers using combinators to keep their cargo size small). I added the maximum ammount of beacons and speed modules to the inserting speed of the machine. The result is as the title describes, to piss out 750 electronic circuits per minute.
The full speed module 3's on the copper wire production are not needed once the buffer settles so you can take half of them out, but I just used them for better accelaration.
When stacking, keep in mind that each 6 need:
4 x full blue belts of copper (might be 3,7 to 4,3)
2 x full blue belts of iron (might be 1,7 or 2,2)
3 x 75% full belts of electronic circuit output (make sure that you use a new belt for output every 2)
The output I got was 4.3k/m with 6 of them, the reason I am losing 0,05k/m I believe it to be that the output belt of every second one in the stack, is not allowing it to unload so fast as it would one a clean belt. Takes a few seconds to fill the buffers and reach the maximum speed.
If you test it in bigger stacks and can feed it, let me know how much output you could make and of course, if you think something can be better. Also, let me know if you fine tune and can calculate the ammount of full belts that it needs.
